is released. Version 1.5.0-alpha02 contains these commits.
New Features
- New APIs for querying camera features supported by the device. For example, checking if HDR and 60FPS can be enabled at the same time. It includes 2 artifacts: camera-feature-combination-query and camera-feature-combination-query-play-services.
This is a compatible version of camera2's
CameraManager#getCameraDeviceSetup#isSessionConfigurationSupported
API with additional data provided by Google Play Service.
Bug Fixes
- Fixed
Preview/VideoCapture
target frame rate issue on LEGACY level devices. The target frame rate set via thesetTargetFrameRate
orCamera2Interop
API was always overwritten to the value provided by theAeFpsRangeLegacyQuirk
. With this fix, CameraX library will respect the value set via thesetTargetFrameRate
orCamera2Interop
API. (Ie2d32) - Added flash/torch/3A functionalities for image captures with
CameraEffect
. The image captures withCameraEffect
should now have the same pre-capture and post-capture processings (e.g. flash trigger, 3A convergence etc. when applicable) as image capture without anyCameraEffect
. (I5ff30) - Excluded problematic output sizes for
ImageAnalysis
on Samsung SM-A057G device. WhenImageAnalysis
uses a resolution larger or equal to 1920x1440, it will cause black preview issue. AppliedExcludedSupportedSizesQuirk
to the SM-A057G device to avoid the issue. (I63dfe, b/365877975) - Fixed
Preview/VideoCapture
target frame rate issue when stream sharing mechanism is enabled internally to share a stream toPreview
andVideoCapture
. (I4fdac) - Enabled the workaround to fix the incorrect JPEG image metadata issue on Samsung S10e and S10+ devices. With the fix, CameraX can successfully save the JPEG image, or correct Bitmap objects can be returned when calling the
ImageProxy.toBitmap()
function on these devices if the incorrect JPEG image metadata issue happens. (Iae493, b/356428987) - Disabled extensions for Samsung A52s' back camera whose id is 0, because native crashes might happen when capturing HDR images and configuring capture sessions might fail for the BOKEH or FACE_RETOUCH modes. (I03ec9, b/364152642)
- Fixed the
VideoRecordEvent.Finalize.ERROR_INSUFFICIENT_STORAGE
event is not triggered when recording a video and there is insufficient storage space available. (Ia5b4f, b/356399842) - Fixed issue where second video recording attempt fails on Oppo A5 (CPH1931). (I181d6)

Bug Fixes
- Added flash/torch/3A functionalities for image captures with
CameraEffect
. The image captures withCameraEffect
should now have the same pre-capture and post-capture processings (e.g. flash trigger, 3A convergence etc. when applicable) as image capture without anyCameraEffect
. (I5ff30) - Optimized the pinch-to-zoom smoothness in
PreviewView
(I04ffc) - Decouple Ultra HDR from 10-bit output capability, as Ultra HDR support no longer requires devices to have 10-bit output capability. (I96ff2, I0c3b3)

is released. Version 1.4.0-alpha05 contains these commits.
New Features
- Converted
ProcessCameraProvider
into Kotlin implementation. (I46d4f) - Added
ImageCapture.takePicture
suspend functions to allow it to be called in a Kotlin-idiomatic way. (I920be)
API Changes
- Add output format APIs to
ImageCapture
, and addgetSupportedOutputFormats
method toImageCaptureCapabilities
for querying device capability. The default output format value isOUTPUT_FORMAT_JPEG
, which captures SDR images in JPEG format. When the device supports Ultra HDR and the output format is set toOUTPUT_FORMAT_JPEG_ULTRA_HDR
, CameraX will capture Ultra HDR compressed images using the JPEG/R image format. The format is backwards compatible with SDR JPEG format and supports HDR rendering of content. This means that on older apps or devices, images appear seamlessly as regular JPEG; on apps and devices that have been updated to fully support the format, images appear as HDR. (I5de50) - Add
PhysicalCameraInfo
inCameraInfo
to query physical camera information and add physical camera id setter/getter inCameraSelector
(Ic5b90) - Replace
CameraController#COORDINATE_SYSTEM_VIEW_REFERENCED
withImageAnalysis#COORDINATE_SYSTEM_VIEW_REFERENCED

RetryPolicy
API empowers developers to customize retry behavior for CameraX initialization. (I36dd2) - Enable creation of
ImageCaptureLatencyEstimate
object to assist with testability (Iaba99) - Add a
ImageAnalysis#COORDINATE_SYSTEM_SENSOR
. When this is used, theMlKitAnalyzer
returns coordinates in the camera sensor coordinate system. (I3ec61) - Exposed extensions metadata API. New
CameraExtensionsInfo
andCameraExtensionsControl
interfaces allow applications to monitor and adjust extension strength settings. Applications can obtain theCameraExtensionsInfo
orCameraExtensionsControl
instance via the newly addedExtensionsManager#getCameraExtensionsInfo()
orExtensionsManager#getCameraExtensionsControl()
methods. (I28e1a) - Added
ProcessCameraProvider.awaitInstance
which is a suspending version ofProcessCameraProvider.getInstance
(Ib22b9) - Add a
PreviewView#getSensorToViewTransform()
API. The Matrix represents the transformation from camera sensor coordinates to thePreviewView
's coordinates. This can be used to transform coordinates from oneUseCase
to another. For example, transforming the coordinates of detected objects inImageAnalysis
toPreviewView
overlay. (I947ab) - Make
camera-viewfinder-core
API more generic so it can be used bycamera-viewfinder
andcamera-viewfinder-compose
. (I1e295) - Add
getSurface
function toViewfinderSurfaceRequest
. (I781a0) - Use
camera-viewfinder-core
incamera-viewfinder
and deprecateViewfinderSurfaceRequest
andCameraViewfinder
. (I6198c) - Added
ZoomGestureDetector
that interprets scaling gestures specifically configured for pinch-to-zoom activity. (Ifafbf)
Bug Fixes
- Fixed
ImageAnalysis
' resolution selection issue related to the analyzer default target resolution setting: target resolution was incorrectly kept as 640x480 even if applications has set a different analyzer default resolution setting. If applications encounter this issue (1.3.0 ~ 1.3.2) and can't upgrade to use the newer version releases which contain the solution, directly setting aResolutionSelector
with the preferred resolution and a matchingAspectRatioStrategy
to theImageAnalysis
UseCase
can workaround this issue. (I81f72, b/330091012) - Fixed an issue that queued
takePicture
request might fail to run if the current request is failed. (Ie0801) - Make the invalid JPEG data check applied to Vivo X60 and X60 Pro devices. This can fix abnormally large image issue on these devices. (I82247, b/288828159)
- Fixed the incorrect JPEG image metadata issue on Samsung A24 devices. With the fix, CameraX can successfully save the JPEG image, or correct Bitmap objects can be returned when calling the
ImageProxy.toBitmap()
function on Samsung A24 devices. (I8d6eb, b/309005680) - Make the invalid JPEG data check applied to all Samsung devices if the captured image is larger than 10 MB. This can fix abnormally large iamge issue on Samsung devices. (Ic2a65, b/288828159)
- Removed
ImageAnalysis
support on CameraX Extensions as many OEMs' Extensions implementations don't work withImageAnalysis
well and might cause inconsistent issues. (I2d926)
Version 1.4.0-alpha04
January 24, 2024
androidx.camera:camera-*:1.4.0-alpha04
is released. Version 1.4.0-alpha04 contains these commits.
New Features
- New artifact: camera-effects: A library for applying real time effects to CameraX output, including
Preview
,VideoCapture
and/orImageCapture
. This artifact contains OpenGL implementations of theCameraEffect
API that manipulates the camera output efficiently. OverlayEffect
: for drawing overlays with Android’s Canvas API. This allows the app to apply a watermark or highlight detected objects on camera outputs.DynamicRange
APIs for the Preview Use Case: The dynamic range can now be set on the Preview Use Case, independently of the Video Use Case. This allows HDR dynamic ranges such as HLG10 for Preview alone. New APIs are also available inCameraInfo
to query which dynamic ranges each camera supports.
API Changes
- Renamed
ScreenFlashUiCompleter
toScreenFlashListener
and movedScreenFlashUiCompleter#getExpirationTimeMillis
toexpirationTimeMillis
parameter ofScreenFlash#apply
. (I13944) - New APIs added to allow dynamic range to be set on Preview use case, and to query dynamic ranges supported by each camera. This allows HDR dynamic ranges, such as HLG10, to be used with the Preview use case alone, no longer requiring a
VideoCapture
to be bound at the same time. (If25e3) - Renamed
getMirroring()
toisMirroring()
(I47063) - Added Realtime still capture latency estimate support in CameraX. Camera extensions enable applications to use an API that provides an estimate of how long a capture will take. The estimate takes into account the current environment conditions, the camera state and includes the time spent processing multi-frame capture requests along with any additional time for encoding processed buffers if necessary. (I05c3a)
- Renamed
ScreenFlashUiControl
toScreenFlash
,ScreenFlashUiControl#applyScreenFlashUi
toScreenFlash#apply
,ScreenFlashUiControl#clearScreenFlashUi
toScreenFlash#clear
, and addedgetScreenFlashUiApplyTimeoutSeconds
method instead of exposingSCREEN_FLASH_UI_APPLY_TIMEOUT_SECONDS
directly. (Iccdd0)
Bug Fixes
- Fixed a memory leakage that results in activities or fragments not being released when Extensions are enabled (I14215)
- Fixed the issue where
getZoomRatio
incorrectly returned a decreased value when applying an increasing zoom ratio. (I4aa0d, b/317543616) ImageCapture#ScreenFlash#clear
event is invoked immediately whenImageCapture
is unbound or camera is closed, also fixes some bugs where it is never invoked due to captures in these scenarios not completing properly. (If99f9)- Fixed the crash that happens when lifecycle is stopped before
takePicture
request is completed (Idf017, b/306202751) - Fixed the issue where camera preview becomes black when Extensions are enabled on some devices (I1ffd0)
- Fixed incorrect duration of video recording on devices using the Snapdragon 778G SoC. (If6aa7, b/316057919)
Version 1.4.0-alpha03
December 13, 2023
androidx.camera:camera-*:1.4.0-alpha03
is released. Version 1.4.0-alpha03 contains these commits.
New Features
- Added
CameraInfo.mustPlayShutterSound
to provide the information of whether a shutter sound must be played in accordance to regional restrictions. (Ifda84) - Added
OnImageCapturedCallback.onCaptureStarted
andOnImageSavedCallback.onCaptureStarted
for notifying when the camera has started exposing a frame. It's recommended to play the shutter sound or the shutter animation at this point. (Ic49b3) - Added Screen Flash feature support in CameraX for front camera image capture. CameraX will take care of the framework-side API handling and sync the timing with application's UI changes as required (e.g. AE precapture trigger after app screen color/brightness change). Apps will only need to add their UI side implementations in the
ScreenFlashUiControl
interface provided to CameraX. (I8ae84) - Added Screen Flash feature UI-side implementation support in CameraX. Apps will be able to get a basic
ImageCapture.ScreenFlashUiControl
implementation fromPreviewView
or the newly addedScreenFlashView
which will add a mono-color overlay view and maximize screen brightness during screen flash photo capture. (I1810e)
API Changes
- Supports new Extensions features(postview and capture process progress): Added
ImageCapture#getImageCaptureCapabilities()
APIs for apps to query the capabilities of the postview and capture process progress callback. Apps can enable the postview using theImageCapture.Builder#setPostviewEnabled()
. The postview size can be selected usingImageCapture.Builder#setPostviewResolutionSelector()
. When invokingtakePicture()
,onPostviewBitmapAvailable
andonCaptureProcessProgressed
can be implemented inOnImageSavedCallback
orOnImageCapturedCallback
to get the postview and process progress notification if supported. (I5cd88) - APIs for calculate coordinates transformation from sensor to the current buffer, with a flag indicating whether the Surface contains the camera orientation info. (I59096)
- Expose the API to query
PreviewCapabitlity
in PreviewUseCase
. (Ie5b6c) - Added APIs to support more qualities for
VideoCapture
.Recorder.Builder#setVideoCapabilitiesSource(int)
can be used withVIDEO_CAPABILITIES_SOURCE_CODEC_CAPABILITIES
to create aRecorder
instance which supports more qualities thanVIDEO_CAPABILITIES_SOURCE_CAMCORDER_PROFILE
. A common use case is when the application strives to record UHD video whenever feasible, but the device'sCamcorderProfile
does not include a UHD settings, even though the codec is capable of recording UHD video. (Iedbe2, b/263961771) - Add
ImageAnalysis
output format getter/setter toCameraController
. (I9a96c, b/308240643)
Bug Fixes
- From Camera
1.3.1
: Improved theProcessCameraProvider#bindToLifecycle()
performance. The major change is to optimize the process of identifying the most suitable size combinations forUseCases
. The optimal results vary based on the specificUseCase
combinations and the number of supported output sizes for the target devices. (I454f2) - Allow the use of
VideoCapture
when Extensions are enabled. (I91f32) - Fixed large captured JPEG image issue on Samsung A71 and M51 series devices. The captured JPEG images contain redundant 0's padding data in the JFIF compressed data segment. It causes the captured images to have extreme file size. Those redundant 0's padding data will be removed to make the captured images have normal image file sizes. (I01afc, b/288828159)
- Disable
ImageAnalysis
support on Pixels to avoid the bug on Pixel that returns the non-emptyImageAnalysis
supported sizes accidentally. (I7ec31) - Fixed performance issue where CPU loading and power consumption increased when Extensions are enabled. (Ibdccb)
- Added Snapdragon 480 to the
CameraUseInconsistentTimebaseQuirk
. This fixes an issue on Android 12 for devices using this chipset where the audio in recordings is offset by the amount of time the device is in a suspended state. (I58010)
Version 1.4.0-alpha02
October 18, 2023
androidx.camera:camera-*:1.4.0-alpha02

and rename the argument. (I72370) - Adding APIs to query the device capability and enable video/preview stabilization. (I87544)
- Provide API to customize the camera open retrying max timeout time. (I0c642)
- Released
ProcessCameraProvider.shutdownAsync
as a public testing API to allow process camera provider to be used in test suites which may need to initialize CameraX in different ways in between tests. (I9eca7) - Add APIs for configuring video capture dynamic range, frame rate and mirror mode. (Ifb8f7)
- Deprecate
OutputSize
and replace it withResolutionSelector
.ResolutionSelector
is a more comprehensive way to select resolutions, and it's consistent with the camera-core API. (I93abd, b/286801438)
Bug Fixes
- Fixed the black preview issue on Samsung Galaxy S23 Ultra 5G when Extensions Bokeh or Face-Retouch is enabled with
ImageAnalysis
on the rear camera. (I2e8b1) - Fixed Preview and

Bug Fixes
- Improve Extensions stability by ensuring that the initialization and deinitialization events are triggered in correct order. (Ib3b8e)
- Fixed capture session configuration failure for exceeding supported surface combination due to adding extra repeating surface internally. (Id718c)
- Fixed large captured JPEG image issue on Vivo S16 device. The captured JPEG images contain redundant 0's padding data in the JFIF compressed data segment. It causes the captured images to have large file size. Those redundant 0's padding data will be removed to make the captured images have normal image file sizes. (I79505, b/299069235)
- Fixed the issue that
ImageAnalysis
can't be bound together withImageCapture
and Preview when some extension modes are enabled on some devices. The fix will return correct value when apps query theImageAnalysis
availability viaExtensionsManager#isImageAnalysisSupported()
. (I7d538) - Update JavaDoc to match behavior. Instead of completes immediately, the
#setZoomRatio
,#setLinearZoom
and#enableTorch
wait until camera is ready. Also added information about how to get the maximum FOV with the#takePicture
API. (I23588)

Version 1.3.0-alpha06
April 19, 2023
androidx.camera:camera-*:1.3.0-alpha06
is released. Version 1.3.0-alpha06 contains these commits.
New Features
- Concurrent camera is a new feature introduced from Android 11, which supports simultaneous streaming of camera devices, for example, it allows a device to have both the front and back cameras operating at the same time. CameraX currently only supports dual concurrent cameras, which allows two cameras operating at the same time, with at most two {@link UseCase}s bound for each. The max resolution is 720p or 1440p, more details in the following link, see CameraManager#getConcurrentCameraIds()
- Introducing the new
ResolutionSelector
API which covers the following features:- Applications can specify aspect ratio and resolution strategies to select the best resolution for their needs.
- All sizes and aspect ratio parameters are expressed in the coordinates of the camera device sensor.
- Applications can implement a custom resolution filter to arrange the supported sizes in the desired order.
- Applications can also enable high resolution capture to obtain higher resolution images. However, please note that using a high resolution may result in slower capture times.
- Added
VideoCapture
mirroring APIs. Videos recorded byVideoCapture
are not mirrored by default. However, the camera preview is mirrored on the front camera by default.VideoCapture
mirroring APIs make it possible to align to the camera preview when using the front camera. There are threeMirrorMode
,OFF
,ON
andON_FRONT_ONLY
. To align to the camera preview, it is recommended to useON_FRONT_ONLY
which means that mirroring is not enabled for the rear camera but is enabled for the front camera.
API Changes
- Exposed new
ResolutionSelector
API. Applications can specify aspect ratio and resolution strategies with fallback rules or a custom resolution filter to get the desired results. Applications can specify a flag to enable high resolution capture. This will allow CameraX to select higher resolutions when taking photos or videos. However, please note that using a high resolution may result in slower capture times. (Ibed95) - The FPS ranges supported by the AE algorithm can now be queried via
CameraInfo#getSupportedFrameRateRanges()
. (Iaa67f) - Consolidate the names of all frame rate methods into using 'FrameRate'. Correct the javadoc mistake in
VideoCapture#getTargetFrameRate()
(I83304) - Deprecated the legacy
setTargetAspectRatio
andsetTargetResolution
API. Please use the newResolutionSelector
API instead. (I542c3) - Added public APIs for concurrent dual camera, including
List<List<CameraInfo>> getAvailableConcurrentCameraInfos()
ConcurrentCamera bindToLifecycle(@NonNull ConcurrentCameraConfig concurrentCameraConfig)
boolean isConcurrentCameraModeOn()
andConcurrentCameraConfig
,SingleCameraConfig
andConcurrentCamera
(Iab1c1)
- Make
ImageProcessor.Response#getOutputImage
NonNull (Ib9c60) - Added
VideoCapture
mirroring APIs, includingVideoCapture.Builder.setMirrorMode(int)
andVideoCapture.getMirrorMode()
. The APIs are useful for applications require the video recording to be consistent with common camera preview behavior, i.e. the rear camera preview is not mirrored but the front camera preview is mirrored. (I713b6, b/194634656) - Add
setTargetFrameRate()
API in theVideoCapture.Builder
andgetTargetFramerate()
API inVideoCapture
(I109d4) - Make
SurfaceOutput
extending Closable and hide SurfaceOutput.Event
's public constructor. (I60ea8) - Added
Recording.mute
to dynamically mute or unmute an in-processing recording.RecordingStats
will containAudioStats.AUDIO_STATE_MUTED
when the in-processing recording is muted explicitly. (Ie17fc) - Made
#setEffects()
parameter non-null. Add a#clearEffects()
API for clearing effects. The app should call#clearEffects()
to remove effects. (I4b4d9) - Add a second constructor for
ViewfinderSurfaceRequest.Builder
to take a builder for copy constructor (I621a7)
Bug Fixes
- Fixed the issue where apps invoking Extensions API could crash when closing the camera (Ib27e5)
- Fixed an issue where
VideoCapture
could not work with the front camera on some devices. For example, on Samsung Galaxy S23 and Xiaomi 2107113SG. (Ibec7e, b/270656244) - Fixed the issue where taking pictures using File in the external storage public folder will always fail in Android 10 or above. Please note that in Android 10, taking pictures using File in the external storage public folder also requires setting
requestLegacyExternalStorage
to true in application tag. (I11b2c) - Fixed a
RejectedExecutionException
crash inDefaultSurfaceProcessor
. The crash could happen whenVideoCapture
is bound and the activity is paused. (Idb46a, b/273713906)
Version 1.3.0-alpha05
March 22, 2023

bug that if the app handles screen orientation itself. the preview might become distorted upon rotation. This only happens on certain devices. It can be reproduced on Pixel a4, Pixel 5, and Pixel 6a. (I14340, b/223488673)
Version 1.3.0-alpha04
February 22, 2023
androidx.camera:camera-*:1.3.0-alpha04
is released. Version 1.3.0-alpha04 contains these commits.
New Features
A new feature to support previously unsupported Surface combinations by sharing one stream to multiple UseCases.
- Previously, when binding “Preview, VideoCapture, ImageAnalysis” on camera hardware level FULL and below, or binding “Preview, VideoCapture, ImageCapture” on hardware level LEGACY, CameraX throws
IllegalArgumentException
. - The new behavior is that the bindings will work without throwing exceptions. Instead, CameraX uses OpenGL to copy a shared stream to both Preview and VideoCapture.
- As the cost of the buffer copy, the app may see an increase in latency and power consumption.
API Changes
- Add API to convert
ImageProxy
toBitmap
. The supportedImageProxy
format isImageFormat.YUV_420_888
andPixelFormat.RGBA_8888

is released. Version 1.1.0-alpha12 contains these commits.
API Changes
- Removed unnecessary
@RequiresApi(21)
annotations from the inner classes/interfaces. (I8e286, b/204917951) - The quality constants and fallback strategy constants of
QualitySelector
have been changed to be represented by class objects. For example,QualitySelector.QUALITY_HD

Bug Fixes
- Fixed the issue that captured photos in
FLASH_AUTO
mode is underexposed in dark conditions on Pixel 3a and Pixel 3a XL (I13f19, b/205373142) - Always use latest display size to determine the preview
Resolution
. (I4a694) - Filtered out cameras which do not have
REQUEST_AVAILABLE_CAPABILITIES_BACKWARD_COMPATIBLE
. Cameras withREQUEST_AVAILABLE_CAPABILITIES_BACKWARD_COMPATIBLE
have the minimal set of capabilities that every camera device supports. Camera withoutREQUEST_AVAILABLE_CAPABILITIES_BACKWARD_COMPATIBLE
might be a camera to support special functionality and does not support standard color output.CameraX
can't support thePreview
,ImageCapture
,ImageAnalysis
orVideoCapture
use cases for those cameras. Therefore, those cameras should be filtered out to prevent incorrect usage. (Ib8cda) CameraSelector#filter
no longer throws anIllegalArgumentException
when the result set is empty. (I27804)- Smarter heuristics are now used to select encoder settings based on OEM specified profiles. (Iaeef0)

as the first alpha version for Video officially. There are several known issues to be fixed in the later releases.
API Changes
- Added
@RequiresApi(21)
annotation to all CameraX classes and dropped minSdkVersion from AndroidManifest.xml. This will allow camera-core to be easily integrated into applications that have a minSdkVersion less than 21, but want to conditionally use code paths that rely on API 21 and higher. For any application with minSdkVersion 21 or higher, this change requires no action. (Ie7f2e, b/200599470)
Bug Fixes
- Throw an InitializationException to make the app be able to gracefully handle the AssertionError happened when creating CameraCharacteristics. (Ibec79)

, and androidx.camera:camera-lifecycle:1.1.0-alpha09
are released. Version 1.1.0-alpha09 contains these commits.
API Changes
- ExperimentalUseCaseGroup annotation is removed now that the APIs are no longer experimental. (I01ef5)
Bug Fixes
- Fix the issue where the captured photos are blurred
in
MAXIMIZE_QUALITY
mode. (I173a9, b/193823892) - Fixed a Samsung Galaxy J5 issue that camera gets stuck after taking pictures with flash on/auto in dark environment (I3aab9)
- When cropping is needed for ImageCapture, compressing the output cropped image with the specified JPEG quality level according to the set capture mode. If the capture mode is
CAPTURE_MODE_MINIMIZE_LATENCY
, the JPEG compression quality will be 95. If the capture mode isCAPTURE_MODE_MAXIMIZE_QUALITY
, the JPEG compression quality will be 100. (Ieb37c, b/142856426)
Version 1.1.0-alpha08

androidx.camera:camera-camera2:1.1.0-alpha08
, androidx.camera:camera-core:1.1.0-alpha08
, and androidx.camera:camera-lifecycle:1.1.0-alpha08
are released. Version 1.1.0-alpha08 contains these commits.
New Features
- Add setOutputImageFormat API for image analysis config. User can select ImageAnalysis.OUTPUT_IMAGE_FORMAT_YUV_420_888 or ImageAnalysis.OUTPUT_IMAGE_FORMAT_RGBA_8888. By default, ImageAnalysis.OUTPUT_IMAGE_FORMAT_YUV_420_888 will be selected. (I7902d)
API Changes
- ExperimentalUseCaseGroupLifecycle annotation is removed now that the APIs are no longer experimental. (I17b85)
Bug Fixes
- Fixed Preview screen is too bright on the Huawei P20 Lite. This problem only occurs when certain special Preview resolutions are used together with a large zoom in value. (Idefce, b/192129158)
- Fixed an issue that flash is not working on some devices when setting flash mode to FLASH_MODE_ON shortly followed by taking pictures. (Ieb49b)
- Fixed the issue where Preview will halt for a while when taking pictures if VideoCapture, ImageCapture and Preview are bound. (I56197, b/193864120)
- Allows ImageAnalysis to select a resolution larger than 1080p. A LIMITED-level above device can support a RECORD size resolution for ImageAnalysis when it is bound together with Preview and ImageCapture. The trade-off is the selected resolution for the ImageCapture will also need to be a RECORD size resolution. To successfully select a RECORD size resolution for ImageAnalysis, a RECORD size target resolution should be set on both ImageCapture and ImageAnalysis. This indicates that the application clearly understands the trade-off and prefers the ImageAnalysis to have a larger resolution rather than the ImageCapture to have a MAXIMUM resolution. For the definitions of RECORD, MAXIMUM sizes and more details see https://developer.android.com/reference/android/hardware/camera2/CameraDevice#regular-capture. The RECORD size refers to the camera device's maximum supported recording resolution, as determined by CamcorderProfile. The MAXIMUM size refers to the camera device's maximum output resolution for that format or target from StreamConfigurationMap.getOutputSizes(int). (I1ee97, b/192911449)
- Add the Exif info to the captured image. (I01ff0, b/193342619)
- In ImageCapture, return the URI of the saved image if the saving location is File. (Ib5b49, b/149241379)

to directly retrieve information about the available cameras, which are either all of the device's cameras, or those selected by theCameraSelector
provided inCameraXConfig.Builder.setAvailableCamerasLimiter(CameraSelector)
. (Ieac08)
Bug Fixes
- CameraX now tries to force open a camera on the initial attempt, this may result in CameraX stealing the camera away from other camera clients when its app has a higher priority. (Iab069, b/175820568)
- Fixed the Robolectric test failure when setAvailableCamerasLimiter is used in CameraXConfig. (Ice307)
- This change catches the exception when the image queue is maxed out in ImageAnalysis. So instead of crashing, you may notice other use cases being frozen or sluggish. e.g. frozen/sluggish preview. (Ic12da, b/175851631)
- Fixed ExtensionsErrorListener to report errors when only Preview or ImageCapture is bound. (I5ae39)
- Fixed ImageCapture performance regression by removing the validation of image saved location before taking a picture. After making this change, if the save destination is invalid, it will take longer to get the failure response because it will try to save the image after the photo is taken. (I1fd4e, b/177061560)
- Fixed ImageCapture performance regression with "File" type OutputFileOptions. (I5164a, b/177061560)

Bug Fixes
- Fix format error in the document of
ProcessCameraProvider#getInstance
- Fixed the Robolectric test failure when setAvailableCamerasLimiter is used in CameraXConfig.
- Fixed ImageCapture performance regression by removing the validation of image saved location before taking a picture. After making this change, if the save destination is invalid, it will take longer to get the failure response because it will try to save the image after the photo is taken
- This change catches the exception when the image queue is maxed out in ImageAnalysis. So instead of crash, you may notice other use cases being frozen or sluggish. e.g. frozen/sluggish preview.
- Workaround included for intermittent corrupt image data in JPEGs on SM-G930T back-facing camera. (I52001, b/159831206)

parameter and pass in the current display. - Javadoc improvements for focus and metering APIs regarding
MeteringMode
and 3A Flags, and usage ofDisplay
parameter. - Expanded the reference documentation for
setZoomRatio
andsetLinearZoom
.
Bug fixes
- Fixed issues when closing then opening cameras resulting in "Precondition" check failure.
- Fixed a
ConcurrentModificationException
that could occur when using torch and zoom APIs. - Fixed issue to now select resolutions closer to requested resolution when a mod16 dimensions size is available.
startFocusMetering
andcancelFocusMetering
APIs now behave as documented, with correct timing and potentially returning errors when they occur.- Fixed issue when a specific target resolution was requested with a crop aspect ratio on a device that doesn’t support such sizes. Now, a non-cropped size of sufficient resolution to bound the original request will be selected when available.

Camera-Camera2 Version 1.0.0-alpha07
December 4, 2019
androidx.camera:camera-camera2:1.0.0-alpha07
is released. Version 1.0.0-alpha07 of camera-camera2 contains these commits
Camera2Config
is now available for use with initializing and configuring a Camera2-based implementation for CameraX. More details on how to use this in initialization are in the camera-core section of the release notes.- The camera2 interop functionally is now marked as experimental and moved to a separate package,
androidx.camera.camera2.interop.
Camera-Core Version 1.0.0-alpha07
December 4, 2019
androidx.camera:camera-core:1.0.0-alpha07
is released. Version 1.0.0-alpha07 of camera-core contains these commits
Note that there are some substantial changes in this Alpha release as we prepare for Beta. We recommend you review the changes and share any feedback you may have on the CameraX Google group. For those developers using CameraX in apps that are on the Play store, we recommend waiting for the formal Beta release before upgrading the library within your applications.
API changes
Important: CameraX initialization has changed. Applications should implement
CameraXConfig.Provider
, and use the defaultCamera2Config
provided byandroidx.camera.camera2
. A typical usage is:import androidx.camera.camera2.Camera2Config import androidx.camera.core.CameraXConfig public class MyCameraXApplication : Application(), CameraXConfig.Provider { override fun getCameraXConfig(): CameraXConfig { return Camera2Config.defaultConfig(this) } }
The CameraX class has been removed. The
bindToLifecycle()
,unbind()
,unbindAll()
,isBound()
, andhasCamera()
previously provided by the CameraX class call are now available via theProcessCameraProvider
.A per-process instance of
ProcessCameraProvider
is obtained asynchronously using the static methodProcessCameraProvider.getInstance()
, which returns a listenable future, which provides theProcessCameraProvider
on completion. Here it is shown inonCreate()
for a typical usage. You can place calls togetInstance()
later in the activity’s lifecycle to defer initialization latency to a later time (such as when a user action opens a camera UI).import androidx.camera.lifecycle.ProcessCameraProvider import com.google.common.util.concurrent.ListenableFuture class MainActivity : AppCompatActivity() { private lateinit var cameraProviderFuture : ListenableFuture<ProcessCameraProvider> override fun onCreate(savedInstanceState: Bundle?) { cameraProviderFuture = ProcessCameraProvider.getInstance(this); }
A listener can be added to the
ListenableFuture
returned bygetInstance()
. This ensures the camera provider can be retrieved from theFuture
without blocking onFuture.get()
cameraProviderFuture.addListener(Runnable { val cameraProvider = cameraProviderFuture.get() cameraProvider.bindToLifecycle(...) }, ContextCompat.getMainExecutor(this))
Camera selection is now done by a camera selector, instead of per-use case
val cameraSelector = CameraSelector.Builder().requireLensFacing(LensFacing.BACK).build()
CameraProvider.bindToLifecycle
is given the lifecycle owner, the camera selector, and use cases, which are then bound to the given lifecycle owner and run for the selected camera.cameraProvider.bindToLifecycle(this as LifecycleOwner, cameraSelector, preview, imageAnalysis)
Use case “Config” classes are removed. Instead, build use cases directly, setting options on each use case builder. For example:
preview = Preview.Builder().setTargetAspectRatio(AspectRatio.RATIO_16_9).build()
The Preview use case has been updated to accept a surface created and managed by the application to ensure Android best practices. It is highly recommended to use the
PreviewView
view class provided in the camera-view package.preview.setPreviewSurfaceProvider(previewView.previewSurfaceProvider)
See documentation for attaching an app-managed surface. In these cases the app manages the lifecycle of the surface.
Important: The
ImageAnalysis
Analyzer method implementation must callimage.close()
on received images when finished using them. Otherwise, new images may not be received or the camera may stall, depending on back pressure setting. Refer to the reference docs for details.ImageAnalysis ImageReaderMode
is now changed to a backpressure strategyintdef
.ImageProxy.getImage()
is marked as experimental. Applications should annotate usage for example via@androidx.camera.core.ExperimentalGetImage
The
UIThread
annotation requirement for theAnalyzer
has been removed.The
ImageAnalysis.clearAnalyzer()
function is added for removing an analyzer.Listeners with more than 1 method have been renamed to Callback:
ImageCapture.OnImageCapturedListener
is nowImageCapture.OnImageCapturedCallback
ImageCapture.OnImageSavedListener
is nowImageCapture.OnImageSavedCallback
VideoCapture.OnVideoSavedListener
is nowVideoCapture.OnVideoSavedCallback
Enums have changed to IntDef
Zoom controls have been added:
CameraControl.setLinearZoom()
CameraControl.setZoomRatio()
CameraInfo.getLinearZoom()
CameraInfo.getMaxZoomRatio()
CameraInfo.getZoomRatio()
CameraInfo.hasFlashUnit()
is added to determine if flash/torch hardware is present.CameraInfo.isFlashAvailable()
has been removed. Torch overrides flash functionality. More detail is included in the reference documentation.ImageCapture.Metadata
fields are replaced by get/set/is accessors.startFocusMetering
andcancelFocusMetering
now returnListenableFutures
which represent the asynchronous operation of the call.MeteringPoints
are now functioning as handles to metering actions, and are produced by factories. Apps should use the existing factories rather than custom factories.
Fixed issues
- Fixed issue when taking a picture on resuming (after a previous pause had take pictures pending completion).
- Known Issue:
CameraControl.enableTorch()
is functional but the returnedListenableFuture<Void>
is always an immediatecomplete(success)
future, even if there is no flash unit. Future versions will fix this to the final behavior: When there is no flash unit,enableTorch(true)
fails immediately (won't send request toCaptureSession
), andTorchState
remain Off. - Known Issue:
startFocusAndMetering
andcancelFocusAndMetering
start and cancel focus metering, but return an immediatelycompleted (success)
future not representing the documented behavior. TheFocusMeteringResult
fromListenableFuture<FocusMeteringResult> CameraControl.startFocusAndMetering()
is a fake result whichisFocusSuccessful()
and is always "false," differing from intended, documented behavior. - Known Issue: A metering point factory for use with
PreviewView
touch events is being developed. For now, apps connecting custom managed surfaces can use the existing metering point factories, and otherwise no touch focus functionality is available forPreviewView
.
Camera-Camera2 and Camera-Core Version 1.0.0-alpha06
October 9, 2019
androidx.camera:camera-camera2:1.0.0-alpha06
and androidx.camera:camera-core:1.0.0-alpha06
are released. These are the commits included in camera-camera2:1.0.0-alpha06
and these are the commits included in camera-core:1.0.0-alpha06
.
New features
Changes to setting aspect ratios:
setTargetAspectRatioMode()
was added and accepts an enum argument. This sets the Aspect Ratio Mode with optionsRATIO_4_3
orRATIO_16_9
instead of an arbitrary aspect ratio. This closer reflects the fact that only certain aspect ratios are provided from the camera, rather than any arbitrary ratio.- Currently, the only available ratios are 16:9 and 4:3. In the case of 1:1, only certain devices have this available from the camera, and then only at limited resolutions. Applications designing a 1:1 interface or processing should use the more flexible 16:9 or 4:3 choices and crop the display or process a subregion.
- These aspect ratios are oriented to use the maximum sensor area.
getTargetAspectRatio()
was added to use case config APIs, returning the aspect ratio the use case output is targeted for.- The method
setTargetAspectRatio(Rational aspectRatio)
has been changed for ImageCapture tosetTargetAspectRatioCustom(Rational aspectRatio)
. When set, the ImageCapture output crops accordingly.
Executor APIs
- The following functions accept an executor parameter, which allows the app to control which executor the function runs on.
Preview.setOnPreviewOutputUpdateListener()
API. If the executor is not present for that function, it executes on the main thread.Preview.setOnPreviewOutputUpdateListener
FocusMeteringAction.Builder.setAutoFocusCallback
ImageAnalysis.setAnalyzer
ImageCapture.takePicture
CameraView.takePicture
CameraView.startRecording
VideoCapture.startRecording
CameraInfo added with check Flash Available and Sensor Rotation APIs
Added
CameraInfo
and agetCameraInfo
method, which allows apps to check if a lens facing CameraInfo is available and if a flash is available on that camera. For example:try { CameraInfo cameraInfo = CameraX.getCameraInfo(currentCameraLensFacing); LiveData<Boolean> isFlashAvailable = cameraInfo.isFlashAvailable(); flashToggle.setVisibility(isFlashAvailable.getValue() ? View.VISIBLE : View.INVISIBLE); } catch (CameraInfoUnavailableException e) { Log.w(TAG, "Cannot get flash available information", e); flashToggle.setVisibility(View.VISIBLE); }
CameraInfo.getSensorRotationDegrees()
was added. It provides the camera sensor orientation relative to the device’s natural orientation, or for convenience, relative to an orientation described by a Surface rotation (which describes an orientation relative to natural orientation).
API changes and bug fixes
- Aspect Ratios: For each use case, applications should call only one of
setTargetResolution()
orsetTargetAspectRatio()
. Calling both on the same builder returns an error.- In general it’s recommended to use
setTargetAspectRatio()
based on the application’s UI design. Specific resolutions are based on the use case. For example, preview is near screen resolutions and image capture provides high resolution stills. See the automatic resolutions table for more information. - Use
setTargetResolution()
for more specific cases, such as when minimum (to save computation) or maximum resolutions (for processing details) are required.
- In general it’s recommended to use
- Executor API: Removed the
setCallbackHandler()
call from use case configuration APIs. Instead, applications can set the executor as a parameter in various other APIs that set a callback. - Updated null annotations for various functions.
- Fixed an issue that caused
java.lang.IllegalStateException at Camera$StateCallback.onError
to be thrown when opening the camera. - Fixed issue where resolutions would be selected that were too small (less than 640x480) when app is requesting larger or default resolutions resulting in a blocky or blurry preview image. Applications that specifically need smaller resolutions can explicitly request them.
- Fixed an issue where the camera would show black screen (failed to start the camera) after returning from an intent that launched another camera application.
- Fixed a bug that threw the following error when apps are repeatedly started or stopped;
java.lang.IllegalArgumentException: CaptureRequest contains unconfigured Input/Output Surface!
- Fixed the following error that occurs when disabling ImageAnalysis:
java.lang.IllegalStateException: maxImages (4) has already been acquired, call #close before acquiring more.
- Added additional tests for camera disconnect flow.
- Improved test system robustness when running back-to-back camera tests.

androidx.camera:camera-camera2:1.0.0-alpha05
and androidx.camera:camera-core:1.0.0-alpha05
are released. These are the commits included in camera-camera2:1.0.0-alpha05 and these are the commits included camera-core:1.0.0-alpha05.
API Change: Renamed use case error variables:
ImageCapture.UseCaseError
is renamedImageCapture.ImageCaptureError
VideoCapture.UseCaseError
is renamedVideoCapture.VideoCaptureError
Added
CameraControl
API w/Tap-to-Focus APIsAdded API to get a
CameraControl
from CameraX for a camera, selected by lens facing:CameraX.getCameraControl(LensFacing lensFacing)
Added
MeteringPointFactory
,MeteringPoint
,MeteringMode
, andFocusMeteringAction
to run Tap-to-Focus:MeteringPointFactory factory = new SensorOrientedMeteringPointFactory(width, height); MeteringPoint point = factory.createPoint(x, y); FocusMeteringAction action = FocusMeteringAction.Builder.from(point, MeteringMode.AF_ONLY) .addPoint(point2, MeteringMode.AE_ONLY) // could have many .setAutoFocusCallback(new OnAutoFocusListener(){ public void onFocusCompleted(boolean isSuccess) { } }) // auto calling cancelFocusAndMetering in 5 sec. .setAutoCancelDuration(5, TimeUnit.Second) .build();
Added API for
CameraControl
to start and cancel focus metering:getCameraControl(lensFacing).startFocusAndMetering(action);
getCameraControl(lensFacing).cancelFocusAndMetering();
Added APIs for Metering Point Factories that assist translating tap coordinates to sensor coordinates, based on view classes:
MeteringPointFactory factory = new TextureViewMeteringPointFactory(textureView);
MeteringPointFactory factory = new DisplayOrientedMeteringPointFactory(context, lensFacing, viewWidth, viewHeight);
Enforce calling the following methods on the Main (UI) thread, throwing an
IllegalStateException
when they are not. Future versions will allow usage on other threads and ensure serialization.CameraX.bindToLifecycle()
CameraX.unbind()
CameraX.unbindAll()
ImageAnalysis.setAnalyzer()
ImageAnalysis.getAnalyzer()
ImageAnalysis.removeAnalyzer()
Preview.removePreviewOutputListener()
Preview.getOnPreviewOutputUpdateListener()
Preview.setOnPreviewOutputUpdateListener()
Various config settings now accept null parameters and corresponding getters may return null.
Fixed issue when testing on emulators that do not support AF/AE/AWB settings.
Fixed crash bug on rotation while analyzing image.
Fixed bug where preview appears black on start (no camera data), after rotation or switching between front and back cameras.
Removed testing for multiple concurrent image analysis use cases. To ensure compatibility, applications should only attach a single image analysis use case.
Added initial robolectric tests for fake camera in camera-testing suite (WIP).
Camera2Inititalizer test removed, as its coverage was unclear/misleading.
Camera-Camera2 and Camera-Core Version 1.0.0-alpha04
August 7, 2019
androidx.camera:camera-camera2:1.0.0-alpha04
and androidx.camera:camera-core:1.0.0-alpha04
are released. Version 1.0.0-alpha04 contains these commits.
New Features
Changes to Aspect Ratio and Resolution selection
CameraX's goal is to successfully initialize a camera session. This means CameraX compromises on resolution/aspect ratios based on device capability, in order to start a capture session as its first goal, and so exact requests may not be honored. This may be due to:
- Devices not supporting the requested resolution
- Compatibility issues such as on LEGACY devices where certain resolutions must be used to operate correctly
- On some devices, certain formats are only available at certain aspect ratios
- A preference for a “nearest mod16” for JPEG or video encoding. See
CameraCharacteristics#SCALER_STREAM_CONFIGURATION_MAP
Although CameraX creates and manages the session, you should always check the returned image sizes on the use case output in your code and adjust accordingly.
Some changes have been made for setting resolutions and aspect ratios, intended to make the API more clear:
- Preview use case is now considered to have a default 4:3 aspect ratio when none is set.
- When CameraX internally considers changes to requested resolutions and aspect ratios based on device capability, it first tries to maintain the same aspect ratio (as determined by any of
setTargetAspectRatio
orsetTargetResolution
calls) - A “Nearest mod16” version of the resolution is considered as the same aspect ratio.
ImageAnalysis Non-Blocking Mode
- The behaviour of
ImageReaderMode.ACQUIRE_LATEST_IMAGE
is now non-blocking. It acquires the latest image in the queue, but discards unused images continuously to allow the camera pipeline to avoid blocking. - The analyzer can hold a single image indefinitely without stalling the pipeline.
- If the application provides an executor which then blocks, the ImageAnalysis use case blocks.
- The default executor set internally behaves as a non-blocking executor.
Bug Fixes
- Fixed timeout issues waiting for 3A convergence when capturing images on devices with no auto-focus, auto exposure, and auto-whitebalance
- Fixed issue when rapidly taking pictures with ImageCapture. Fixes error:
java.lang.IllegalStateException: maxImages (2) has already been acquired
- Fixed issue when
setLensFacing
was not called for a use case, resulting injava.lang.IllegalArgumentException: Unable to get camera ID for use case
. - Fixed issue where LEGACY device required specific aspect ratio as maximum JPEG resolution
- Fixed issue when backgrounding the app while camera is opening
- Fixed issue on API < 25, removing error
checkAndUpdateEglState: invalid current EGLDisplay
- Fixed issue when unbinding preview after enabling and starting extensions
- Build artifacts for camera-view and camera-extensions are now published as alpha versions

Camera-Extensions and Camera-View Version 1.0.0
Version 1.0.0-alpha32
December 15, 2021
androidx.camera:camera-extensions:1.0.0-alpha32
and androidx.camera:camera-view:1.0.0-alpha32
are released. Version 1.0.0-alpha32 contains these commits.
API Changes
- Removed unnecessary
@RequiresApi(21)
annotations from the inner classes/interfaces. (I8e286, b/204917951) - Update api files for camera-extensions artifact. (If683a, b/161377155)
Bug Fixes
- Disallow the app to enable extension modes when binding
VideoCapture
. CameraX Extensions only supportImageCapture
andPreview
. TheVideoCapture
can't be supported yet. If the app bindsVideoCapture
and enables any extension mode, anIllegalArgumentException
will be thrown. (I0d87b) CameraSelector#filter
no longer throws anIllegalArgumentException
when the result set is empty. (I27804)- Renamed
ExtensionsManager#getInstance
API asgetInstanceAsync
because it returnsListenableFuture
. The Async suffix of the function name can clearly present that it is an async function. (I279d2) - Remove resolution parameter from the
ExtensionsManager#getEstimatedCaptureLatencyRange
API since users can't know which sizes are supported for theImageCapture
use case and can't distinguish whether the returned latency information is for the maximum capture output size or the input resolution parameter. (I74bb2) - Move
CameraProvider
parameter ofExtensionsManager
functions to thegetInstance()
API. So that the users don't need to input theCameraProvider
parameter each time when calling theExtensionsManager
functions. (Ic7e48)
Version 1.0.0-alpha31
November 17, 2021
androidx.camera:camera-extensions:1.0.0-alpha31

are released. Version 1.0.0-alpha30 contains these commits.
API Changes
- Added @RequiresApi(21) annotation to all CameraX classes and dropped minSdkVersion from AndroidManifest.xml. This will allow camera-core to be easily integrated into applications that have a minSdkVersion less than 21, but want to conditionally use code paths that rely on API 21 and higher. For any application with minSdkVersion 21 or higher, this change requires no action. (Ie7f2e, b/200599470)
Bug Fixes
- Fixed the AbstractMethodError issue which happens when proguard is enabled. (Iae468, b/201177844)
Version 1.0.0-alpha29

are released. Version 1.0.0-alpha29 contains these commits.
API Changes
- ExperimentalUseCaseGroup annotation is removed now that the APIs are no longer experimental. (I01ef5)
- remove
RotationProvider#removeAllListeners()
. Please useRotationProvider#removeListener(...)
instead. (Id9d4a) - Updated the RotationReceiver class: changed set/clear Listener to add/remove/removeAll, remove the setListener variation that uses the main thread by default and added annotation of methods. (Ib1669)
Bug Fixes

is released. Version 1.0.0-alpha16 contains these commits.
API Changes
- Removed
PreviewView#setDeviceRotationForRemoteDisplayMode()
andPreviewView#getDeviceRotationForRemoteDisplayMode()
. The two methods are for customizing preview rotation, when desired rotation is not display rotation, e.g. remote display. To handle the non-display preview rotation now, set the desired rotation withPreview#setTargetRotation()
and the newly addedPreviewView#getViewPort(targetRotation)
. (Ib62cc) - Renamed
createSurfaceProvider()
togetSurfaceProvider()
. The method will always return the same instance of Preview.SurfaceProvider. (Iff83c)
Bug Fixes
- Forced PreviewView to use TextureView if extension effect is enabled and the vendor library implementation needs to do a special process on the output surface. (I0c3cc)
- Allow arbitrary target rotation for Preview. The transformation info is calculated and returned to user on-the-fly via a new
TranformationInfoListener
callback. (I21470)
Known Issues
- In PreviewView,
OnClickListener#onClick()
is not invoked when the end user clicks PreviewView. The touch event is mistakenly consumed by PreviewView#onTouchEvent(). The issue will be fixed in the next release. - The MeteringPoint obtained from
PreviewView#getMeteringPointFactory()
may be wrong if ViewPort is used with PreviewView.

Bug Fixes
DisplayOrientedMeteringPointFactory
takes in aCameraInfo
instance instead of aCameraSelector
so there is a direct mapping to which Camera the factory will be generating points for. All classes which useDisplayOrientedMeteringPointFactory
also take in aCameraInfo
instance instead ofCameraSelector
. (I400c1)- Removed
TextureViewMeteringPointFactory
.PreviewView
provides a public API (createMeteringPointFactory()
) to create a metering point factory regardless of whether it's using aTextureView
orSurfaceView
. (Ide693) - rename PreviewView's
SURFACE_VIEW
/TEXTURE_VIEW
implementation modes toPERFORMANCE
/COMPATIBLE
.PERFORMANCE
is the oldSURFACE_VIEW
mode, andCOMPATIBLE
is the oldTEXTURE_VIEW

API Changes
- Add
PreviewView#getPreviewStreamState
API which allows apps to observe if preview is streaming or not. When the PreviewView is in TEXTURE_VIEW mode, the STREAMING state also guarantees the preview image is visible. (Ic0906, b/154652477) - Added
PreviewView#setDeviceRotationForRemoteDisplayMode()
API to provide device rotation for transform calculations if the application is running in remote display mode. (I59b95, b/153514525)
Bug Fixes
- Fixed the preview distortion issue on
FULL/LIMITED/LEVEL_3
cameras running android 7.0 and below. Forced useImplementationMode#TEXTURE_VIEW
mode when the android version is 7.0 or below. (I83e30, b/155085307) - Removed the
CameraInfo
parameter fromPreviewView#createSurfaceProvider()
,PreviewView

. (If18f0, b/154652477) - Fixed the VideoCapture's default aspect ratio to be 16:9 in CameraView. (Ie6a7b, b/153237864)
- Fix
PreviewView
black screen issues when swiped outPreview
fragment and then swiped back in ViewPager2. Also fixed the issue whenremoveView(previewview)
and thenaddView(previewView)
. (Iab555, b/149877652, b/147354615) - Update the
CameraView#takePicture()
API to allow saving images toUri
andOutputStream
. Update the test app to useUri
as the canonical example. (Ia2459, b/153607583) - You can set PreviewView's scale type from a XML layout by setting the
ScaleType
attribute. (I08565, b/153015659) CameraView.ScaleType
has been removed. Instead, usePreviewView.ScaleType
to set/get a scale type with CameraView. (Ia8974, b/153014831)- Give
PreviewView
a background color by default if it doesn’t already have one. This prevents content behind it from being visible before the preview stream starts. (I09fad)

April 1, 2020
androidx.camera:camera-view:1.0.0-alpha09
is released. Version 1.0.0-alpha09 contains these commits.
Known Issues
- Using
ImplementationMode.SURFACE_VIEW
withPreviewView
may not work well on certain devices, this is because theSurfaceView
used for preview invalidates its surface when the lifecycle of the window it's in is stopped, when it restarts, the camera is reopened and may attempt to resume preview before theSurfaceView
's surface is valid again. For now, you should useImplementationMode.TEXTURE_VIEW
.
API Changes
- Renamed
PreviewView.setImplementationMode()
toPreviewView.setPreferredImplementationMode()
. - Renamed
PreviewView.getImplementationMode()
toPreviewView.getPreferredImplementationMode()
. - Replaced
PreviewView.getSurfaceProvider()
byPreviewView.createSurfaceProvider(CameraInfo)
, which takes a nullableCameraInfo
instance used to optimize preview by usingImplementationMode.SURFACE_VIEW
whenever possible. If a null instance is passed, or if you set the preferred implementation mode toImplementationMode.TEXTURE_VIEW
,ImplementationMode.TEXTURE_VIEW
is used internally. The following code sample shows how a preview use case used to previously be used with PreviewView.
preview.setSurfaceProvider(previewView.previewSurfaceProvider) cameraProvider.bindToLifecycle(lifecycleOwner, cameraSelector, preview)
Right now, you can write the following:
val camera = cameraProvider.bindToLifecycle(lifecycleOwner, cameraSelector, preview) previewView.preferredImplementationMode = ImplementationMode.TEXTURE_VIEW preview.setSurfaceProvider(previewView.createSurfaceProvider(camera.cameraInfo))
The
@UiThread
annotation has been added toPreviewView.getSurfaceProvider()
, meaning it must be called from the main thread. (I192f3)Added
PreviewView.setScaleType()
which allows to set the scale type of the preview. It accepts one of the values inPreviewView.ScaleType
, and defaults toPreviewView.ScaleType.FILL_CENTER
.Added
PreviewView.getScaleType()
.Removed support for setting the implementation mode for
PreviewView
in a XML layout using theimplementationMode
attribute.Add
createMeteringPointFactory()
API to PreviewView to support converting (x, y) inPreviewView
toMeteringPoint
. (Ib36d7)

- Fixed cases where an incorrect preview is displayed after
PreviewView
's size changes. (I71101)

Bug Fixes
- Replaced the
ListenableFuture
onSurfaceRequest.provideSurface()
with anExecutor
andCallback
. This simplifies the API by no longer requiring handling of exceptions onprovideSurface()
and enforces that theprovideSurface()
callback cannot be cancelled. This is to prevent crashes on older devices caused by prematurely releasing surfaces. TheSurfaceRequest.Result
object is now used for tracking how aSurfaceRequest
uses the providedSurface
. (I7854b) - Renamed
SurfaceRequest.setSurface(Surface)
toSurfaceRequest.provideSurface(Surface)
andSurfaceRequest.setWillNotComplete()
toSurfaceRequest.willNotProvideSurface()
. (I224fe) - Fixed initialization of app variants with ProGuard enabled by preserving the
flag that sets the default
CameraXConfig
provider. (I2d6c1)

February 10, 2020
androidx.camera:camera-view:1.0.0-alpha07
is released. Version 1.0.0-alpha07 contains these commits.
API Changes
PreviewView
'sTextureView
implementation now sets theTextureView
's size to the camera sensor output size before scaling it to fill its parentPreviewView
. If you want the camera preview to fill an entire part of the UI (the whole screen for instance), you should not set thePreviewView
's size to a fixed value, or have it wrap its content (by using the attribute "wrap_content
" for example), this may result in the camera preview only filling part of thePreviewView
(if the camera sensor output size is smaller). Instead, you should set thePreviewView
as big as its parent (by using the attribute "match_parent
" for example). (1204869)
Bug Fixes
- Updated
ImageCapture
to allow saving images toUri
andOutputStream
. Combined overloadedtakePicture
methods into one. Updated test app to useUri
as the canonical example. (Ia3bec) Preview.PreviewSurfaceProvider
has been renamed toPreview.SurfaceProvider
.SurfaceProvider
s no longer require developers to create their ownListenableFuture
, and providing aSurface
is now done through a newSurfaceRequest
object. ThePreview.getPreviewSurfaceProvider()
method has been removed due to its potential for misuse whenPreview
is paired with other classes such asPreviewView
. (I20105)- The arguments that were previously passed in
ImageCapture.OnImageSavedCallback.onError()
andImageCapture.OnImageCapturedCallback.onError()
have now been replaced by a single argumentImageCaptureException
, which still contains all the information that was previously passed. - The file argument previously passed in
ImageCapture.OnImageSavedCallback.onImageSaved()
has been removed. (I750d2) - API updated, with
getZoomRatio()
,getMaxZoomRatio()
,getMinZoomRatio()
, andgetLinearZoom()
methods ofCameraInfo
merging intogetZoomState()
which returns aZoomState
instance. (Ib19fe)

API changes
Checking for the availability and enabling of an extension now takes in a
