March 22, 2023

androidx.activity:activity:1.7.0 , androidx.activity:activity-compose:1.7.0 , and androidx.activity:activity-ktx:1.7.0 are released. Version 1.7.0 contains these commits.

Important changes since 1.6.0

The Photo Picker activity contracts in PickVisualMedia and PickMultipleVisualMedia have been updated to contain an additional fallback for when MediaStore.ACTION_PICK_IMAGES is unavailable that allows OEMs and system apps, such as Google Play services, to provide a consistent Photo Picker experience on a wider range of Android devices and API levels by implementing the fallback action . The Photo Picker will use this fallback if it is available before falling back to using Intent.ACTION_OPEN_DOCUMENT , which remains to support all API 19 and higher devices.
ComponentDialog now implements SavedStateRegistryOwner and has access to its own SavedStateRegistry and sets the SavedStateRegistryOwner for its ViewTree . It is now possible to use Jetpack Compose within a ComponentDialog as it meets both the LifecycleOwner and SavedStateRegistryOwner attached to the Window via the ViewTree APIs requirements.
IntentSenderRequest.Builder.setFlags() now allows you to set multiple flags from Intent , rather than only a single flag.

Kotlin Conversion

A number of Activity classes have been converted to Kotlin. All converted classes still retain their binary compatibility with previous versions. The following classes have source incompatible changes for classes written in Kotlin: ActivityResultRegistryOwner , OnBackPressedDispatcherOwner .

The table below provides the source conversions for the new version of Activity:

Activity 1.5	Activity 1.6
`override fun getActivityResultRegistry() = activityResultRegistry`	`override val activityResultRegistry = activityResultRegistry`
`override fun getOnBackPressedDispatcher() = onBackPressedDispatcher`	`override val onBackPressedDispatcher = onBackPressedDispatcher`

These classes were also converted to Kotlin, but remain source compatible: ContextAware , ContextAwareHelper , OnContextAvailableListener , IntentSenderRequest , and OnBackPressedDispatcher

FullyDrawnReporter APIs

ComponentActivity now provides a FullyDrawnReporter instance that allows multiple components to report when they are ready for interaction. ComponentActivity will wait for all components to complete before calling reportFullyDrawn() on your behalf. These APIs take care of the timing requirements for you and do not need to be called as part of an onDraw call.

These APIs are encouraged to enable:

Signaling the Android Runtime when startup completes, to ensure all of the code run during a multi-frame startup sequence is included and prioritized for background compilation.
Signaling Macrobenchmark and Play Vitals when your application should be considered fully drawn for startup metrics, so you can track performance.

Three Activity Compose APIs have been added to make it more convenient to use the FullyDrawnReporter from individual composables:

ReportDrawn indicates that your composable is immediately ready for interaction.
ReportDrawnWhen takes a predicate (ie, list.count > 0 ) to indicate when your composable is ready for interaction.
ReportDrawnAfter takes a suspending method that, when it completes, indicates that you are ready for interaction.

API Changes

The action and extra used by the PickVisualMedia and PickMultipleVisualMedia contracts as a fallback for when MediaStore.ACTION_PICK_IMAGES is unavailable are now public constants that provide API stability to OEMs and system apps that want to provide a consistent Photo Picker experience.

নতুন বৈশিষ্ট্য

AndroidX ComponentActivity now implements the MenuHost interface.. This allows any component to add menu items to the ActionBar by adding a MenuProvider instance to the activity. Each MenuProvider can optionally be added with a Lifecycle that will automatically control the visibility of those menu items based on the Lifecycle state and handle the removal of the MenuProvider when the Lifecycle is destroyed. ( I3b608 ):

/**
  * Using the addMenuProvider() API directly in your Activity
  **/
class ExampleActivity : ComponentActivity(R.layout.activity_example) {

  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)

    // Add menu items without overriding methods in the Activity
   addMenuProvider(object : MenuProvider {
      override fun onCreateMenu(menu: Menu, menuInflater: MenuInflater) {
        // Add menu items here
        menuInflater.inflate(R.menu.example_menu, menu)
      }

      override fun onMenuItemSelected(menuItem: MenuItem): Boolean {
        // Handle the menu selection
        return true
      }
    })
  }
}

/**
  * Using the addMenuProvider() API in a Fragment
  **/
class ExampleFragment : Fragment(R.layout.fragment_example) {

  override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    // The usage of an interface lets you inject your own implementation
    val menuHost: MenuHost = requireActivity()
  
    // Add menu items without using the Fragment Menu APIs
    // Note how we can tie the MenuProvider to the viewLifecycleOwner
    // and an optional Lifecycle.State (here, RESUMED) to indicate when
    // the menu should be visible
    menuHost.addMenuProvider(object : MenuProvider {
      override fun onCreateMenu(menu: Menu, menuInflater: MenuInflater) {
        // Add menu items here
        menuInflater.inflate(R.menu.example_menu, menu)
      }

      override fun onMenuItemSelected(menuItem: MenuItem): Boolean {
        // Handle the menu selection
        return true
      }
    }, viewLifecycleOwner, Lifecycle.State.RESUMED)
  }

Behavior Changes

The ActivityResultRegistry will now throw an IllegalStateException when attempting to call launch() on an ActivityResultLauncher that has not be registered or that has been unregistered. ( Ida75d , b/192567522 )

Major changes since 1.1.0

Activity Result APIs : ComponentActivity now provides an ActivityResultRegistry that lets you handle startActivityForResult() + onActivityResult() as well as requestPermissions() + onRequestPermissionsResult() flows without overriding methods in your Activity or Fragment, brings increased type safety via ActivityResultContract , and provides hooks for testing these flows. See the updated Getting a Result from an Activity .

ContextAware : ComponentActivity now implements ContextAware , allowing you to add one or more OnContextAvailableListener instances which will receive a callback before the base Activity.onCreate() .
- A suspending Kotlin extension withContextAvailable() allows you to run a non-suspending block when the Context becomes available and return a result.
- This API is used by FragmentActivity in Fragment 1.3.0 to restore the state of the FragmentManager . Any listeners added to subclasses of FragmentActivity will run after that listener.
- This API is used by AppCompatActivity in AppCompat 1.3.0-alpha02 or higher. Any listeners added to subclasses of AppCompatActivity will run after that listener.
ViewTree Support : ComponentActivity now supports the ViewTreeLifecycleOwner.get(View) , ViewTreeViewModelStoreOwner.get(View) , and ViewTreeSavedStateRegistryOwner APIs added in Lifecycle 2.3.0 and SavedState 1.1.0 such that it will return the Activity as the LifecycleOwner , ViewModelStoreOwner , and SavedStateRegistryOwner for any Views directly added to the ComponentActivity .

reportFullyDrawn() backport - The Activity method of reportFullyDrawn() has been backported in ComponentActivity to work on all API levels, fixing a crash on API 19 and adding tracing for this method for all API levels.

The previously available Dial contract has been removed as that Intent is not meant to be used with startActivityForResult() . ( aosp/1266916 )
Many of the Activity Result APIs not meant to be extended are now final . This includes getActivityResultRegistry() , the prepareCall() methods, all methods of ActivityResultRegistry except invoke() , and a number of the default contracts that do not support optional extras. ( b/152439361 )

৫ সেপ্টেম্বর, ২০১৯

androidx.activity:activity:1.0.0 and androidx.activity:activity-ktx:1.0.0 are released. The commits included in this version can be found here .

Major Features of 1.0.0

ComponentActivity : ComponentActivity serves as the new base class for FragmentActivity in Fragment 1.1.0 and, by extension, AppCompatActivity in AppCompat 1.1.0 .
activity-ktx : The activity-ktx module includes a by viewModels Kotlin property extension for accessing ViewModels. This module is automatically included when you include fragment-ktx from Fragment 1.1.0 .
OnBackPressedDispatcher : As a composable alternative to overriding onBackPressed() , you can now register a OnBackPressedCallback from any LifecycleOwner (such as a fragment) to intercept system back button events. A lambda with receiver version addCallback has been added to activity-ktx . See Provide custom back navigation documentation for more details.
onRetainCustomNonConfigurationInstance deprecation : the onRetainCustomNonConfigurationInstance() and the related getLastCustomNonConfigurationInstance() APIs have been deprecated. It is strongly recommended to use ViewModels to store non-configuration state as they offer a composable solution suitable for any ViewModelStoreOwner that makes the ownership of the retained objects clear and provides an onCleared() callback for cleaning up resources when the activity is finally destroyed.

This release makes significant changes to the handling of the onBackPressed() . See the updated custom back documentation for more details.

The methods for OnBackPressedCallback and OnBackPressedDispatcher have been marked as @MainThread . ( aosp/943813 )
The handleOnBackPressed() method no longer returns a boolean . Instead, OnBackPressedCallback is now an abstract class that can be enabled or disabled - only when the new isEnabled() method returns true will handleOnBackPressed() be called, in which you must handle the back button. ( aosp/944518 )
The addCallback methods of OnBackPressedDispatcher no longer return a Cancellable instance. OnBackPressedCallback now contain a remove() method that fulfill this functionality, allowing you to call remove() during handleOnBackPressed() . ( aosp/944519 ) ( aosp/946316 )

Methods to add a new OnBackPressedCallback to the OnBackPressedDispatcher now return a Cancellable object, allowing removal of the callback without requiring an explicit reference to the OnBackPressedDispatcher . ( aosp/922523 )
Adding a OnBackPressedCallback with an associated LifecycleOwner now results in adding and removing the OnBackPressedCallback as the Lifecycle is started and stopped, respectively. ( aosp/922523 )

Important changes since 1.7.0

Predictive Back - The OnBackPressedCallback now offers new Predictive Back callbacks for handling the back gesture starting, progress throughout the gesture, and the back gesture being canceled in addition to the previous handleOnBackPressed() callback for when the back gesture is committed. This also comes with the PredictiveBackHandler Composable to handle predictive back gesture events in Activity Compose. It provides a Flow of BackEventCompat objects that must be collected in the suspending lamba you provide:

  PredictiveBackHandler { progress: Flow<BackEventCompat> ->
    // code for gesture back started
    try {
      progress.collect { backEvent ->
      // code for progress
    }
    // code for completion
    } catch (e: CancellationException) {
      // code for cancellation
    }
  }

ComponentActivity.onBackPressed() has now been deprecated in favor of the APIs for handling back. Developers should now utilize the OnBackPressedDispatcher , rather than overriding this method.

EdgeToEdge - ComponentActivity.enableEdgeToEdge() has been added to easily set up the edge-to-edge display in a backward-compatible manner.

API Changes

Activity now provides a BackEventCompat class that serves as a backward compatible version of BackEvent that is decoupled from the framework BackEvent class.
Breaking change: The handleOnBackStarted and handleOnBackProgressed methods of OnBackPressedCallback now receive an androidx.activity.BackEventCompat instance rather than a framework android.window.BackEvent class. The equivalent @VisibleForTesting APIs on OnBackPressedDispatcher have also been updated.
The constructor for OnBackPressedDispatcher now takes an optional Consumer<Boolean> instance that allows the owners of the dispatcher to receive a callback whenever the number of enabled callbacks changes from zero to non-zero or vice versa.

Important changes since 1.6.0

The Photo Picker activity contracts in PickVisualMedia and PickMultipleVisualMedia have been updated to contain an additional fallback for when MediaStore.ACTION_PICK_IMAGES is unavailable that allows OEMs and system apps, such as Google Play services, to provide a consistent Photo Picker experience on a wider range of Android devices and API levels by implementing the fallback action . The Photo Picker will use this fallback if it is available before falling back to using Intent.ACTION_OPEN_DOCUMENT , which remains to support all API 19 and higher devices.
ComponentDialog now implements SavedStateRegistryOwner and has access to its own SavedStateRegistry and sets the SavedStateRegistryOwner for its ViewTree . It is now possible to use Jetpack Compose within a ComponentDialog as it meets both the LifecycleOwner and SavedStateRegistryOwner attached to the Window via the ViewTree APIs requirements.
IntentSenderRequest.Builder.setFlags() now allows you to set multiple flags from Intent , rather than only a single flag.

Kotlin Conversion

The table below provides the source conversions for the new version of Activity:

Activity 1.5	Activity 1.6
`override fun getActivityResultRegistry() = activityResultRegistry`	`override val activityResultRegistry = activityResultRegistry`
`override fun getOnBackPressedDispatcher() = onBackPressedDispatcher`	`override val onBackPressedDispatcher = onBackPressedDispatcher`

These classes were also converted to Kotlin, but remain source compatible: ContextAware , ContextAwareHelper , OnContextAvailableListener , IntentSenderRequest , and OnBackPressedDispatcher

FullyDrawnReporter APIs

These APIs are encouraged to enable:

Signaling the Android Runtime when startup completes, to ensure all of the code run during a multi-frame startup sequence is included and prioritized for background compilation.
Signaling Macrobenchmark and Play Vitals when your application should be considered fully drawn for startup metrics, so you can track performance.

Three Activity Compose APIs have been added to make it more convenient to use the FullyDrawnReporter from individual composables:

ReportDrawn indicates that your composable is immediately ready for interaction.
ReportDrawnWhen takes a predicate (ie, list.count > 0 ) to indicate when your composable is ready for interaction.
ReportDrawnAfter takes a suspending method that, when it completes, indicates that you are ready for interaction.

FullyDrawnReporter APIs

These APIs are encouraged to enable:

Signaling the Android Runtime when startup completes, to ensure all of the code run during a multi-frame startup sequence is included and prioritized for background compilation.
Signaling Macrobenchmark and Play Vitals when your application should be considered fully drawn for startup metrics, so you can track performance.

Two Activity Compose APIs have been added to make it more convenient to use the FullyDrawnReporter from individual composables:

ReportDrawnWhen takes a predicate (ie, list.count > 0 ) to indicate when your composable is ready for interaction.
ReportDrawnAfter takes a suspending method that, when it completes, indicates that you are ready for interaction.

Major changes since 1.1.0

Activity Result APIs : ComponentActivity now provides an ActivityResultRegistry that lets you handle startActivityForResult() + onActivityResult() as well as requestPermissions() + onRequestPermissionsResult() flows without overriding methods in your Activity or Fragment, brings increased type safety via ActivityResultContract , and provides hooks for testing these flows. See the updated Getting a Result from an Activity .

ContextAware : ComponentActivity now implements ContextAware , allowing you to add one or more OnContextAvailableListener instances which will receive a callback before the base Activity.onCreate() .
- A suspending Kotlin extension withContextAvailable() allows you to run a non-suspending block when the Context becomes available and return a result.
- This API is used by FragmentActivity in Fragment 1.3.0 to restore the state of the FragmentManager . Any listeners added to subclasses of FragmentActivity will run after that listener.
- This API is used by AppCompatActivity in AppCompat 1.3.0-alpha02 or higher. Any listeners added to subclasses of AppCompatActivity will run after that listener.
ViewTree Support : ComponentActivity now supports the ViewTreeLifecycleOwner.get(View) , ViewTreeViewModelStoreOwner.get(View) , and ViewTreeSavedStateRegistryOwner APIs added in Lifecycle 2.3.0 and SavedState 1.1.0 such that it will return the Activity as the LifecycleOwner , ViewModelStoreOwner , and SavedStateRegistryOwner for any Views directly added to the ComponentActivity .

reportFullyDrawn() backport - The Activity method of reportFullyDrawn() has been backported in ComponentActivity to work on all API levels, fixing a crash on API 19 and adding tracing for this method for all API levels.

The createIntent() method of ActivityResultContact now takes a Context in addition to the input to make it possible to create explicit Intents. ( aosp/1238800 )
An ActivityResultContract can now override getSynchronousResult() to deliver a result without calling startActivityForResult . This is used by the RequestPermission and RequestPermissions contracts to correctly deliver a 'granted' status if the requested permissions are already granted. ( b/151110799 )
The previously available Dial contract has been removed as that Intent is not meant to be used with startActivityForResult() . ( aosp/1266916 )

৫ সেপ্টেম্বর, ২০১৯

androidx.activity:activity:1.0.0 and androidx.activity:activity-ktx:1.0.0 are released. The commits included in this version can be found here .

Major Features of 1.0.0

ComponentActivity : ComponentActivity serves as the new base class for FragmentActivity in Fragment 1.1.0 and, by extension, AppCompatActivity in AppCompat 1.1.0 .
activity-ktx : The activity-ktx module includes a by viewModels Kotlin property extension for accessing ViewModels. This module is automatically included when you include fragment-ktx from Fragment 1.1.0 .
OnBackPressedDispatcher : As a composable alternative to overriding onBackPressed() , you can now register a OnBackPressedCallback from any LifecycleOwner (such as a fragment) to intercept system back button events. A lambda with receiver version addCallback has been added to activity-ktx . See Provide custom back navigation documentation for more details.
onRetainCustomNonConfigurationInstance deprecation : the onRetainCustomNonConfigurationInstance() and the related getLastCustomNonConfigurationInstance() APIs have been deprecated. It is strongly recommended to use ViewModels to store non-configuration state as they offer a composable solution suitable for any ViewModelStoreOwner that makes the ownership of the retained objects clear and provides an onCleared() callback for cleaning up resources when the activity is finally destroyed.

Methods to add a new OnBackPressedCallback to the OnBackPressedDispatcher now return a Cancellable object, allowing removal of the callback without requiring an explicit reference to the OnBackPressedDispatcher . ( aosp/922523 )
Adding a OnBackPressedCallback with an associated LifecycleOwner now results in adding and removing the OnBackPressedCallback as the Lifecycle is started and stopped, respectively. ( aosp/922523 )
