Version 1.0

Version 1.0.0-alpha16

May 20, 2025

androidx.privacysandbox.ui:ui-*:1.0.0-alpha16 is released. Version 1.0.0-alpha16 contains these commits.

New Features

  • Added logic to measure obstructions on SandboxedSdkView, which will be sent in SessionObserver.onUiContainerChanged() if SandboxedUiAdapterSignalOptions.OBSTRUCTIONS is included in the associated SessionObserverFactory.signalOptions. Obstructions are reported relative to the view itself.

API Changes

  • Moved SandboxedSdkUi from ui-client into a new ui-client-compose library.
  • Added logic to measure obstructions on UI containers. (I34bea)

Bug Fixes

  • Fixed SandboxedSdkView.setAlpha(), which now updates the alpha of its content view.

Version 1.0.0-alpha15

March 26, 2025

androidx.privacysandbox.ui:ui-client:1.0.0-alpha15, androidx.privacysandbox.ui:ui-core:1.0.0-alpha15, and androidx.privacysandbox.ui:ui-provider:1.0.0-alpha15 are released. Version 1.0.0-alpha15 contains these commits.

New Features

  • Set the default Z-ordering of SandboxedSdkView and SandboxedSdkUi to “below”, indicating that the provider’s surface is now placed below the client’s window. Added support for the UI provider to receive MotionEvents in this mode after being received by the client window.
  • Added a signalOptions field to the SessionObserverFactory interface. This can be used to define a set of String options which will be used to determine which signals are collected for the associated SessionObserver. The initial set of signals is defined in SandboxedUiAdapterSignalOptions. If no signal options are set, only SessionObserver.onSessionOpened() and SessionObserver.onSessionClosed() will be called.

API Changes

  • Renamed SessionConstants to SessionData in SandboxedUiAdapter.openSession().

Known Issues

  • When the SDK is loaded in the SDK Runtime and the Z-order of SandboxedSdkView or SandboxedSdkUi is “above”, the gesture is exclusively received by the provider window and not transferred to the client window anymore.

Version 1.0.0-alpha14

February 26, 2025

androidx.privacysandbox.ui:ui-client:1.0.0-alpha14, androidx.privacysandbox.ui:ui-core:1.0.0-alpha14, and androidx.privacysandbox.ui:ui-provider:1.0.0-alpha14 are released. Version 1.0.0-alpha14 contains these commits.

New Features

  • You can now create ‘shared UI’, i.e. UI that can have elements that are client-owned and provider-owned. Shared UI can be hosted using SharedUiContainer, which extends ViewGroup. New APIs utilize the concept of session management similar to that of SandboxedSdkView and SandboxedUiAdapter.
  • All APIs added in this release are behind the SharedUiPresentationApi @RequiresOptIn flag.

API Changes

  • Added session management and asset registration APIs to SharedUiContainer. Session management is implemented using SharedUiAdapter introduced in the same release. (Ic60b0)
  • Added SharedUiContainer that can host client-owned and provider-owned UI. It places all of its child views in the top left corner. (Ia7310)
  • Added backwards compatibility support for SharedUiAdapter. (I56d7a)
  • Added SharedUiAdapter for session management of View containers that can host client-owned and provider-owned UI. Session management logic is similar to that of SandboxedUiAdapter. (I501f6)

Bug Fixes

  • Compute viewability when onVisibilityAggregated is called. (I91c69)

Known Issues

  • When placed inside a PoolingContainer, SharedUiContainer closes the session on window detachment.

Version 1.0.0-alpha13

January 29, 2025

androidx.privacysandbox.ui:ui-client:1.0.0-alpha13, androidx.privacysandbox.ui:ui-core:1.0.0-alpha13, and androidx.privacysandbox.ui:ui-provider:1.0.0-alpha13 are released. Version 1.0.0-alpha13 contains these commits.

New Features

  • Added a Composable object called SandboxedSdkUi which can be used to display remote content within a Compose UI. This object utilizes existing SandboxedSdkView concepts for session management and event listeners. (I009cf)
  • Changed the SandboxedUiAdapter.openSession signature to include a new SessionConstants parameter which replaces the previous windowInputToken. This parameter is to be used to pass values which will be constant for the lifetime of the SandboxedUiAdapter.Session. (Ibc0df, I28435)

Known Issues

  • SessionObserver events are not sent for SandboxedSdkUi when it is scrolled.
  • SandboxedSdkUi is not clipped by parent views when it is in Z-above mode.

API Changes

  • Remove deprecated SDKActivityLauncher code (I49a4f)
  • Separated observer factory registration logic from SandboxedUiAdapter by adding a new SessionObserverFactoryRegistry interface. (I245cc)

Version 1.0.0-alpha12

December 11, 2024

androidx.privacysandbox.ui:ui-client:1.0.0-alpha12, androidx.privacysandbox.ui:ui-core:1.0.0-alpha12, and androidx.privacysandbox.ui:ui-provider:1.0.0-alpha12 are released. Version 1.0.0-alpha12 contains these commits.

New Features

  • Replaced StateChangedListener with SandboxedSdkViewEventListener. This event listener can be used to listen to UI displayed, session closed and session error events.

API Changes

  • Adds SandboxedSdkViewEventListener for listening to UI events inside SandboxedSdkView. This version also removes StateChangedListener. (Id71ea)

Bug Fixes

  • Removed clipping bounds logic from SandboxedSdkView. This will cause UX issues if SandboxedSdkView is placed in a scrollable container and orderProviderUiAboveClientUi(false) has not been called (until the underlying framework bug is fixed). (Id420d)
  • Fixed RemoteException that could occur if the remote process dies while using DelegatingSandboxedUiAdapter.

Version 1.0.0-alpha11

November 13, 2024

androidx.privacysandbox.ui:ui-client:1.0.0-alpha11, androidx.privacysandbox.ui:ui-core:1.0.0-alpha11, and androidx.privacysandbox.ui:ui-provider:1.0.0-alpha11 are released. Version 1.0.0-alpha11 contains these commits.

New Features

  • Introduced an experimental API, DelegatingSandboxedUiAdapter, which extends SandboxedUiAdapter and can be used to delegate between different SandboxedUiAdapters. When this adapter is set on a client container such as SandboxedSdkView, the delegating adapter can change the delegate adapter using updateDelegate. This will close the existing session and create a new SandboxedUiAdapter.Session for the new delegate. This allows for seamless transitions between delegates. (I5f1c5, I9e3e7)
  • Added better SandboxedSdkView support for padding. (Ic414f)

Bug Fixes

  • Fixed NullPointerException that could occur on a global layout event.

Version 1.0.0-alpha10

September 18, 2024

androidx.privacysandbox.ui:ui-client:1.0.0-alpha10, androidx.privacysandbox.ui:ui-core:1.0.0-alpha10, and androidx.privacysandbox.ui:ui-provider:1.0.0-alpha10 are released. Version 1.0.0-alpha10 contains these commits.

New Features

  • Updated session opening logic to only open a session inside a SandboxedSdkView if the window containing the SandboxedSdkView is visible.
  • Updated SessionObserver logic to send onUiContainerChanged when the visibility of the window containing the SandboxedSdkView changes.

Bug Fixes

  • Invoke onUiContainerChanged when the window visibility changes (I541cf)
  • Removed manual outlining of access to new platform APIs since this happens automatically via API modeling when using R8 with AGP 7.3 or later (e.g. R8 version 3.3) and for all builds when using AGP 8.1 or later (e.g. D8 version 8.1). Clients who are not using AGP are advised to update to D8 version 8.1 or later. See this article for more details. (If6b4c, b/345472586)

Version 1.0.0-alpha09

June 26, 2024

androidx.privacysandbox.ui:ui-client:1.0.0-alpha09, androidx.privacysandbox.ui:ui-core:1.0.0-alpha09, and androidx.privacysandbox.ui:ui-provider:1.0.0-alpha09 are released. Version 1.0.0-alpha09 contains these commits.

New Features

  • Introduced AbstractSandboxedUiAdapter and AbstractSandboxedUiAdapter.AbstractSession abstract classes that can be used by UI providers to avoid implementing the entire SandboxedUiAdapter or Session interfaces. It is recommended for UI providers to use these abstract classes.
  • Added registerObserverFactory logic that allows a SessionObserverFactory to be attached to a SandboxedUiAdapter. When a SessionObserverFactory is attached to an adapter, a SessionObserver will be created for each new UI session created for that adapter. The created SessionObserver will receive an onSessionOpened callback when the UI session is opened. When the UI presentation of the Session’s view changes, SessionObserver.onUiContainerChanged will be called. onUiContainerChanged is throttled and will be called at most every 200ms.
  • Added SandboxedSdkViewUiInfo which can be created from the Bundle sent in SessionObserver.onUiContainerChanged. This object represents the UI state of the SandboxedSdkView that is hosting the UI session. It contains height and width information, a Rect representing the geometry of the view that is visible on screen, and an opacity hint that represents the opacity of the view.

API Changes

  • Add opacity hint to SandboxedSdkViewUiInfo. (I093ac)
  • Add SessionObserver.onUiContainerChanged and SandboxedSdkViewUiInfo. (Ie98bc)
  • Add SessionObserver interface and registration logic. (I047dc)
  • Add AbstractSandboxedUiAdapter and AbstractSession. (I3617a)

Known Issues

  • When the UI provider is in the same process as the client application, SessionObserver.onUiContainerChanged is not sent when the container scrolls.

Version 1.0.0-alpha08

May 14, 2024

androidx.privacysandbox.ui:ui-client:1.0.0-alpha08, androidx.privacysandbox.ui:ui-core:1.0.0-alpha08, and androidx.privacysandbox.ui:ui-provider:1.0.0-alpha08 are released. Version 1.0.0-alpha08 contains these commits.

New Features

  • Added support for using SandboxedSdkView inside a PoolingContainer such as a RecyclerView. When a SandboxedSdkView has a parent that is a PoolingContainer, the lifecycle of its UI sessions will be aligned with that of the PoolingContainer to ensure that the session can persist through window detachment.

API Changes

  • Deprecated Privacy Sandbox Activity APIs. These APIs can now be found in the dedicated Activity library androidx.privacysandbox.activity instead. (I68beb)

Bug Fixes

  • Fixed rendering bug when displaying remote content inside pooling containers. (I804df)
  • Fixed a bug that caused rendering issues for ViewGroups in backwards compatibility mode. (I8de92)
  • When one of SandboxedSdkView's parents is a PoolingContainer, close the UI Session when the PoolingContainer indicates resources can be released, instead of on window detachment. (I2046b)

External Contribution

  • GestureDetectorCompat is now deprecated as GestureDetector is available from the minSdk. (Icc4cd)

Version 1.0.0-alpha07

October 18, 2023

androidx.privacysandbox.ui:ui-client:1.0.0-alpha07, androidx.privacysandbox.ui:ui-core:1.0.0-alpha07, and androidx.privacysandbox.ui:ui-provider:1.0.0-alpha07 are released. Version 1.0.0-alpha07 contains these commits.

New Features

  • Added backwards compatibility support for the library. On API 33 and below, the provider’s view will be rendered inside the app process, in a different classloader. (If0b7a)
  • Added logic that allows the resizing of host and provider containers to be committed in the same frame to avoid visible UI jank. (Ic2cd9)

API Changes

  • MinSdk for the library bumped to API 21. (I474b8)

Version 1.0.0-alpha06

September 20, 2023

androidx.privacysandbox.ui:ui-client:1.0.0-alpha06, androidx.privacysandbox.ui:ui-core:1.0.0-alpha06, and androidx.privacysandbox.ui:ui-provider:1.0.0-alpha06 are released. Version 1.0.0-alpha06 contains these commits.

New Features

  • Added logic to clip SandboxedSdkView to the “bounding parent” View that it may scroll within. This ensures that the contents of the SandboxedSdkView do not occlude other views or any UI components outside of the root content view. (I9ea94)

API Changes

  • Rename SandboxedSdkView.setZOrderOnTopAndEnableUserInteraction to orderProviderUiAboveClientUi (Iecb7e)

Bug Fixes

  • Send the correct Z-order value to the host. (Ib0ddf)
  • Only transfer touch focus for vertical scrolls/flings. (I0528c)

Version 1.0.0-alpha05

August 9, 2023

androidx.privacysandbox.ui:ui-client:1.0.0-alpha05, androidx.privacysandbox.ui:ui-core:1.0.0-alpha05, and androidx.privacysandbox.ui:ui-provider:1.0.0-alpha05 are released. Version 1.0.0-alpha05 contains these commits.

New Features

  • Added logic to transfer touch focus to host on scroll and fling gestures originating from SandboxedSdkView. This allows the client’s scrollable container hosting provider UI to respond correctly to scrolls and flings.

API Changes

  • Added windowInputToken parameter to SandboxedUiAdapter (Ief578)

Bug Fixes

  • Set session state to Active after the first draw (I36f3f)
  • Fix layout issue with SandboxedSdkView. (I09cb8)
  • Added logic to transfer touch focus to host. (I33b54)
  • Add windowInputToken parameter to SandboxedUiAdapter. This is necessary to ensure that the SurfaceControlViewHost's token is correctly associated with the host of the embedded hierarchy. (Ief578)
  • Run notifyResized inside the main thread. (I62440)
  • Fix crash in the Session.close() flow. (I5392e)

Version 1.0.0-alpha04

New Features

  • Introduce the SdkActivityLauncher. An interface for allowing runtime enabled SDKs to launch activities. (I5b3dc)

Bug Fixes

  • Fix notifyZOrderChanged race condition. Ensures that the UI provider is notified for all Z-order changes. The UI provider will not be explicitly notified if the Z-order of the SandboxedSdkView is changed before openSession is invoked.

Version 1.0.0-alpha03

May 24, 2023

androidx.privacysandbox.ui:ui-client:1.0.0-alpha03, androidx.privacysandbox.ui:ui-core:1.0.0-alpha03, and androidx.privacysandbox.ui:ui-provider:1.0.0-alpha03 are released. Version 1.0.0-alpha03 contains these commits.

New Features

  • StateChangedListener informs the application of changes in the UI session

API Changes

  • Added StateChangedListener to replace the ErrorConsumer (Icd5d3)

Bug Fixes

  • Fixed notifyZOrderChanged race condition so the UI provider is notified for all Z-order changes
