CameraX: v1.3.0-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 by VideoCapture 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 three MirrorMode, OFF, ON and ON_FRONT_ONLY. To align to the camera preview, it is recommended to use ON_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 and setTargetResolution API. Please use the new ResolutionSelector API instead. (I542c3)
• Added public APIs for concurrent dual camera, including
  1. List<List<CameraInfo>> getAvailableConcurrentCameraInfos()
  2. ConcurrentCamera bindToLifecycle(@NonNull ConcurrentCameraConfig concurrentCameraConfig)
  3. boolean isConcurrentCameraModeOn() and ConcurrentCameraConfig, SingleCameraConfig and ConcurrentCamera (Iab1c1)
• Make ImageProcessor.Response#getOutputImage NonNull (Ib9c60)
• Added VideoCapture mirroring APIs, including VideoCapture.Builder.setMirrorMode(int) and VideoCapture.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 the VideoCapture.Builder and getTargetFramerate() API in VideoCapture (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 contain AudioStats.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 in DefaultSurfaceProcessor. The crash could happen when VideoCapture is bound and the activity is paused. (Idb46a, b/273713906)

Activity: v1.7.0

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 (i.e., 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.

Dependency Updates

• Activity now depends on Lifecycle 2.6.1. (8fc31d)
• Activity now depends on ProfileInstaller 1.3.0. (83d3b1)

• 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 (i.e., 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.

Dependency Updates

• Activity now depends on Lifecycle 2.6.1. (8fc31d)
• Activity now depends on ProfileInstaller 1.3.0. (83d3b1)
