Activity: v1.6.1

October 24, 2022

androidx.activity:activity:1.6.1, androidx.activity:activity-compose:1.6.1, and androidx.activity:activity-ktx:1.6.1 are released. Version 1.6.1 contains these commits.

Bug Fixes

• Fixed an issue with the PickMultipleVisualMedia Activity Result contract not launching on Android R devices when using the default value for maxItems. (Ie2776, b/249182130)

Activity: v1.7.0-alpha02

October 24, 2022

androidx.activity:activity:1.7.0-alpha02, androidx.activity:activity-compose:1.7.0-alpha02, and androidx.activity:activity-ktx:1.7.0-alpha02 are released. Version 1.7.0-alpha02 contains these commits.

Bug Fixes

• From Activity 1.6.1: Fixed an issue with the PickMultipleVisualMedia Activity Result contract not launching on Android R devices when using the default value for maxItems. (Ie2776, b/249182130)

Benchmark: v1.2.0-alpha06

October 24, 2022

androidx.benchmark:benchmark-*:1.2.0-alpha06 is released. Version 1.2.0-alpha06 contains these commits.

API Changes

• BaselineProfileRule no longer requires root on Android 13 (API 33), and is no longer experimental. (Ie0a7d, b/250083467, b/253094958)
  • This change also fixes how profiles from an app are flushed to disk on unrooted devices, but requires updating the target app's profileinstaller dependency.
  • To use BaselineProfileRule or CompilationMode.Partial(warmupIterations) on an unrooted device, you must also update your target app to use androidx.profileinstaller.profileinstaller:1.3.0-alpha01. This enables flushing the profile to disk correctly, so that it can be compiled/extracted.

Bug Fixes

• Fixes SampledProfiling crash on API 33+. (I40743, b/236109374)

Browser: v1.5.0-alpha01

October 24, 2022

androidx.browser:browser:1.5.0-alpha01 is released. Version 1.5.0-alpha01 contains these commits.

New Features

• Added CustomTabsIntent.Builder#setInitialActivityHeightPx, which allows developers to specify the initial launch height of a Custom Tab, and optionally the resize behavior (fixed or resizable). (I48bd3)
• Added CustomTabsIntent.Builder#setToolbarCornerRadiusDp which allows developers to specify the toolbar's top corner radius. (I48bd3)
• Added CustomTabsIntent.Builder#setCloseButtonPosition which allows developers to set the position of the close button on the toolbar. (I48bd3)
• Added an onActivityResized callback method to interface CustomTabsCallback to let developers know when a Custom Tab is resized (expanded to full height or minimized back down to initial launch height). (Id99ce)
• Populates the current app's language in Accept-Language by default to align to Android’s per-app language experience. (I3d1d7)

API Changes

• Added @RequiresPermission to APIs that require granting the POST_NOTIFICATIONS permission on SDK 33 and above. This was developed in an internal branch. b/238790278 for reference.

October 24, 2022

Bug Fixes

• Fixed Samsung J7 Prime (SM-G610M) and J7 (SM-J710MN) Preview/VideoCapture stretched issue on API level 27 devices. Resolution 1920x1080 causes the Preview/VideoCapture images to be stretched. Added workaround to not select the 1920x1080 resolution for Preview or VideoCapture to avoid the image stretched problem. (I0e04e)
• Fixed low framerate when using VideoCapture and Preview use cases with 16:9 aspect ratio on some Huawei devices. (If8c88, b/223643510)
• Fixed camera open failure when Preview's SurfaceProvider is not set. As part of the fix, Preview with no SurfaceProvider set will now not be configured into the camera capture session. (I99681)

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.

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

• 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.

2022-09-21

Activity: v1.6.0

September 21, 2022

androidx.activity:activity:1.6.0, androidx.activity:activity-compose:1.6.0, and androidx.activity:activity-ktx:1.6.0 are released. Version 1.6.0 contains these commits.

Important changes since 1.5.0

• Added ActivityResultContracts.PickVisualMedia and ActivityResultContracts.PickMultipleVisualMedia for providing a backward compatible contract that uses MediaStore.ACTION_PICK_IMAGES when the Photo Picker is available and Intent.ACTION_OPEN_DOCUMENT when it is not available.
• Integrated the OnBackInvokedCallback in Android 13 into the OnBackPressedDispatchers provided by ComponentActivity and ComponentDialog. This ensures that all APIs built onOnBackPressedDispatcher work when enabling a predictive back gesture.

Benchmark: v1.2.0-alpha04

September 21, 2022

androidx.benchmark:benchmark-*:1.2.0-alpha04 is released. Version 1.2.0-alpha04 contains these commits.

New Features

• Add support for dryRunMode.enable instrumentation argument to macrobenchmark (already available in micro) for faster local development, and validating app automation (e.g. in presubmit). This overrides iterations to 1, skips compilation, suppresses all configuration errors, and disables measurement .json file output. (Ib51b4, b/175149857)

  On Gradle command line:

  ./gradlew macrobenchmark:cC -P android.testInstrumentationRunnerArguments.androidx.benchmark.dryRunMode.enable=true
  

  In build.gradle:

  android {
      defaultConfig {
          testInstrumentationRunnerArgument 'androidx.benchmark.dryRunMode.enable', 'true'
      }
  }
  

Bug Fixes

• Fixed StartupTimingMetric to no longer require measured Activities to be launched through MacrobenchmarkScope.startActivityAndWait(). This means the metric can pick up launches from e.g. notifications, Context.startActivity(), in-app Activity based navigation, or shell commands. (Ia2de6, b/245414235)
• Fix bug where startActivityAndWait would timeout trying to wait for launch completion on emulators by reducing strictness of frame detection. (Ibe2c6, b/244594339, b/228946895)

CameraX: v1.2.0-beta01

August 24, 2022

androidx.camera:camera-*:1.2.0-beta01 is released. Version 1.2.0-beta01 contains these commits.

New Features

• New library camera-mlkit-vision. Easily integrate CameraX with many MLKit features, including barcode scanning, face detection, text detection, etc. Please find the sample code here.
• New experimental Zero-Shutter Lag API. Optimizes capture pipeline to have better latency while keeping good image quality. When the capture mode is set to CAPTURE_MODE_ZERO_SHUTTER_LAG, the latency between the shutter button is clicked and the picture is taken is expected to be minimized, compared with other capture modes. On devices that don’t support ZERO_SHUTTER_LAG, it’ll fallback to CAPTURE_MODE_MINIMIZE_LATENCY.
• Made ImageAnalysis.Analyzer and MLKitAnalyzer as official APIs.
• Exposed API for setting location metadata to the saved video.
• Rename ImageAnalysis.Analyzer#getTargetResolutionOverride() to ImageAnalysis.Analyzer#getDefaultTargetResolution().

Bug Fixes

• Fixed Alps k61v1_basic_ref image capture issue. The captured JPEG images from HAL have incorrect Exif metadata. The Exif metadata doesn't have the 0xffd9 or 0xffda tag to make ExifInterface correctly parse the attributes. Capturing the images in YUV format and then compressing them to JPEG output images to workaround this issue. (I45abb)
