Media3: v1.5.0

November 27, 2024

androidx.media3:media3-*:1.5.0 is released. Version 1.5.0 contains these commits.

• Common Library:
  • Add ForwardingSimpleBasePlayer that allows forwarding to another player with small adjustments while ensuring full consistency and listener handling (#1183).
  • Replace SimpleBasePlayer.State.playlist by getPlaylist() method.
  • Add override for SimpleBasePlayer.State.Builder.setPlaylist() to directly specify a Timeline and current Tracks and Metadata instead of building a playlist structure.
  • Increase minSdk to 21 (Android Lollipop). This is aligned with all other AndroidX libraries.
  • Add androidx.media3:media3-common-ktx artifact which provides Kotlin-specific functionality built on top of the Common library
  • Add Player.listen suspending extension function to spin a coroutine to listen to Player.Events to the media3-common-ktx library.
  • Remove @DoNotInline annotations from manually out-of-lined inner classes designed to avoid runtime class verification failures. Recent versions of R8 now automatically out-of-line calls like these to avoid the runtime failures (so the manual out-of-lining is no longer required). All Gradle users of the library must already be a using a version of the Android Gradle Plugin that uses a version of R8 which does this, due to compileSdk = 35. Users of the library with non-Gradle build systems will need to ensure their R8-equivalent shrinking/obfuscating step does a similar automatic out-of-lining process in order to avoid runtime class verification failures. This change has already been done in other AndroidX libraries.
• ExoPlayer:
  • MediaCodecRenderer.onProcessedStreamChange() can now be called for every media item. Previously it was not called for the first one. Use MediaCodecRenderer.experimentalEnableProcessedStreamChangedAtStart() to enable this.
  • Add PreloadMediaSource.PreloadControl.onPreloadError to allow PreloadMediaSource.PreloadControl implementations to take actions when error occurs.
  • Add BasePreloadManager.Listener to propagate preload events to apps.
  • Allow changing SNTP client timeout and retry alternative addresses on timeout (#1540).
  • Remove MediaCodecAdapter.Configuration.flags as the field was always zero.
  • Allow the user to select the built-in speaker for playback on Wear OS API 35+ (where the device advertises support for this).
  • Defer the blocking call to Context.getSystemService(Context.AUDIO_SERVICE) until audio focus handling is enabled. This ensures the blocking call isn't done if audio focus handling is not enabled (#1616).
  • Allow playback regardless of buffered duration when loading fails (#1571).
  • Add AnalyticsListener.onRendererReadyChanged() to signal when individual renderers allow playback to be ready.
  • Fix MediaCodec.CryptoException sometimes being reported as an "unexpected runtime error" when MediaCodec is operated in asynchronous mode (default behaviour on API 31+).
  • Pass bufferedDurationUs instead of bufferedPositionUs with PreloadMediaSource.PreloadControl.onContinueLoadingRequested(). Also changes DefaultPreloadManager.Status.STAGE_LOADED_TO_POSITION_MS to DefaultPreloadManager.Status.STAGE_LOADED_FOR_DURATION_MS, apps then need to pass a value representing a specific duration from the default start position for which the corresponding media source has to be preloaded with this IntDef, instead of a position.
  • Add ForwardingRenderer implementation that forwards all method calls to another renderer (1703).
  • Add playlist preloading for the next item in the playlist. Apps can enable preloading by calling ExoPlayer.setPreloadConfiguration(PreloadConfiguration) accordingly. By default preloading is disabled. When opted-in and to not interfere with playback, DefaultLoadControl restricts preloading to start and continue only when the player is not loading for playback. Apps can change this behaviour by implementing LoadControl.shouldContinuePreloading() accordingly (like when overriding this method in DefaultLoadControl). The default implementation of LoadControl disables preloading in case an app is using a custom implementation of LoadControl.
  • Add method MediaSourceEventListener.EventDispatcher.dispatchEvent() to allow invoking events of subclass listeners (1736).
  • Add DefaultPreloadManager.Builder that builds the DefaultPreloadManager and ExoPlayer instances with consistently shared configurations.
  • Remove Renderer[] parameter from LoadControl.onTracksSelected() as DefaultLoadControl implementation can retrieve the stream types from ExoTrackSelection[].
  • Deprecated DefaultLoadControl.calculateTargetBufferBytes(Renderer[], ExoTrackSelection[]) and marked method as final to prevent overrides. The new DefaultLoadControl.calculateTargetBufferBytes(ExoTrackSelection[]) should be used instead.
  • Report MediaSourceEventListener events from secondary sources in MergingMediaSource. This will result in load start/error/cancelled/completed events being reported for sideloaded subtitles (those added with MediaItem.LocalConfiguration.subtitleConfigurations), which may appear as duplicate load events emitted from AnalyticsListener.
  • Prevent subtitle & metadata errors from completely stopping playback. Instead the problematic track is disabled and playback of the remaining tracks continues (#1722).
    • In new subtitle handling (during extraction), associated parse (e.g. invalid subtitle data) and load errors (e.g. HTTP 404) are emitted via onLoadError callbacks.
    • In legacy subtitle handling (during rendering), only associated load errors are emitted via onLoadError callbacks while parse errors are silently ignored (this is pre-existing behaviour).
  • Fix bug where playlist items or periods in multi-period DASH streams with durations that don't match the actual content could cause frame freezes at the end of the item (#1698).
  • Add a setter to SntpClient to set the max elapsed time since the last update after which the client is re-initialized (#1794).
• Transformer:
  • Add SurfaceAssetLoader, which supports queueing video data to Transformer via a Surface.
  • ImageAssetLoader reports unsupported input via AssetLoader.onError instead of throwing an IllegalStateException.
  • Make setting the image duration using MediaItem.Builder.setImageDurationMs mandatory for image export.
  • Add export support for gaps...

Activity: v1.10.0-beta01

November 13, 2024

androidx.activity:activity:1.10.0-beta01, androidx.activity:activity-compose:1.10.0-beta01, and androidx.activity:activity-ktx:1.10.0-beta01 are released with no changes since the last alpha. Version 1.10.0-beta01 contains these commits.

Benchmark: v1.4.0-alpha05

November 13, 2024

androidx.benchmark:benchmark-*:1.4.0-alpha05 is released. Version 1.4.0-alpha05 contains these commits.

Bug Fixes

• Fixed an issue on API 34+ where CompilationMode.None() would have inconsistent performance not representative of initial, worst case performance. This works around a platform change which allows ART's compilation state verify to partially compile apps (only affecting class loading) shortly after first launch. (Ie48d0)
• Fixed issue where (especially short) traces could be captured that wouldn't report measurement from built-in Macrobenchmark Metrics, due to the process name being truncated within the Perfetto trace. Now macrobenchmark works around this issue by looking for the truncated package name in all built-in queries, in addition to the expected package name. Note that custom TraceMetric implementations or other direct callers of PerfettoSession.query can implement this same behavior by changing process.name LIKE "$packageName" in a Perfetto query to instead be (process.name LIKE "$packageName" OR process.name LIKE "$(packageName.takeLast(15))"). (I5bf01, b/377565760)

Car App: v1.7.0-beta03

November 13, 2024

Fixed a security vulnerability and other general bug fixes. If you are using a lower version, please update to use this version.

API Changes

• Update CAL Serialization / De-serialization code to only handle objects which have the annotation @CarProtocol declared on them. (Ic730e)
• CarAppExtender can now be used to extend the framework Notification.Builder instead of only NotificationCompat.Builder. (Id3ad7)
• Add KEY_EXCLUDE_MEDIA_ITEM_FROM_MIXED_APP_LIST extra. (I201f9)
• Deprecate the empty Builder constructor on ConversationItem and replace it with a constructor that takes required parameters. Also adds a check to guard against null messages. (Ic8221)

Bug Fixes

• Ensure PlaceList map uses string (Text-only) Header title. (Ic992f)
• This library now uses JSpecify nullness annotations, which are type-use. Kotlin developers should use the following compiler arguments to enforce correct usage: -Xjspecify-annotations=strict, -Xtype-enhancement-improvements-strict-mode. (Ib5367, b/326456246)

Collection: v1.5.0-alpha06

API Changes

• Adds stylusHoverIcon modifier. (Iff20a, b/331289114)
• Deprecated AnchoredDraggableState's confirmValueChange. Instead of vetoing state changes, disallowed anchors should not be in the active anchor set, and an OverscrollEffect should be used to indicate the unavailability of the requested action. (Ia717f)
• Changes Autofill manager to be an interface. (I84914, b/376080755)
• Adds OverscrollEffect#withoutDrawing and OverscrollEffect#withoutEventHandling APIs - these APIs create a wrapped instance of the provided overscroll effect that doesn't draw / handle events respectively, which allows for rendering overscroll in a separate component from the component that is dispatching events. For example, disabling drawing the overscroll inside a lazy list, and then drawing the overscroll separately on top / elsewhere. (Idbb3d, b/266550551, b/204650733, b/255554340, b/229537244)
• Adding autofill support in text toolbar. (Ie6a4c)

API Changes

• Added a new LocalActivity composition local that provides the Activity for the current scope, removing the need for developers to get an Activity from the LocalContext. It also comes with a new lint rule that checks when the LocalContext is incorrectly being cast to an Activity. (I7746a, b/283009666)

Bug Fixes

• From Activity 1.9.3: PredictiveBackHandler will no longer fire it's callback after the handler has been disabled. This will fix an issue where the NavHost from Navigation Compose would throw an IndexOutOfBoundsException. (I3f75e, b/365027664, b/340202286)

Dependency Update

• Activity Compose now depends on Compose Runtime 1.7.0 (I7746a, b/283009666)

Bug Fixes

• isProfileable is now always overridden in benchmark builds, and isDebuggable is also now always overridden in both benchmark and nonMinified (baseline profile capture) builds. (I487fa, b/369213505)
• Fixes compilation detection on some physical devices prior to API 28 - affects json context.compilationMode, as well as behavior of androidx.benchmark.requireAot=true (which no longer incorrectly throws) (Ic3e08, b/374362482)
• In CpuEventCounter metrics, throw if invalid measurements are observed (e.g. instructions/cpucycles==0) (I8c503)

Camera: v1.4.0

Camera: v1.5.0-alpha03

October 30, 2024

androidx.camera:camera-*:1.5.0-alpha03 is released. Version 1.5.0-alpha03 contains these commits.

API Changes

• Add output format APIs for RAW and RAW + JPEG ImageCapture, the device capability check is exposed in ImageCaptureCapabilities#getSupportedOutputFormats. The OUTPUT_FORMAT_RAW is to capture RAW image, which is Adobe DNG format and OUTPUT_FORMAT_RAW_JPEG is to simultaneously capture RAW and JPEG images. The new ImageCapture#takePicture API is used for simultaneous image capture, it needs to provide two OutputFileOptions, the first one is for RAW image and the second one is for JPEG image. (Ib0f3d)

Bug Fixes

• Fixed preview and video under-exposure issue on TCL devices when VideoCapture is enabled. (Id7a64)
• Fixed the issue where invoking startFocusMetering with PreviewView.getMeteringPointFactory doesn't get the correct sensor coordinates when an effect is enabled or when 4 use cases are bound (stream-sharing). (I916c5, b/345993685)
• Fixed the VideoRecordEvent.Finalize.ERROR_INSUFFICIENT_STORAGE event is not triggered when recording a video and there is insufficient storage space available. (I35779, b/356399842)

Camera: v1.5.0-alpha03

October 30, 2024

androidx.camera:camera-*:1.5.0-alpha03 is released. Version 1.5.0-alpha03 contains these commits.

API Changes

• Add output format APIs for RAW and RAW + JPEG ImageCapture, the device capability check is exposed in ImageCaptureCapabilities#getSupportedOutputFormats. The OUTPUT_FORMAT_RAW is to capture RAW image, which is Adobe DNG format and OUTPUT_FORMAT_RAW_JPEG is to simultaneously capture RAW and JPEG images. The new ImageCapture#takePicture API is used for simultaneous image capture, it needs to provide two OutputFileOptions, the first one is for RAW image and the second one is for JPEG image. (Ib0f3d)

Bug Fixes

• Fixed preview and video under-exposure issue on TCL devices when VideoCapture is enabled. (Id7a64)
• Fixed the issue where invoking startFocusMetering with PreviewView.getMeteringPointFactory doesn't get the correct sensor coordinates when an effect is enabled or when 4 use cases are bound (stream-sharing). (I916c5, b/345993685)
• Fixed the VideoRecordEvent.Finalize.ERROR_INSUFFICIENT_STORAGE event is not triggered when recording a video and there is insufficient storage space available. (I35779, b/356399842)

• Add coefficientOfVariation to Benchmark JSON output to show stability within a given benchmark run. (Ib14ea)

Bug Fixes

• Fixed CollectBaselineProfileTask when AVD device has spaces in it. (Ia0225, b/371642809)
• Speculative fix for errors from StartupMode.COLD exceptions: Package <packagename> must not be running prior to cold start!. Now, MacrobenchmarkScope.killProcess() (including the one run before each iteration, used to implement StartupMode.COLD behavior) will wait to verify that the app's processes have all stopped running. (I60aa6, b/351582215)
• Fixed issue where UNLOCKED_ error would show up on some rooted emulators. (Ic5117)
• This library now uses JSpecify nullness annotations, which are type-use. Kotlin developers should use the following compiler arguments to enforce correct usage: -Xjspecify-annotations=strict, -Xtype-enhancement-improvements-strict-mode (I7104f, b/326456246)

Benchmark: v1.3.2

October 2, 2024

androidx.benchmark:benchmark-*:1.3.2 is released. Version 1.3.2 contains these commits.

Bug Fixes

• Fixed Firebase Test Lab (FTL) being unable to pull Baseline Profile or Macrobenchmark result files from the Baseline Profile Gradle Plugin. (I2f678, b/285187547)

To use FTL apply the plugin to the baseline profile module in the plugin block, with:

  plugins {
      ...
      id("com.google.firebase.testlab")
  }

and then configure firebase test lab with:

  firebaseTestLab {
  // Credentials for FTL service
  serviceAccountCredentials.set(file("credentials.json"))

  // Creates one or more managed devices to run the tests on.
  managedDevices {
      "ftlDeviceShiba34" {
          device = "shiba"
          apiLevel = 34
      }
  }

  // Ensures the baseline profile is pulled from the device.
  // Note that this will be automated as well later with aosp/3272935.
  testOptions {
      results {
          directoriesToPull.addAll("/storage/emulated/0/Android/media/${android.namespace}")
      }
  }

}

Also the created FTL device needs to be added to the baseline profile extension:

  baselineProfile {
      managedDevices += "ftlDeviceShiba34"
      useConnectedDevices = false
  }

Benchmark: v1.4.0-alpha02

October 2, 2024

androidx.benchmark:benchmark-*:1.4.0-alpha02 is released. Version 1.4.0-alpha02 contains these commits.

API Changes

• Moved Gradle tasks lockClocks and unlockClocks to be on benchmark projects, instead of available at the top level. This change was necessary as there is unfortunately no way to register these as top level actions without breaking project isolation. (I02b8f, b/363325823)

Bug Fixes

• BaselineProfileRule now collects profiles for multi-process apps by signaling each running process at the end of the block to dump profiles. If a profile based compilation never successfully finds a process to broadcast to, the compilation will fail, as it's unexpected to have profile data within. Additionally, added an instrumentation argument to control dump wait duration: androidx.benchmark.saveProfileWaitMillis (I0f519, b/366231469)
• From Benchmark 1.3.2: Fixed Firebase Test Lab (FTL) being unable to pull Baseline Profile or Macrobenchmark result files from the Baseline Profile Gradle Plugin. (I2f678, b/285187547)

To use FTL apply the plugin to the baseline profile module in the plugin block, with:

  plugins {
      ...
      id("com.google.firebase.testlab")
  }

and then configure firebase test lab with:

  firebaseTestLab {
  // Credentials for FTL service
  serviceAccountCredentials.set(file("credentials.json"))

  // Creates one or more managed devices to run the tests on.
  managedDevices {
      "ftlDeviceShiba34" {
          device = "shiba"
          apiLevel = 34
      }
  }

  // Ensures the baseline profile is pulled from the device.
  // Note that this will be automated as well later with aosp/3272935.
  testOptions {
      results {
          directoriesToPull.addAll("/storage/emulated/0/Android/media/${android.namespace}")
      }
  }

}

Also the created FTL device needs to be added to the baseline profile extension:

  baselineProfile {
      managedDevices += "ftlDeviceShiba34"
      useConnectedDevices = false
  }

Camera: v1.4.0-rc03

October 2, 2024

androidx.camera:camera-*:1.4.0-rc03 is released. Version 1.4.0-rc03 contains these commits.

Bug Fixes

• Added flash/torch/3A functionalities for image captures with CameraEffect. The image captures with CameraEffect should now have the same pre-capture and post-capture processings (e.g. flash trigger, 3A convergence etc. when applicable) as image capture without any CameraEffect. (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)

Camera: v1.5.0-alpha02

October 2, 2024

androidx.camera:camera-*:1.5.0-alpha02 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 the setTargetFrameRate or Camera2Interop API was always overwritten to the value provided by the AeFpsRangeLegacyQuirk. With this fix, CameraX library will respect the value set via the setTargetFrameRate or Camera2Interop API. (Ie2d32)
• Added flash/torch/3A functionalities for image captures with CameraEffect. The image captures with CameraEffect should now have the same pre-capture and post-capture processings (e.g. flash trigger, 3A convergence etc. when applicable) as image capture without any CameraEffect. (I5ff30)
• Excluded problematic output sizes for ImageAnalysis on Samsung SM-A057G device. When ImageAnalysis uses a resolution larger or equal to 1920x1440, it will cause black preview issue. Applied ExcludedSupportedSizesQuirk to the SM-A057G device to avoid the issue. (I63dfe,
