• Added Kotlin DSL camera2Interop extension blocks for preview, imageAnalysis, videoCapture, imageCapture, and SessionConfig.Builder, as well as CameraControl.applyCamera2InteropAsync extension function. (I51af9, b/529609261)
• Added new Camera2Interop configurator factory methods (forUseCase, forImageCapture, forSessionConfig, forCameraControl) and corresponding setInterop / applyInteropAsync methods on Preview.Builder, ImageCapture.Builder, ImageAnalysis.Builder, VideoCapture.Builder, SessionConfig.Builder, and CameraControl. (I0007b, b/529609261)

Media3: v1.11.0

August 05, 2026

• Common library:
  • Add Format.channelMask to explicitly represent the audio channel mask, and a new Util.getAudioTrackChannelConfig(Format) overload to safely resolve it.
  • Upgrade Kotlin from 2.0.20 to 2.2.0.
• ExoPlayer:
  • Fix a timing-dependent concurrency bug that could cause an IllegalStateException or IndexOutOfBoundsException in ExoPlayer.
  • Relax ad group count checks in AdsMediaSource to allow the ad group count to decrease when an ad group is fully processed (hasUnplayedAds() is false), accommodating dynamic ad group resizing during reset workflows.
  • Add getFlags() and FLAG_STRICT_DURATION to SampleStream to allow streams to report flags, and update renderers to check these flags dynamically.
  • Fall back to the frame rate estimator in MediaCodecVideoRenderer and to the codec output format in MediaCodecAudioRenderer to calculate the codec operating rate when the stream formats do not provide a valid value, and avoid unnecessary codec resets.
  • Remove clipping of content for client-side inserted ads in the core player. Instead, AdsMediaSource takes care of the clipping logic. Custom client-side inserted ads sources need to be updated to implement the content clipping internally.
  • Mark tracks with a well-formed but unrecognized codec profile or level as supported=NO_EXCEEDS_CAPABILITIES instead of supported=YES (which is how tracks with missing or malformed profile or level info are marked). This ensures these tracks (which are unlikely to be supported by the device) are not selected when there are better-supported alternatives.
  • Add DefaultPreloadManager.SimpleRankingDataComparator, which is a RankingDataComparator that compares the ranks of the media items based on their distances to the index of the current playing media item. Apps can override its compare(Integer, Integer) method if a more fine-tuned comparison logic is needed. The custom SimpleRankingDataComparator can be injected via a new constructor of DefaultPreloadManager.Builder.
  • Reduce the OOM risk of DefaultLoadControl.prioritizeTimeOverSizeThresholds by falling back to buffer byte size limits if available heap memory seems tight.
  • Align handling of still images when MediaItem.imageDurationUs is not set: JPEG and HEIC still images now 'play' with a very short default duration (the same way PNG and other images previously behaved).
  • Add MediaSource.prepareSource(MediaSourceCaller, PlayerId, BandwidthMeter) to plumb BandwidthMeter to MediaSource. The deprecated method with custom implementation will still be called by default though, it is recommended to implement the new method and use BandwidthMeter.getTransferListener() to get parity to the old method.
  • In DefaultBandwidthMeter, add support for a custom InitialBitrateSupplier. This allows apps to provide their own logic for determining the initial bitrate estimate, which will be used on creation of DefaultBandwidthMeter and on network type changes. The supplier can be set via DefaultBandwidthMeter.Builder.setInitialBitrateSupplier().
  • Enable dynamic scheduling by default. ExoPlayer playback work loop will run dynamically as opposed to on a static interval.
  • Remove an unnecessary reset that can occur when joining tracks with pre-roll samples to active playback.
  • In DefaultBandwidthMeter, optimize getInitialBitrateCountryGroupAssignment to return the country group assignments packed into a 32-bit integer instead of an array, reducing code size and avoiding allocations.
  • Fix AudioTrack initialization failures on some devices by ensuring the retry logic always attempts a minimum of 1 second buffer size if other retries (by halving the buffer size) are unsuccessful (#3207).
  • Fix codec issue on some devices where the codec was swallowing all samples if previously flushed before receiving input buffers.
  • Add experimental ExoPlayer.Builder.enablePerStreamMediaProgression() to allow advancing media processing on a per-stream basis. This reduces startup latency between playlist items and avoids playback becoming "stuck" with very short content (#3122).
  • Fix race condition related to audio session id usage where the initial audio session id auto-generated by ExoPlayer would be used instead of the value set by setAudioSessionId (#3241).
  • Add experimental HAGC (ST 2094-50) timed metadata playback support for progressive media (e.g. MP4, Matroska). The player automatically merges HAGC metadata tracks with the associated video track and delivers the metadata out-of-band to the decoder on API 37+ devices. This behavior can be disabled via DefaultMediaSourceFactory.setExperimentalEnableHagcPlayback(false).
  • Add Format.selectionPriority representing the relative preference of the Format in track selection (#3236).
  • Fix potential scrubbing mode issue where scrubbing could stall when seeking to 'end of stream'.
• CompositionPlayer:
  • Fix an issue where TrackSelector instances were not being released.
• Transformer:
  • Fix an issue where ExportResult.fileSizeBytes may be over-reported.
• Track selection:
  • Expose BaseTrackSelection.DEFAULT_FORMAT_COMPARATOR and add AdaptiveTrackSelection.Factory.setTrackFormatComparator to allow custom format ordering and ABR selection priority beyond bitrate-only ordering.
  • Fix a timing-dependent concurrency issue where rapid sequential updates to track selection parameters could result in some updates being lost or overwritten.
• Extractors:
  • MP4, MP3, and FLAC: Add FLAG_DISABLE_ARTWORK_METADATA to allow discarding attached pictures and cover art metadata during container parsing to reduce runtime memory consumption (#2077). This can also be enabled centrally via DefaultExtractorsFactory.setDisableArtworkMetadata.
  • MP4: Add support for extracting ITU-T T.35 (it35) timed metadata tracks.
  • MP4: Add support for extracting chapter metadata (both Nero and QuickTime formats). QuickTime chapters are preferred if both are present. The extracted chapter information is exposed as Chapter entries within the track's Metadata, allowing for native chapter navigation in MP4, M4A, and M4B files (such as audiobooks and podcasts) (#2803).
  • WAV, Matroska, and MP4: Add support for 64-bit floating point PCM audio (#3090).
  • Matroska: Use codec bitstream metadata to populate accurate ColorInfo.
  • MP4: Add support for seeking in fragmented MP4 files using the mfra box when a sidx box is not present. To enable this, provide FLAG_READ_MFRA_FOR_SEEK_MAP to the FragmentedMp4Extractor, which is now done by default in DefaultExtractorsFactory (#3088).
  • Ignore av1C data with unsupported version.
  • MP4: Add support for big-endian floating point PCM in fpcm boxes.
  • Matroska: Parse chapter info to Chapter entries in a track's Metadata

Compose Material3: v1.5.0-alpha24

July 15, 2026

androidx.compose.material3:material3-*:1.5.0-alpha24 is released. Version 1.5.0-alpha24 contains these commits.

Features

• Add new scroll variant for expressive TimePicker (I46f6b)
• Added a new material3-ripple library (I1b3a3), which adds support for drawing ripples that visually display focus using inset focus rings instead of an opacity layer. This new library acts as a replacement for material-ripple, and expected usage is similar:
  • If you are using material3 itself, use the built-in material3 ripple configuration that integrates with the theme and uses material3-ripple internally as an implementation detail.
  • If you were using material-ripple directly or want to support inset focus rings without depending on material3, use the new material3-ripple library directly.

API Changes

• Changed scrollbar ScrollIndicatorState parameter to be non-nullable. (Iab7c7, b/529445739)
• Re-add @ExperimentalMaterial3Api annotation to AppBarWithSearch APIs. (I0b61a)
• Promoted SearchBarState and slot-based SearchBar APIs to stable. Deprecated older SearchBar APIs using expanded/onExpandedChange. (Ia3793)

Bug Fixes

• Fixed a rendering delay issue where the RichTooltip and PlainTooltip carets would appear late during the entrance animation. (I874b6, b/395753083)
• Update margin values for Input/Scroll variant of TimePicker. (I83f00)
• SplitButton measure trailing button first to guarantee space. (Id3a1e)
• Fixed an accessibility issue where Switch Access users could not activate editable text fields inside ExposedDropdownMenuBox. (I0ea17)
• Fixed talkback announcement order in TextField and OutlinedTextField when a prefix or suffix is present. (Ie79e7)
• Update TimePicker margins and colon placement (I6bfeb)
• Fix focus order in Talkback for ScrollField. (I4ca9f, b/526870141)
• Updated Compose dependencies in Material 3 to 1.12.0-beta01. (Ie9417)
• Tooltips are now clamped to the window boundaries to prevent them from being cut off on small screens or under large font configurations. (I421ff)
• Update ScrollField with more expressive number transitions and adjust sizing/typography (Ic1614)

remote compose: v1.0.0-alpha15

appfunctions: v1.0.0-alpha10

July 01, 2026

androidx.appfunctions:appfunctions:1.0.0-alpha10, androidx.appfunctions:appfunctions-compiler:1.0.0-alpha10, and androidx.appfunctions:appfunctions-testing:1.0.0-alpha10 are released. Version 1.0.0-alpha10 contains these commits.

API Changes

• Added AppFunctionServiceEntryPoint. All AppFunction annotation must be declared within the AppFunctionService that is annotated with AppFunctionServiceEntryPoint (Idc5d5, b/463909015)
• Moved AppFunction and AppFunctionConfiguration APIs . AppFunctionConfiguration will be removed in future release as it will be replaced by AppFunctionServiceEntryPoint (Iaff23, I4cf3e, b/517876475)
• Updated AppFunctionService API to support callback (I6e0d7, b/519880977)
• Add searchAppFunctions API (I8c0f9, I1fa27, b/494239238)

Benchmark: v1.5.0-alpha07

July 01, 2026

androidx.benchmark:benchmark-*:1.5.0-alpha07 is released. Version 1.5.0-alpha07 contains these commits.

API Changes

• Simplified Perfetto trace capture on device. (I48810)
• Move the experimental TraceProcessor.runServer extension APIs from androidx.benchmark:benchmark-macro to androidx.benchmark:benchmark-common, and to the androidx.benchmark package. This will enable their use in microbenchmarks in the future. (Ie25bb, b/393640753)

Bug Fixes

• Update traceprocessor implementation (as well as unbundled Perfetto Trace capture) to use Perfetto v56.0 (I8fb9d)
• Set androidx.benchmark.requireAot and androidx.benchmark.requireAot to true by default. These safer defaults ensure that compilation is performed ahead of running microbenchmarks (on by default with the benchmark gradle plugin when using AGP 8.4+), and that measureRepeated is not used on the main thread, where it can cause ANRs. (I1bc3c, b/379115078)
• Increased perfetto kill timeout from 5 to 30 seconds (for benchmark captured Perfetto sessions only). Added clearer error logging when the issue occurs. (If188f, b/435589290)

• CameraXViewfinder now supports built-in gestures for pinch-to-zoom and tap-to-focus, and adds support for screen flash and stream state. FocusState is now public in viewfinder-core to allow monitoring tap-to-focus results. (I66a17, b/522549890)
• Added isAutoRotationEnabled to SessionConfig.Builder , HighSpeedVideoSessionConfig.Builder, ExtensionSessionConfig.Builder and introduced a Kotlin DSL factory functions for them. This allows setting the appropriate rotation automatically based on device sensors. (I5b4a3, b/510752515)
• Added TransformationMode property to TransformationInfo to support apps to use OpenGL pipeline in EMBEDDED mode. (Id1de1, b/487826941)
• Added isNightModeIndicatorSupported() and getNightModeIndicator() to CameraInfo to determine when the environment conditions meet the criteria for Night Mode. (Iae47b, b/499389465)
• Exposed ImageAnalysis.OUTPUT_IMAGE_FORMAT_PRIVATE and ImageProxy.getHardwareBuffer() as public API to support GPU based ImageAnalysis. (I41cb3, b/496022391, b/492934501)
• ExtensionsManager#getExtensionEnabledCameraSelector is now deprecated. Please use the new ExtensionSessionConfig API for enabling extension modes. (I2b336, b/473715607)
• Added support for visual styling of camera frames during concurrent camera composition. You can now customize:
• Rounded Corners: Use setRoundedCornerRatio(float) to apply normalized rounding (0.0 to 1.0) to frame edges.
• Borders: Use setBorderWidthRatio(float) and setBorderColor(int) to add a decorative frame with consistent thickness (I18a07

Media3: 1.11.0-alpha01

• Common library:
  • Add Format.channelMask to explicitly represent the audio channel mask, and a new Util.getAudioTrackChannelConfig(Format) overload to safely resolve it.
  • Upgrade Kotlin from 2.0.20 to 2.2.0.
• ExoPlayer:
  • Fix a timing-dependent concurrency bug that could cause an IllegalStateException or IndexOutOfBoundsException in ExoPlayer.
  • Relax ad group count checks in AdsMediaSource to allow the ad group count to decrease when an ad group is fully processed (hasUnplayedAds() is false), accommodating dynamic ad group resizing during reset workflows.
  • Add support for ads in multi-period content (e.g., DASH) by splitting and offsetting the AdPlaybackState for each period.
  • Add getFlags() and FLAG_STRICT_DURATION to SampleStream to allow streams to report flags, and update renderers to check these flags dynamically.
  • Fall back to the frame rate estimator in MediaCodecVideoRenderer and to the codec output format in MediaCodecAudioRenderer to calculate the codec operating rate when the stream formats do not provide a valid value, and avoid unnecessary codec resets.
  • Remove clipping of content for client-side inserted ads in the core player. Instead, AdsMediaSource takes care of the clipping logic. Custom client-side inserted ads sources need to be updated to implement the content clipping internally.
  • Mark tracks with a well-formed but unrecognized codec profile or level as supported=NO_EXCEEDS_CAPABILITIES instead of supported=YES (which is how tracks with missing or malformed profile or level info are marked). This ensures these tracks (which are unlikely to be supported by the device) are not selected when there are better-supported alternatives.
  • Add DefaultPreloadManager.SimpleRankingDataComparator, which is a RankingDataComparator that compares the ranks of the media items based on their distances to the index of the current playing media item. Apps can override its compare(Integer, Integer) method if a more fine-tuned comparison logic is needed. The custom SimpleRankingDataComparator can be injected via a new constructor of DefaultPreloadManager.Builder.
  • Reduce the OOM risk of DefaultLoadControl.prioritizeTimeOverSizeThresholds by falling back to buffer byte size limits if available heap memory seems tight.
  • Align handling of still images when MediaItem.imageDurationUs is not set: JPEG and HEIC still images now 'play' with a very short default duration (the same way PNG and other images previously behaved).
  • Add MediaSource.prepareSource(MediaSourceCaller, PlayerId, BandwidthMeter) to plumb BandwidthMeter to MediaSource. The deprecated method with custom implementation will still be called by default though, it is recommended to implement the new method and use BandwidthMeter.getTransferListener() to get parity to the old method.
  • In DefaultBandwidthMeter, add support for a custom InitialBitrateSupplier. This allows apps to provide their own logic for determining the initial bitrate estimate, which will be used on creation of DefaultBandwidthMeter and on network type changes. The supplier can be set via DefaultBandwidthMeter.Builder.setInitialBitrateSupplier().
  • Enable dynamic scheduling by default. ExoPlayer playback work loop will run dynamically as opposed to on a static interval.
  • Remove an unnecessary reset that can occur when joining tracks with pre-roll samples to active playback.
  • In DefaultBandwidthMeter, optimize getInitialBitrateCountryGroupAssignment to return the country group assignments packed into a 32-bit integer instead of an array, reducing code size and avoiding allocations.
  • Fix AudioTrack initialization failures on some devices by ensuring the retry logic always attempts a minimum of 1 second buffer size if other retries (by halving the buffer size) are unsuccessful (#3207).
  • Fix codec issue on some devices where the codec was swallowing all samples if previously flushed before receiving input buffers.
  • Add experimental ExoPlayer.Builder.enablePerStreamMediaProgression() to allow advancing media processing on a per-stream basis. This reduces startup latency between playlist items and avoids playback becoming "stuck" with very short content (#3122).
  • Fix race condition related to audio session id usage where the initial audio session id auto-generated by ExoPlayer would be used instead of the value set by setAudioSessionId (#3241).
  • Add experimental HAGC (ST 2094-50) timed metadata playback support for progressive media (e.g. MP4, Matroska). The player automatically merges HAGC metadata tracks with the associated video track and delivers the metadata out-of-band to the decoder on API 37+ devices. This behavior can be disabled via DefaultMediaSourceFactory.setExperimentalEnableHagcPlayback(false).
• CompositionPlayer:
  • Fix an issue where TrackSelector instances were not being released.
• Transformer:
  • Fix an issue where ExportResult.fileSizeBytes may be over-reported.
• Track selection:
  • Expose BaseTrackSelection.DEFAULT_FORMAT_COMPARATOR and add AdaptiveTrackSelection.Factory.setTrackFormatComparator to allow custom format ordering and ABR selection priority beyond bitrate-only ordering.
• Extractors:
  • MP4, MP3, and FLAC: Add FLAG_DISABLE_ARTWORK_METADATA to allow discarding attached pictures and cover art metadata during container parsing to reduce runtime memory consumption (#2077). This can also be enabled centrally via DefaultExtractorsFactory.setDisableArtworkMetadata.
  • MP4: Add support for extracting ITU-T T.35 (it35) timed metadata tracks.
  • MP4: Add support for extracting chapter metadata (both Nero and QuickTime formats). QuickTime chapters are preferred if both are present. The extracted chapter information is exposed as Chapter entries within the track's Metadata, allowing for native chapter navigation in MP4, M4A, and M4B files (such as audiobooks and podcasts) (#2803).
  • WAV, Matroska, and MP4: Add support for 64-bit floating point PCM audio (#3090).
  • Matroska: Use codec bitstream metadata to populate accurate ColorInfo.
  • MP4: Add support for seeking in fragmented MP4 files using the mfra box when a sidx box is not present. To enable this, provide FLAG_READ_MFRA_FOR_SEEK_MAP to the FragmentedMp4Extractor, which is now done by default in DefaultExtractorsFactory (#3088).
  • Ignore av1C data with unsupported version.
  • MP4: Add support for big-endian floating point PCM in fpcm boxes.
  • Matroska: Parse chapter info to Chapter entries in a track's Metadata.
  • MPEG-TS: Improve extraction of DTS-HD and DTS Express streams by combining the Core and Extension Substream into a single sample, fixing playback issues where the two were previously output as separate samples (#3147).
  • MP4: Prevent infinite loops and out-of-bounds reads when parsing emp...
