Benchmark: v1.2.0

October 18, 2023

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

Important changes since 1.1.0

Baseline Profiles

• New Baseline Profile Gradle Plugin automates capturing and including baseline profiles in your test and build workflow.
• BaselineProfileRule.collect now stable, a streamlined and simplified version of the previous experimental BaselineProfileRule.collectBaselineProfile API
  • Just specify packageName, and drive your app
• For libraries generating baseline profiles, you can now filter the rules generated either in code (BaselineProfileRule.collect argument), or even more simply in the gradle plugin
• Fixes
  • Fixed baseline profile collection on Android U+ (Id1392, b/277645214)

Macrobenchmark

• Compilation
  • Macrobenchmark now correctly fully resets compilation state for each compile - this requires reinstalling the APK prior to Android 14, so benchmarking on Android 14+ is strongly recommended if you want to persist state (like user login) in what's being measured.
  • You can also work around this by controlling app compilation separately, and skipping compilation with CompilationMode.Ignore() or instrumentation argument

• Instrumentation Arguments

  • Support for androidx.benchmark.dryRunMode.enable instrumentation argument, (already available in microbenchmark) for quicker validation runs (e.g. when creating the benchmark, or in presubmit)
  • Support for androidx.benchmark.profiling.mode=StackSampling and MethodTracing.
  • Added androidx.benchmark.enabledRules to allow runtime filtering baseline profile vs macrobenchmark rule tests
  • Added androidx.benchmark.perfettoSdkTracing.enable argument to enable tracing with tracing-perfetto, e.g. Compose recomposition tracing. Note that when used with StartupMode.COLD, timing will be significantly affected as the tracing library is loaded and enabled during app startup.

• Requirements

  • Macrobenchmark now requires ProfileInstaller 1.3.0 or greater in the target app, to enable profile capture / reset, and shader cache clearing.

• New Experimental Metric APIs

  • Added experimental TraceSectionMetric, which allows for extracting simple timing from trace("") {} blocks in your app, or TraceMetric for leveraging the full query capability of Perfetto TraceProcessor.
  • Added experimental PowerMetric to capture power usage information
  • Added experimental MemoryCountersMetric to count page faults
  • Added experimental PerfettoTraceProcessor API, which is used internally to extract metrics from System traces (aka Perfetto traces)

• Fixes

  • Fixed crashes when installing or extracting profiles from an app installed from multiple APKs (e.g. from app bundle).
  • Fixed FrameTimingMetric ignoring frames with inconsistent frame IDs (generally, frames during ripples on API 31+) (I747d2, b/279088460)
  • Fixed parsing errors on traces > 64MB (Ief831, b/269949822)
  • Clarified errors when device (especially emulator) OS image not correctly configured for tracing, or compilation
  • Skip battery level check for devices without battery (micro and macro)
  • Improved file output, with more clear errors for invalid output directories, and safer defaults
  • Improved stability of StartupMode.COLD by consistently dropping the shader cache (also exposed via MacrobenchmarkScope.dropShaderCache)
  • Fixed leanback fallback for startActivityAndWait.

Microbenchmark

• Features
  • Profiling was moved to a separate phase, after other metrics, so one test run can display both accurate timing and profiling results.
• Experimental APIs
  • Added experimental MicrobenchmarkConfig API for defining custom metrics and configuring tracing and profiling. Can be used to capture method traces, or capture tracepoints (but be aware of tracing overhead).
  • Added experimental APIs for controlling BenchmarkState separately from BenchmarkRule, without JUnit
  • Added experimental PerfettoTrace record to enable capturing Perfetto traces, with custom configuration, separate from benchmark APIs.
• Fixes
  • Workaround missing leading whitespaces in Android Studio benchmark output.
  • Fix issue where warnings could fail to print in Android Studio benchmark output.
  • Fixed SampledProfiling crash on Android 13 (API 33) and higher.
  • Massively improved performance of dryRunMode by skipping IsolationActivity and Perfetto tracing (Up to 10x faster dry run mode on older OS versions).

Important changes since 1.7.0

• Predictive Back - The OnBackPressedCallback now offers new Predictive Back callbacks for handling the back gesture starting, progress throughout the gesture, and the back gesture being canceled in addition to the previous handleOnBackPressed() callback for when the back gesture is committed. This also comes with the PredictiveBackHandler Composable to handle predictive back gesture events in Activity Compose. It provides a Flow of BackEventCompat objects that must be collected in the suspending lamba you provide:

  PredictiveBackHandler { progress: Flow<BackEventCompat> ->
    // code for gesture back started
    try {
      progress.collect { backEvent ->
      // code for progress
    }
    // code for completion
    } catch (e: CancellationException) {
      // code for cancellation
    }
  }

ComponentActivity.onBackPressed() has now been deprecated in favor of the APIs for handling back. Developers should now utilize the OnBackPressedDispatcher, rather than overriding this method.

• EdgeToEdge - ComponentActivity.setUpEdgeToEdge() has been added to easily set up the edge-to-edge display in a backward-compatible manner.

Collection: v1.4.0-alpha01

October 4, 2023

androidx.collection:collection-*:1.4.0-alpha01 is released. Version 1.4.0-alpha01 contains these commits.

New Features

New high-efficiency collections have been added that have low allocation overhead and high performance: - MutableScatterMap & ScatterMap - Classes with MutableMap & Map-like API - MutableScatterSet & ScatterSet - Classes with MutableSet & Set-like API - MutableObjectList & ObjectList - Classes with MutableList & List-like API

New high-efficiency collections for storing primitives without boxing have been added: - Mutable[Int|Float|Long]List - Classes with MutableList<Int|Float|Long>-like API. The read-only [Int|Float|Long]List also exists. For example, integers can be held in an IntList. - Mutable[Int|Float|Long]Set - Classes with MutableSet<Int|Float|Long>-like API. The read-only [Int|Float|Long]Set also exists. For example, integers can be held in an IntSet. - Mutable[Int|Float|Long|Object][Int|Float|Long|Object]Map - Classes with Mutable<Int|Float|Long,T, Int|Float|Long|T>-like API. The read-only [Int|Float|Long|Object][Int|Float|Long|Object]Map also exists. For example, a map with an integer key and a reference type value is an IntObjectMap<T>.

Media3: v1.2.0-alpha02

• Common Library:
  • Upgrade androidx.annotation:annotation-experimental to 1.3.1. This also introduces a transitive dependency on the Kotlin standard library from media3-common. Apps can downgrade to remove this dependency if they want. Fixes https://issuetracker.google.com/251172715.
  • Move ExoPlayer.setAudioAttributes to the Player interface.
• ExoPlayer:
  • Add additional fields to Common Media Client Data (CMCD) logging: next object request (nor) and next range request (nrr) (#8699).
  • Add functionality to transmit Common Media Client Data (CMCD) data using query parameters (#553).
  • Fix ConcurrentModificationException in ExperimentalBandwidthMeter (#612).
  • Add MediaPeriodId parameter to CompositeMediaSource.getMediaTimeForChildMediaTime.
  • Support ClippingMediaSource (and other sources with period/window time offsets) in ConcatenatingMediaSource2 (#11226).
  • Change BaseRenderer.onStreamChanged() to also receive a MediaPeriodId argument.
• Transformer:
  • Changed frameRate and durationUs parameters of SampleConsumer.queueInputBitmap to TimestampIterator.
• Extractors:
  • Add BmpExtractor.
  • Add WebpExtractor.
  • Add HeifExtractor.
  • Add QuickTime classic support to Mp4Extractor.
• Audio:
  • Add support for Opus gapless metadata during offload playback.
  • Allow renderer recovery by disabling offload if failed at first write (#627).
  • Enable Offload Scheduling by default for audio-only offloaded playback.
  • Delete ExoPlayer.experimentalSetOffloadSchedulingEnabled and AudioOffloadListener.onExperimentalOffloadSchedulingEnabledChanged.
  • Renamed onExperimentalSleepingForOffloadChanged as onSleepingForOffloadChanged and onExperimentalOffloadedPlayback as onOffloadedPlayback.
• Effect:
  • Changed frameRate and durationUs parameters of VideoFrameProcessor.queueInputBitmap to TimestampIterator.
• IMA extension:
  • Fix bug where a multi-period DASH live stream that is not the first item in a playlist can throw an exception (#571).
  • Release StreamManager before calling AdsLoader.destroy()
  • Bump IMA SDK version to 3.31.0.
• Session:
  • Set the notifications foreground service behavior to FOREGROUND_SERVICE_IMMEDIATE in DefaultMediaNotificationProvider (#167).
  • Use only android.media.session.MediaSession.setMediaButtonBroadcastReceiver() above API 31 to avoid problems with deprecated API on Samsung devices (#167).
  • Use the media notification controller as proxy to set available commands and custom layout used to populate the notification and the platform session.
  • Convert media button events that are received by MediaSessionService.onStartCommand() within Media3 instead of routing them to the platform session and back to Media3. With this, the caller controller is always the media notification controller and apps can easily recognize calls coming from the notification in the same way on all supported API levels.
  • Fix bug where MediaController.getCurrentPosition() is not advancing when connected to a legacy MediaSessionCompat.
  • Add MediaLibrarySession.getSubscribedControllers(mediaId) for convenience.
  • Override MediaLibrarySession.Callback.onSubscribe() to assert the availability of the parentId for which the controller subscribes. If successful, the subscription is accepted and notifyChildrenChanged() is called immediately to inform the browser (#561).
• RTSP Extension:
  • Fix a race condition that could lead to IndexOutOfBoundsException when falling back to TCP, or playback hanging in some situations.
  • Check state in RTSP setup when returning loading state of RtspMediaPeriod (#577).
  • Ignore custom RTSP request methods in Options response public header (#613).
• Leanback extension:
  • Fix bug where disabling a surface can cause an ArithmeticException in Leanback code (#617).
