Benchmark: v1.3.1

September 18, 2024

androidx.benchmark:benchmark-*:1.3.1 is released. Version 1.3.1 contains these commits.

Bug Fixes

• Added gradle property androidx.baselineprofile.suppressWarnings to suppress all baseline profile warnings (I7c36e, b/349646646)
• Fixed Baseline Profile Gradle Plugin to use pre-existing nonMinified… and benchmark… if created by the app instead of creating wrappers. (Ia8934, b/361370179)
• Fixed java.lang.AssertionError: ERRORS (not suppressed): EMULATOR when automaticGenerationDuringBuild is enabled on emulators. New argument is used to instead skip the test. (If3f51, b/355515798)
• Microbenchmark minification - keep subclasses of org.junit.runner.notification.RunListener in benchmark library proguard (Ic8ed5, b/354264743)
• Fix TraceSectionMetric to Ignore non-terminating slices. Previously these were considered to have -1 duration, e.g. during summation or finding minimum duration. (If74b7)
• Fixed an issue in FrameTimingGfxInfoMetric where starting the metric would crash if the process wasn't already running. (I6e412)

Benchmark: v1.4.0-alpha01

September 18, 2024

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

New Feature - App Startup Insights

• Initial version of app startup insights can be enabled in Macrobenchmark. (09fae38)

To enable in a startup benchmark:

  @Test
  fun startup {
      macrobenchmarkRule.measureRepeated(
          …
          packageName = "com.example.my.application.id"
          metrics = listOf(StartupTimingMetric()),
          iterations = 5,
          startupMode = StartupMode.COLD,
          compilationMode = CompilationMode.None(),
          ExperimentalConfig(StartupInsightsConfig(isEnabled = true))
          ) {
          scope.startActivityAndWait(...)
      }
  }

Then running your startup benchmark will analyze the trace to look for common problems, and print them after metrics to Studio test output in the benchmark tab, e.g.:

StartupBenchmark_startup[startup=COLD,compilationMode=None]
├── Metrics
│   ├──   timeToFullDisplayMs                min  1,147.2,   median  1,208.8,   max  1,307.4
│   └──   timeToInitialDisplayMs             min  1,147.2,   median  1,208.8,   max  1,307.4
├── App Startup Insights
│   ├── App in debuggable mode (expected: false)
│   │   └── seen in iterations: 0(true) 1(true) 2(true) 3(true) 4(true) 5(true) 6(true) 7(true) 8(true) 9(true)
│   ├── Potential CPU contention with another process (expected: < 100000000ns)
│   │   └── seen in iterations: 4(105022546ns)
│   └── Main Thread - Binder transactions blocked (expected: false)
│       └── seen in iterations: 7(true)
└── Traces
    └── Iteration 0 1 2 3 4 5 6 7 8 9

This feature is still a work-in-progress, with improvements to documentation and extensibility to follow, but feedback is welcome.

New Features

• Added gradle property androidx.baselineprofile.suppressWarnings to suppress all baseline profile warnings. (314153a)
• Microbench metrics are now displayed in Perfetto traces as counters. (3214854)
• Add experimental scripts for disabling jit (requires root / runtime restart), and resetting device perf/test state. These are not currently published as gradle tasks. (7c3732b)
• Added benchmark argument to skip tests when running on emulator. When automaticGenerationDuring build is enabled, benchmarks will also trigger baseline profile generation. This will fail, if emulators are used. With the new argument skipBenchmarksOnEmulator we can instead skip the test. (0c2ddcd)
• Change perf event enable logic to run on API 23+ (2550048)

API Changes

• Existing experimental PerfettoConfig argument to MacrobenchmarkRule.measureRepeated() moved to the new ExperimentalConfig object.

Bug Fixes

• Increase lockClocks.sh retry count (99e9dac)
• Don't create nonMinified and benchmark build types if existing. Due to a bug, even if nonMinified and benchmark build types existed, they were going to be recreated. (e75f0a5)
• Ignore non-terminating slices from TraceSectionMetric results. (a927d20)
• Improved emulator check to consider sdk_ prefix. (1587de8)
• Treat non-running packages as cleared in FrameTimingGfxInfoMetric. (35cc79c)
• Fix androidx.benchmark.cpuEventCounter producing corrupt values for non-Instruction events. (06edd59)
• Fix resumeTiming/runWithTimingDisabled to respect metric priority order, and significantly reduce impact of lower priority metric pause/resume on higher priority metric results. For example, if using cpu perf counters via cpuEventCounter.enable instrumentation argument, timeNs is no longer significantly reduced when pause/resume occur. (5de0968)

New Features

• Added a new lint rule to ensure the use of the popBackStack function that takes a reified class type when attempting to popBackStack using type-safe APIs. (Ief161, b/358095343)

Bug Fixes

• Navigation now requires that the route passed to a NavGraph's startDestination contains the values for all required arguments, which includes arguments that are non-nullable and have no default value. (I18e74, b/362594265)
• Navigation safe args has added support for non-nullable strings such that "null" values will be parsed and stored into the bundle as is. This departs from existing behavior where "null" values are parsed into a null object. This change only applies to non-nullable String types. Nullable strings remain unchanged. (I08b4a, b/348936238)
• A NavDestination can no longer be deeplinked into except through a deep link that was explicitly added to the destination. This also means that you can only navigate to a destination's route with the navigate function overload that takes a string route. This fixes a vulnerability that made it possible to deep link to a potentially protected destination. (Ie30e6)

Dependency Update

• Navigation Safe Args now depends on Kotlin 1.9.24, rather than Kotlin 2.X, ensuring that developers are not forced to update. (a4129a)
• Navigation Compose now depends on Compose 1.7.2.

• We have removed support for using EdgeButton with Column, due to the need to specify the EdgeButton height explicitly in ScreenScaffold. (Ie353d)
• We have added support for the Wear Compose LazyColumn with our ScreenScaffold (and added an implementation of ScrollInfoProvider for LazyColumnState). (Ib8d29)
• We have combined LocalTextMaxLines, LocalTextAlign, LocalTextOverflow into a single LocalTextConfiguration composition local to provide a more scalable solution going forwards. (I5edbc)
• We have added arc-large as an additional typescale, reserved for short header text strings at the very top or bottom of the screen, like in Confirmation overlays. (I60e3e)
• We have added defaults to Button for recommended large and extra large icon sizes and content padding. (I84675)

Bug Fixes

• We have updated the colors for IconButton and TextButton. (I48324)
