Macrobenchmark Sample

This sample project shows how to use the Jetpack Macrobenchmark library.

See the Macrobenchmark guide for more information on the library.

Samples

The sample project includes the following:

  • SampleStartupBenchmark measures the application startup time for a trivial Activity with a single TextView.

  • SmallListStartupBenchmark measures the application startup time for an Activity with a RecyclerView and an Activity with a Compose LazyColumn.

  • FrameTimingBenchmark scrolls a simple RecyclerView and Compose LazyColumn, measuring frame timing / jank.

Running

Open the MacrobenchmarkSample project in Android Studio Bumblebee or later, and run benchmarks as you usually would run tests: Ctrl-Shift-F10 (Mac: Ctrl-Shift-R)

Alternatively, run the benchmarks from terminal with:

./gradlew macrobenchmark:cC
