This sample project shows how to use the Jetpack Benchmark library.
It includes multiple simple benchmark samples:
-
AutoBoxingBenchmark measures the cost of allocating Integer() objects.
-
BitmapBenchmark measures the cost of accessing Bitmap pixels, showing the overhead of many JNI calls versus one in the underlying Android platform code.
As well as one more complex UI benchmark:
- RecyclerViewBenchmark measures the cost of scrolling a RecyclerView UI defined in another UI library module.
Open the project in Android Studio 3.4 or later, and run benchmarks as you usually would run tests: Ctrl-Shift-F10 (Mac: Ctrl-Shift-R)
If you have a rooted device you can benchmark on, use ./gradlew lockClocks to
lock the CPU clocks of the device to stable values. To unlock clocks, use
./gradlew unlockClocks, or reboot your device. This feature is provided by the
androidx.benchmark gradle plugin.
