Android Performance
A collection of samples using the performance libraries.
JankStats sample
This sample shows how to set up and use the JankStats library to detect janky frames.
Macrobenchmark sample
This sample shows how to use the MacrobenchmarkSample library for testing application startup and runtime performance cases, such as scrolling a RecyclerView or LazyColumn to measure jank.
The sample also includes a GitHub workflow to run Macrobenchmarks on Firebase Test Lab. For more information refer to the README.md.
The Macrobenchmark sample also demonstrates using Jetpack Compose with Macrobenchmark.
Microbenchmark sample
This sample shows how to use the Benchmark library to benchmark code and UI from library modules.
Important Notes
- Make sure your device's screen is on before running benchmarks
- Don't forget to checkout submodules:
git submodule update --init --recursive
