To use the this sample, you will need to run the following command to download the google/benchmark dependency:
git pull --recurse-submodules
You will also need the NDK, and CMake dependencies installed. You can do this
from Android Studio Settings, go to Appearance & Behavior > System Settings
Android SDK,SDK Toolstab.
This sample project shows how to use the Jetpack Benchmark library together with the NDK.
It layers most of the features of the Jetpack Benchmark library on top of https://github.com/google/benchmark, including:
- Clock locking (script, Sustained Performance mode, or throttle detection)
- Activity launch to run Benchmark in foreground
- Joined benchmark data reporting through JSON/XML
- Running and reporting through Android Studio
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.
