BaselineProfileApplication

Application to test baselineprofile library under a clean library install

Guide

Run the following command to generate the baseline-prof.txt file.

./gradlew :app:generateReleaseBaselineProfile -Pandroid.testInstrumentationRunnerArguments.androidx.benchmark.enabledRules=BaselineProfile

The generated file will be found under build package of baselineprofile module. Go to outputs then to connected_android_test_additional_output folder and look for the device used on tests. It's the one ending with prof.txt. Put this file inside main app package with Android Manifest and rename it to baseline-prof.txt.

Run the following command to collect application startup and journeys metrics.

./gradlew :baselineprofile:connectedAndroidTest -Pandroid.testInstrumentationRunnerArguments.androidx.benchmark.enabledRules=Macrobenchmark

Discoveries

• We don't need macrobenchmark library import, just baselineprofile and profileinstaller.
• BaselineProfile needs his own module, like macrobenchmark.
• Using alpha versions of baselineprofile library allows run baseline generating tasks without rooted physical devices.
• Maybe it's necessary upgrade gradle to 8.0.0 or above versions.
• BaselineProfile library already contains macrobenchmark jetpack library. The opposite is not true.
