To run the generator:
./gradlew :benchmark:connectedReleaseAndroidTest -P android.testInstrumentationRunnerArguments.androidx.benchmark.enabledRules=BaselineProfileThe output can be found in: [module]/build/outputs/connected_android_test_additional_output/release/connected/[device].
Copy and rename the file to baseline-prof.txt and place it in the src/main directory of your app module.
./gradlew :benchmark:connectedReleaseAndroidTest -P android.testInstrumentationRunnerArguments.androidx.benchmark.enabledRules=MacrobenchmarkDatabase interactions and push notifications are implemented using Firebase Cloud Functions.
The backend repository is also open-sourced: budgetplus-cloud-functions
