| /** | ||
| * This test class generates a basic startup baseline profile for the target package. | ||
| * | ||
| * We recommend you start with this but add important user flows to the profile to improve their performance. | ||
| * Refer to the [baseline profile documentation](https://d.android.com/topic/performance/baselineprofiles) | ||
| * for more information. | ||
| * | ||
| * You can run the generator with the "Generate Baseline Profile" run configuration in Android Studio or | ||
| * the equivalent `generateBaselineProfile` gradle task: | ||
| * ``` | ||
| * ./gradlew :app:generateReleaseBaselineProfile | ||
| * ``` | ||
| * The run configuration runs the Gradle task and applies filtering to run only the generators. | ||
| * | ||
| * Check [documentation](https://d.android.com/topic/performance/benchmarking/macrobenchmark-instrumentation-args) | ||
| * for more information about available instrumentation arguments. | ||
| * | ||
| * After you run the generator, you can verify the improvements running the [StartupBenchmarks] benchmark. | ||
| * | ||
| * When using this class to generate a baseline profile, only API 33+ or rooted API 28+ are supported. | ||
| * | ||
| * The minimum required version of androidx.benchmark to generate a baseline profile is 1.2.0. | ||
