 We can significantly reduce emulator startup time by setting up AVD snapshot caching:
 
-1. add an `actions/cache@v2` step for caching the `avd`
-2. add a `reactivecircus/android-emulator-runner@v2` step to generate a clean snapshot - specify `emulator-options` without `no-snapshot`
-3. add another `reactivecircus/android-emulator-runner@v2` step to run your tests using existing AVD / snapshot - specify `emulator-options` with `no-snapshot-save`
+1. add a `gradle/gradle-build-action@v2` step for caching the Gradle, more details see [#229](https://github.com/ReactiveCircus/android-emulator-runner/issues/229)
