Previously with ActivityTestRule, one was able to override beforeActivityLaunched and afterActivityFinished to control app state before and after all tests (e.g, implementing a custom rule Class that extended ActivityTestRule that would be used in all tests). With ActivityScenarioRule marked final and without these protected methods, where/how is this logic now moved to with regard to how one controls before and after an activity? What's the recommended approach now if one were to write a custom rule to be applied to all tests?
