Testing rebooted (with AndroidX Test)
summary
AndroidX Test 1.0 ships with concrete, cross‑runtime APIs: ApplicationProvider for a single app context, ActivityScenario with moveToState and recreate to drive lifecycle testing, FragmentScenario, Espresso and Truth Android subjects for intent and view assertions. Roboelectric 4.0 and device runs use the same tests; verification runs across API level 15 through latest. Recommended flow: iterate locally with Robolectric, then run identical tests on virtual/real devices before submit.
