Use this skill to launch, drive, and tear down an Activity from an instrumentation test using ActivityScenario and the JUnit4 wrapper ActivityScenarioRule. Covers ActivityScenario.launch (), launch(intent), launchActivityForResult, moveToState(Lifecycle.State.), recreate(), onActivity { }, the Closeable / use { } idiom, and the manifest declaration trap. Establishes that androidx.test.ext.junit.rules.ActivityScenarioRule is the single canonical FQN — androidx.test.rule.ActivityScenarioRule does NOT exist; the package only ships the deprecated ActivityTestRule. Use when the user reports ActivityNotFoundException, ActivityTestRule deprecated, "how do I rotate the activity in a test", "how do I read setResult from a test", "how do I survive recreate", "Cannot run onActivity since Activity is not alive", or "test deadlocks on launch".

Review the setup. Your agent checks the skill’s instructions, requirements, and installation scope.
Use this skill to launch, drive, and tear down an Activity from an instrumentation test using `ActivityScenario` and the JUnit4 wrapper `ActivityScenarioRule`. Covers `ActivityScenario.launch<A>()`, `launch(intent)`, `launchActivityForResult`, `moveToState(Lifecycle.State.*)`, `recreate()`, `onActivity { }`, the `Closeable` / `use { }` idiom, and the manifest declaration trap. Establishes that `androidx.test.ext.junit.rules.ActivityScenarioRule` is the single canonical FQN — `androidx.test.rule.ActivityScenarioRule` does NOT exist; the package only ships the deprecated `ActivityTestRule`. Use when the user reports `ActivityNotFoundException`, `ActivityTestRule deprecated`, "how do I rotate the activity in a test", "how do I read setResult from a test", "how do I survive recreate", "Cannot run onActivity since Activity is not alive", or "test deadlocks on launch".
