Launching Activities With Activityscenario

Category: Dev Tools  ·  Sub-category: tools-misc  ·  Last updated:
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".

From the source SKILL.md

ActivityScenario is the modern replacement for the deprecated ActivityTestRule. It provides a thread-safe, lifecycle-aware handle to drive an Activity through CREATED / STARTED / RESUMED / DESTROYED, recreate it for configuration-change emulation, and post work onto its UI thread via onActivity { }. The JUnit4 wrapper ActivityScenarioRule calls launch in before and close in after. This skill encodes the canonical FQN trap, the threading rules, and the manifest requirement.

What this skill does
