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.
Launching Activities With Activityscenario is a community-contributed Claude Code skill in the tools-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/launching-activities-with-activityscenario/ and loads when your prompt matches the skill's trigger.
When to invoke it: 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".
The Launching Activities With Activityscenario Claude Code skill is built for developers, power users, and teams automating repetitive workflows and improving developer experience. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 116,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
