Android Coroutines Expert Skill

This skill provides authoritative rules and patterns for writing production-quality Kotlin Coroutines code on Android. It enforces structured concurrency, lifecycle safety, and modern best practices (2025 standards).

Responsibilities

• Asynchronous Logic: Implementing suspend functions, Dispatcher management, and parallel execution.
• Reactive Streams: Implementing Flow, StateFlow, SharedFlow, and callbackFlow.
• Lifecycle Integration: Managing scopes (viewModelScope, lifecycleScope) and safe collection (repeatOnLifecycle).
• Error Handling: Implementing CoroutineExceptionHandler, SupervisorJob, and proper try-catch hierarchies.
• Cancellability: Ensuring long-running operations are cooperative using ensureActive().
• Testing: Setting up TestDispatcher and runTest.
