android-concurrency
Standards for Coroutines, Flow, and Threading. Use when writing suspend functions, choosing coroutine scopes, switching between StateFlow and SharedFlow, injecting Dispatchers for testability, or debugging threading issues in Android. (triggers: **/*ViewModel.kt, **/*UseCase.kt, **/*Repository.kt, suspend, viewModelScope, lifecycleScope, Flow, coroutine, Dispatcher, DispatcherProvider, GlobalScope)
Best use case
android-concurrency is best used when you need a repeatable AI agent workflow instead of a one-off prompt.

Teams using android-concurrency should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# Android Concurrency Standards ## **Priority: P0** ## Implementation Guidelines ### Structured Concurrency - **Scopes**: Always use `viewModelScope` (VM) or `lifecycleScope` (Activity/Fragment). - **Dispatchers**: INJECT Dispatchers (`DispatcherProvider`) for testability. Do not hardcode `Dispatchers.IO`. ### Flow usage - **Cold Streams**: Use `Flow` for data streams. - **Hot Streams**: Use `StateFlow` (State) or `SharedFlow` (Events). - **Collection**: Use `collectAsStateWithLifecycle()` (Compose) or `repeatOnLifecycle` (Views). ## Anti-Patterns - **No GlobalScope**: Use viewModelScope or lifecycleScope — never GlobalScope. - **No async/await by default**: Prefer simple suspend functions; async only for parallel calls. ## References - [Dispatcher Pattern](references/implementation.md)
