Agent-skills-standard 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)

Android Concurrency Standards

Priority: P0

Implementation Guidelines

Structured Concurrency

  • Scopes: Always use 
    viewModelScope
    (VM) or 
    lifecycleScope
    (Activity/Fragment).
  • Dispatchers: INJECT Dispatchers (
    DispatcherProvider
    ) for testability. 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.
