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

  • •GlobalScope: **No GlobalScope**: Use structured scopes.
  • •Async/Await: **Avoid Async**: Prefer simple suspend functions unless parallel execution is needed.
