# Android Background Work Standards

## **Priority: P1 (HIGH)**

## Implementation Guidelines

### WorkManager

- **CoroutineWorker**: Use for all background tasks.
- **Constraints**: explicit (Require Network, Charging).
- **Hilt**: Use `@HiltWorker` for DI integration. Inject dependencies via `@AssistedInject` constructor; bind with `HiltWorkerFactory` in `WorkManager` configuration.

### Foreground Services

- **Only When Necessary**: Use generating visible notifications only for tasks user actively aware of (Playback, Calls, Active Navigation). Otherwise use WorkManager.

## Anti-Patterns

- **No IntentService**: Deprecated. Use WorkManager for all background tasks.
- **No Short Background Jobs**: Use Coroutines in ViewModel scope instead.
