Android Dependency Injection (Hilt)
SkillAI & modelsConfigure Hilt dependency injection with proper scoping, modules, and constructor injection in Android. Use when changing the production Hilt graph; defer test overrides, Room wiring, navigation-specific scopes, and generic DI explanations to their specific skills.
Available today. Use it from your connected AI after setup.

Priority: P0 (CRITICAL)
1. Bootstrap Hilt
- Annotate
Applicationclass with@HiltAndroidApp. - Annotate Activities/Fragments with
@AndroidEntryPoint.
See module templates for bootstrap and module examples.
2. Define Modules
- Use
@Binds(abstract class) over@Provideswhen possible — generates smaller code. - explicit with
@InstallIn(SingletonComponent,ViewModelComponent).
See module templates for @Binds examples.
3. Prefer Constructor Injection
- Use
@Inject constructor(...)over field injection. - Use
@AssistedInjectfor runtime parameters.
Anti-Patterns
- No Manual Dagger Components: Use Hilt — it generates all wiring.
- No Field Injection in Logic: Use constructor injection; field injection only in Android framework classes.
