hilt-providers

Create an @Module object installed in SingletonComponent with a @Provides @Singleton method that builds the database via Room.databaseBuilder using @ApplicationContext. Add separate @Provides methods for each DAO that receive the database as a parameter.

Use @Binds in an abstract class to map an interface to its implementation when the implementation has an @Inject constructor. Use @Provides only when you cannot annotate the constructor, such as for third-party classes or builder-based configuration.

Annotate the Worker with @HiltWorker and use @AssistedInject with @Assisted Context and WorkerParameters. Then configure HiltWorkerFactory in your Application class by implementing Configuration.Provider and setting the factory in the WorkManager configuration.

MissingBinding occurs when no @Provides or @Binds method exists for the requested type in the correct component scope. Fix it by adding the binding to the appropriate module, or add an @Inject constructor to the class being requested.

No, injecting Context without a qualifier fails. Use @ApplicationContext for application-scoped needs like databases and DataStore, or @ActivityContext for activity-scoped dependencies, and never inject Application or Activity directly.
