How to inject Repository in ordinary classes using hilt-CodePudding

MyRepository

class MyRepository @Inject constructor(
    private val myDao: IMyDao
){    
   ...
}

MyModule

@InstallIn(SingletonComponent::class)
@Module
class MyModule {   

    @Provides
    fun provideMyRepository(MyDao: IMyDao): MyRepository{
        return MyRepository(MyDao)
    }

}

Use in Worker

class MyWorker(appContext: Context, workerParams: WorkerParameters) :
    Worker(appContext, workerParams) {

    private val myRepository: MyRepository =
        EntryPointAccessors.fromApplication(appContext, MyRepository::class.java)
}

start worker in Application class.

but got error: java.lang.ClassCastException: Cannot cast com.freedom.android.DaggerMyApplication_HiltComponents_SingletonC$SingletonCImpl to com.freedom.android.MyRepository

I read the relevant documentation.But I don't want to use the interface, I just want the class to be provided.

Please tell me what is the problem.

CodePudding user response：

In this case you need to use hilt worker

  @HiltWorker class WokerName @AssistedInject constructor(
       @Assisted appContext: Context,
       @Assisted params: WorkerParameters,
       myRepository: MyRepository): CoroutineWorker(appContext, params)
