Android Dagger 2.11中的BroadcastReceiver

Question

I m trying to inject broadcast receiver with dagger in android. I m using dagger 2.11. I have BroadcastReceiver module class, component class, and I implement HasBroadcastReceiverInjector in Application class. Do I have to implement HasBroadcastReceiverInjector in Application class, or I can implement HasBroadcastReceiverInjector in Activity class. Has anybody successed to inject BroadcastReceiver with dagger, or someone knows what am I doing wrong

Here is my BroadcastReceiver module class

@Subcomponent(modules = LikeBroadcastReceiverModule.class)
public interface LikeBroadcastReceiverComponent extends AndroidInjector<LikeBroadcaseReceiver> {

@Subcomponent.Builder
abstract class Builder extends AndroidInjector.Builder<LikeBroadcaseReceiver>{}}

Here is my BroadcastReceiver module class

@Module
public class LikeBroadcastReceiverModule {

@Provides
public LikeBroadcastReceiverView provideBroadcastView(LikeBroadcaseReceiver likeBroadcaseReceiver){
    return likeBroadcaseReceiver;
}

@Provides
public BroadcastReceiverPresenter providePresenter(){
    return new BroadcastReceiverPresenterImpl();
}}

Here is my Application class

public class EasyDriveApplication extends Application implements HasActivityInjector, HasBroadcastReceiverInjector{

@Inject
DispatchingAndroidInjector<Activity> activityDispatchingAndroidInjector;

@Inject
DispatchingAndroidInjector<BroadcastReceiver> broadcastReceiverDispatchingAndroidInjector;

@Override
public void onCreate() {
    super.onCreate();
    //Fabric.with(this, new Crashlytics());
    DaggerAppComponent.builder().application(this).build().inject(this);
}

@Override
public AndroidInjector<Activity> activityInjector() {
    return activityDispatchingAndroidInjector;
}

@Override
public AndroidInjector<BroadcastReceiver> broadcastReceiverInjector() {
    return broadcastReceiverDispatchingAndroidInjector;
}}

and here is my AppComponent class

@Singleton
@Component(modules = {
    AndroidInjectionModule.class,
    AppModule.class,
    DaoModule.class,
    MapperModule.class,
    UseCaseModule.class,
    ThreadingModule.class,
    UtilsModule.class,
    BroadcastReceiverBuilder.class,
    ActivityBuilder.class
    })
public interface AppComponent {

@Component.Builder
interface Builder {
    @BindsInstance
    Builder application(Application application);
    AppComponent build();
}

void inject(EasyDriveApplication app);}

and my BroadcastReceiverBuilder class is looks like

@Module
public abstract class BroadcastReceiverBuilder {

@Binds
@IntoMap
@BroadcastReceiverKey(LikeBroadcaseReceiver.class)
abstract AndroidInjector.Factory<? extends BroadcastReceiver> bindLikeBroadcastReceiver(LikeBroadcastReceiverComponent.Builder builder);}

This is error I get

Error:(46, 10) error: com.presentation.dagger.broadcastReceiver.LikeBroadcastReceiverComponent.Builder cannot be provided without an @Provides-annotated method. com.presentation.dagger.broadcastReceiver.LikeBroadcastReceiverComponent.Builder is injected at com.presentation.dagger.application.module.BroadcastReceiverBuilder.bindLikeBroadcastReceiver(builder) java.util.Map,javax.inject.Provider>> is injected at dagger.android.DispatchingAndroidInjector.(injectorFactories) dagger.android.DispatchingAndroidInjector is injected at com.presentation.dagger.application.EasyDriveApplication.broadcastReceiverDispatchingAndroidInjector com.presentation.dagger.application.EasyDriveApplication is injected at com.presentation.dagger.application.AppComponent.inject(app)

I found this page whilst trying to find a way of dependency injecting into a BroadcastReceiver, for anyone else who hits on an issue here is how to do it

@Provides
fun providesBlah() : Blah = Blah()

class BlahBroadcastReceiver : BroadcastReceiver() {

@Inject
lateinit var blah: Blah

override fun onReceive(context: Context, intent: Intent) {
    (context.applicationContext as MyApplication).component().inject(this)
}

}
