How to use helper class as singleton in broadcast receiver?

Question

I want to use dagger approach to for helper classes. Bellow is the code i am currently using for Activity. But i am not able to understand how should i be using this for helper class.

Where helper class is called inside a receiver.

AppComponent.java

@Singleton
@Component(modules = { AndroidSupportInjectionModule.class, AppModule.class, ActivityBuilder.class})
public interface AppComponent extends AndroidInjector<DaggerApplication> {

    void inject(MyApplication app);

    @Override
    void inject(DaggerApplication instance);

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

        AppComponent build();
    }
}

ActivityBuilder.java

@Module
public abstract class ActivityBuilder {

    @ContributesAndroidInjector(modules = MainActivityModule.class)
    abstract MainActivity bindMainActivity();

}

AppModule.java

@Module
public abstract class AppModule {

    @Binds
    abstract Context provideContext(Application application);

}

MainActivityModule.java

@Module
public abstract class MainActivityModule {

    @Provides
    static MainPresenter provideMainPresenter(MainView mainView) {
        return new MainPresenterImpl(mainView);
    }

    @Binds
    abstract MainView provideMainView(MainActivity mainActivity);

}

The above code is what i am using for activities. I am now willing to use same structure for my helper classes too. I did a plenty of research and tried some methods which were failing as my Helper class requires 2 parameter. First one is context and another is IPhoneCallReceiver. I know IPhoneCallReceiver can be accessed in @Module using @Binds, but i am having issue getting Context. Here Helper class is CallStateHelper

PhoneCallReceiver.java

public class PhoneCallReceiver extends BroadcastReceiver implements IPhoneCallReceiver {

    CallStateHelper callStateHelper;

    @Override
    public void onReceive(Context context, Intent intent) {
        callStateHelper.stateChange(intent);
    }
}

CallStateHelper.java

public class CallStateHelper extends PhoneStateListener {

    private IPhoneCallReceiver receiver;

    public CallStateHelper(Context context, IPhoneCallReceiver receiver) {
        this.receiver = receiver;
        TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        tm.listen(this, PhoneStateListener.LISTEN_CALL_STATE);
    }

    @Override
    public void onCallStateChanged(int state, String incomingNumber) {
    }
}

I want to use CallStateHelper by @Inject and want it as Singleton Class. I am very new to Dagger

I finally did it. You just have to provide DispatchingAndroidInjector<BroadcastReceiver>
