How to inject into a BroadcastReceiver

Dagger 2 example for injecting objects into a BroadcastReceiver.

The BroadcastReceiverModule.kt

@Module
abstract class BroadcastReceiverModule {
    @ContributesAndroidInjector
    abstract fun contributesMyTestReceiver() : MyTestReceiver
}

The AppComponent.kt

@Singleton
@Component(
        modules = [
            (AndroidSupportInjectionModule::class),
            (BroadcastReceiverModule::class)
        ])
interface AppComponent : AndroidInjector<MyApp> {
    @Component.Builder
    abstract class Builder : AndroidInjector.Builder<MyApp>()
}

The Application class

class MyApp : DaggerApplication() {
    override fun applicationInjector(): AndroidInjector<MyApp> =
            DaggerAppComponent.builder().create(this@MyApp)
}

The BroadcastReceiver class

class MyTestReceiver : BroadcastReceiver() {

    @Inject
    lateinit var anInjectedObject: MyInjectObject

    override fun onReceive(context: Context, intent: Intent) {
        AndroidInjection.inject(this, context)
        anInjectedObject.doSomthing()
    }
}
