Async injection with Dagger 2 and RxJava

SplashActivity.java

public class SplashActivity {

	@Inject
	Observable<HeavyExternalLibrary> heavyExternalLibraryObservable;

	//This will be injected asynchronously
	HeavyExternalLibrary heavyExternalLibrary; 

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate();
		//...
		heavyExternalLibraryObservable.subscribe(new SimpleObserver<HeavyExternalLibrary>() {
            @Override
            public void onNext(HeavyExternalLibrary heavyExternalLibrary) {
	            //Our dependency will be available from this moment
	            SplashActivity.this.heavyExternalLibrary = heavyExternalLibrary;
            }
        });
	}
}
