Firebase Android - Skipping initialization

问题

I am currently implementing an Android app, which uses Firebase Cloud Messaging. I've implemented everything according to the tutorial on the Firebase page.

However, whenever I try to run my app it seems like the Firebase initialization fails. Both, on an emulator and on a real device I get this debug message:

D/FirebaseApp: com.google.firebase.auth.FirebaseAuth is not linked. Skipping initialization.
W/InstanceID/Rpc: Found 10010
D/FirebaseApp: com.google.firebase.crash.FirebaseCrash is not linked. Skipping initialization.

It doesn't call the InstanceIDListener. And it strangely worked with the emulator once.

You have to add the following to your android manifest:

<service android:name=".MyFirebaseInstanceIDService">
    <intent-filter>
        <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
    </intent-filter>
</service>

I'm not sure, but I guess you missed:

FirebaseApp.initializeApp(getApplicationContext());
