push notification - Android - FirebaseApp / Firebase-Initialization is not starting

Question

I want to implement the Firebase-Messaging plugin into my Android-App. I've started with the "quickstart-android-master/messaging"-example from github: https://github.com/firebase/quickstart-android/tree/master/messaging

This works for me! Log-Output:

D/FirebaseApp﹕ com.google.firebase.auth.FirebaseAuth is not linked. Skipping initialization.
D/FirebaseApp﹕ Initialized class com.google.firebase.iid.FirebaseInstanceId.
D/FirebaseApp﹕ com.google.firebase.crash.FirebaseCrash is not linked. Skipping initialization
D/FirebaseApp﹕ Initialized class com.google.android.gms.measurement.AppMeasurement.
I/FirebaseInitProvider﹕ FirebaseApp initialization successful

But if I want to implement the Plugin "com.google.firebase:firebase-messaging:9.0.2" into my app, the FirebaseApp isn't initialized! So the FirebaseApp plugin isn't starting! - No Log or token received!

I've also added apply plugin to build.gradle file in "app"-directory:

    apply plugin: 'com.android.application'

android {
  // ...
}

dependencies {
  // ...
  compile 'com.google.firebase:firebase-messaging:9.0.2'
}

// ADD THIS AT THE BOTTOM
apply plugin: 'com.google.gms.google-services'

And the google-services plugin to build.gradle in the "root" directory:

buildscript {
    // ...
    dependencies {
        // ...
        classpath 'com.google.gms:google-services:3.0.0'
    }
}

Problems could be:

• AndroidAnnotations, Proguard, Product flavors...
