FCM - onTokenRefresh () is never called

Question

I followed the setup process as directed for Firebase Cloud Messaging. But for some reason, onTokenRefresh is never called.

The following are the changes in this regard:

app build.gradle:

 dependencies { ... compile 'com.google.firebase:firebase-messaging:9.4.0' } apply plugin: 'com.google.gms.google-services' 

project build.gradle:

 dependencies { classpath 'com.android.tools.build:gradle:2.1.2' classpath 'com.google.gms:google-services:3.0.0' } 

AndroidManifest.xml

 <application ... <service android:name="com.blynq.app.services.MyFirebaseMessagingService"> <intent-filter> <action android:name="com.google.firebase.MESSAGING_EVENT"/> </intent-filter> </service> <service android:name="com.blynq.app.services.MyFirebaseInstanceIDService"> <intent-filter> <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/> </intent-filter> </service> </application> public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService { @Override public void onTokenRefresh() { String token = FirebaseInstanceId.getInstance().getToken(); Log.i("FCM", "Token refreshed - " + token); registerTokenWithServer(token); } } 

Log state I/FirebaseInitProvider: FirebaseApp initialization successful , but onTokenRefresh () is not executed.

Of course, I missed something, but I could not understand where.

EDIT: In the case of emulators only, the Android device did a great job with the above settings.

FCM clients require devices running Android 2.3 or higher, which also installs the Google Play Store app or runs the Android 2.3 emulator with the Google API.
