Firebase Cloud Messaging -> Illegal State Exception in Android

Question

I am trying to make an app based on Cordova that is able to send Notifications via FireBase Cloud Messaging

Here the MainActivity.java

  public class MainActivity extends CordovaActivity
{

@Override
public void onCreate(Bundle savedInstanceState)
{
    Intent i=new Intent(this,NotificationService.class);
    startService(i);
    super.onCreate(savedInstanceState);
    // Set by <content src="index.html" /> in config.xml
    Helper mhelper=new Helper(this,appView);
        FirebaseMessaging.getInstance().subscribeToTopic("Testing");
        Log.d("Message","Subscribed To Testing");


    Log.d("Token",FirebaseInstanceId.getInstance().getToken());
    loadUrl(launchUrl);


}
}

However I am getting a Illegal State Exception at Line 49:

    FirebaseMessaging.getInstance().subscribeToTopic("Testing");

The rest Manifest.xml etc. are the same as the sample provided here https://github.com/firebase/quickstart-android/tree/master/messaging

In the Logcat, the error it is showing is::

I tried java.lang.IllegalStateException: FirebaseApp with name [DEFAULT] but still it doesn't recognize FirebaseDatabase Class

@USKMobility I tried that too. But I am not using Firebase Database. So there isn't any class present in my library — Yash Jain, May 28 '16 at 17:24
I am not an expert in Cordova and its build system, but firebase sdk requires gradle androidmanifest-merge feature to add extra components (defined in the firebase libraries) to your androidmanifest.xml file. Can you check that your final AndroidManifest includes a content-provider created by Firebase ? — Diego Giorgini, May 29 '16 at 18:27
I think I figured it out. I think Fcm and Gcm take some time to get tokens.. If I try to do anything with cloud messaging without the token being assigned I will get error — Yash Jain, Jun 09 '16 at 13:56

Try updating your dependency to:

compile 'com.google.firebase:firebase-messaging:9.0.2'

This bug was fixed in patches between 9.0.0 and 9.0.2
