FCM Token is not generating in some android devices

I was having issues in GCM, so i migrates to FCM but I am still getting issues related to token.

I launched my updated app and I checked that there is 300 new users, 200 of them are getting tokens and 100 are not getting any token, it's a very critical issue.

Any Solutions of null token?

Solution

  • You get your FCM token from MyInstanceIDListenerService class onTokenRefresh() method on every fresh installation.

    Or you can also get FCM token with this line of code:

    FirebaseInstanceId.getInstance().getToken();
