Not getting refreshed token firebase android

Question

I have trouble in getting refreshed token in firebase. I have gone through documentation and followed the steps fro android exactly. In my log I find firebase connection as successful. Not sure why I am not getting the instance token. I am in initial stage and trying to get the token in logcat.

Answer 1

The onTokenRefresh() method doesn't trigger the first time an app Is installed. It is only triggered by specific scenarios.

To get your token, you have to call FirebaseInstanceId.getInstance().getToken() at the start of your app (like in onCreate or something).

Answer 2

From the github project of FCM here

The documentation onTokenRefresh() reads :

• Called if InstanceID token is updated. This may occur if the security of the previous token had been compromised. Note that this is called when the InstanceID token is initially generated so this is where you would retrieve the token.

You have to Clear Cache of you app or reinstall it in order to call this method.
