Firebase push notification onTokenRefresh

Getting Started Newbie Questions
#1

Sometimes for certain reasons the push notification token of certain users expire and get replaced with a new one

Monitor token generation

The onTokenRefreshcallback fires whenever a new token is generated, so calling getToken in its context ensures that you are accessing a current, available registration token. Make sure you have added the service to your manifest, then call getToken in the context of onTokenRefresh, and log the value as shown:

@Override public void onTokenRefresh() { // Get updated InstanceID token. String refreshedToken = FirebaseInstanceId.getInstance().getToken(); Log.d(TAG, "Refreshed token: " + refreshedToken); // If you want to send messages to this application instance or // manage this apps subscriptions on the server side, send the // Instance ID token to your app server. sendRegistrationToServer(refreshedToken); }

onTokenRefresh is useful so you can update the token stored on your server without requiring the user to open the app

How can I achieve this in corona sdk ?

I don’t know whether the getDeviceToken() function get’s the updated token or not,

But i wouldn’t worry so much because if you are using the old token to send FCM notification, FCM will report a new token in its response. Of course the old token still works (in my case). I think it is like a ‘mismatch’ keyword or something like that (you can see it in the FCM docs).
