Unregistered Registration Token - Firebase

Question

I have a project in firebase and am trying to implement push notifications, I followed the documentation but while doing tests, sending direct to firebase, it fails and error appears, "Unregistered Registry Token".

Manifest:

<service android:name=".util.appFirebaseMessagingService">
    <intent-filter>
        <action android:name="com.google.firebase.MESSAGING_EVENT" />
    </intent-filter>
</service>

<service android:name=".util.appFirebaseRegistrationIntentService" android:exported="true"> <!-- tentei com e sem esta tag-->
    <intent-filter>
        <action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
    </intent-filter>
</service>

Classes:

public class appFirebaseRegistrationIntentService extends FirebaseInstanceIdService {
    @Override
    public void onTokenRefresh() {
        super.onTokenRefresh();

        String token = FirebaseInstanceId.getInstance().getToken();
        Log.d("Token da App", token);
    }
}

public class appFirebaseMessagingService extends FirebaseMessagingService {
     //todo
}

I cannot find my error. I get the token that is in the variable token , I put in the message by choosing the single device(in the firebase console), but still, I have the error.

Answer 1

Each time you log in, a new token is generated. These using the last token generated to send the message ?

My guess is that you might be using an expired token to push the message.

I usually save the last token in Shared preferences and onCreate in the authentication part of firebase auth, write to the Realtime database in a specific node with user data. (if you want to publish the excerpt of these codes for storage of the last token generated).

FCM token (google) associate to User, at which time?

        sendRegistrationToServer(refreshedToken);
