        showProgress();
    }
}

this is the login activity code in which I'm getting an error that cannot find symbol class FirebaseInstanceIdService I have attached an image for reference

this is for my final year project which is a chatting based application because of this process, I cannot able to generate APK but Gradle sync is successful.

`FirebaseInstanceIdService` is deprecated. You should use `FirebaseMessagingService` — Md. Asaduzzaman, Jan 16 '20 at 09:50

Developers are stuck with the problem of deprecated FirebaseInstanceIdService, So now what to do?

FirebaseInstanceIdService

This class was deprecated. In favour of overriding onNewToken in FirebaseMessagingService. Once that has been implemented, this service can be safely removed. That means no need to use FirebaseInstanceIdService service to get an FCM token. You can safely remove FirebaseInstanceIdService service

Now we need to @Override onNewToken() get Token in "FirebaseMessagingService".

Sample Code:

    public class MyFirebaseMessagingService extends FirebaseMessagingService {

        @Override
        public void onNewToken(String s) {
            super.onNewToken(s);
            Log.e("NEW_TOKEN",s);
        }

        @Override
        public void onMessageReceived(RemoteMessage remoteMessage) {
            super.onMessageReceived(remoteMessage);
        }
    }

In AndroidManifest.xml

    <service
            android:name=".MyFirebaseMessagingService"
            android:stopWithTask="false">
            <intent-filter>
                <action android:name="com.google.firebase.MESSAGING_EVENT" />
            </intent-filter>
    </service>

Get Token in your Activity : .getToken(); is also deprecated if you need to get token in your activity then use as following:

    FirebaseInstanceId.getInstance().getInstanceId().addOnSuccessListener( MyActivity.this,  new OnSuccessListener<InstanceIdResult>() {
         @Override
         public void onSuccess(InstanceIdResult instanceIdResult) {
               String newToken = instanceIdResult.getToken();
               Log.e("newToken",newToken);

         }
     });

I hope you will get your solution here.

how about using onComplete(@NonNull Task task) ? – Yohanim Mar 17 '21 at 08:24 — Yohanim, Mar 17 '21 at 08:24
