How to get One Signal unique user id in Mobile?

Got the unique Id of OneSignal by using the following code which is in official site of OneSignal.

OneSignal.idsAvailable(new OneSignal.IdsAvailableHandler() {        @Override        public void idsAvailable(String userId, String registrationId) {            Log.d("debug", "User:" + userId);            if (registrationId != null)                Log.d("debug", "registrationId:" + registrationId);        }    });
