        ParseInstallation installation = ParseInstallation.getCurrentInstallation();
        installation.setDeviceToken(token);
        //even though this is FCM, calling it gcm will work on the backend
        installation.setPushType(PUSH_TYPE);
        installation.save();
        PLog.d(ParseGCM.TAG, "GCM registration success");
      } catch (Exception e) {

      }
      return null;
    }
  });
  return true; // Answers the question: "Is there still work going on?"
}
