FirebaseMessagingService 11.6.0 HandleIntent

The FirebaseMessagingService has the method onMessageReceived() which we should override to handle notifications, but this only works when the app is in Foreground.

To handle notifications even when the app is in background, I used to override the handleIntent, to just call the onMessageReceived().

In FirebaseMessagingService 11.6.0, the method handleIntent became final, with that said, I can't override it as I was doing.

How should I handle notifications when my app is in background in the 11.6.0?

public class NotificationsListenerService extends FirebaseMessagingService {
    private static final String TAG = "NotificationsListenerService";

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) 

        String notifyData = remoteMessage.getData().get("notifData");

        if(notifyData.contains("|")){
            String[] itens = notifyData.split("\\|");
            notifyData = itens[0];
        }


        String notifyType = remoteMessage.getData().get("notifType");
        String title = remoteMessage.getData().get("title");
        String message = remoteMessage.getData().get("body");

        if(!isAppInForeground(App.getContext())){
            sendNotification(title, message, notifyData, notifyType);
        }
    }

    @Override
    public final void handleIntent(Intent intent) {
        ...
        this.onMessageReceived(builder.build());
        ...
    }

    private void sendNotification(String messageTitle, String messageBody, String notifyData, String notifyType) {
        ...
    }


    //Detect if app is in foreground
    private boolean isAppInForeground(Context context) {
        ...
    }
}
