Hey,
I've created such a quite ugly but useful App.
Durch Eingabe einer Mindestspielerzahl und der URL des Gametracker-Servers ist es möglich, eine Benachrichtigung zu erhalten, wenn der entsprechende Gametracker-Server die Mindestspieleranzahl erreicht hat. Dabei prüft die App alle 15 Minuten im Hintergrund, ob die Mindestspieleranzahl...
play.google.com
Just type in the URL of the Gametracker-Server (in this case
https://www.gametracker.com/server_info/158.69.118.94:15567/) and a count of minimum players. By activating the notifiations in the app, you'll get a notification if there is your defined minimum player count on the server.
This app checks the player count every 15 min. After a start-up of your phone, it should start automatically.
There is still a little bug with the "only in Wifi"-button, but it will be fixed with the next Update.
If there are any other bugs or problems except any design issues (I really hate to design an app), it will be nice if you post them right here so i can maybe fix them
I hope, it will help you!
Best regards
