[FIXED] LibGDX on Netbeans and Android

Issue

I am trying to run my application that uses LibGDX on Andriod using the NetBeans IDE. However the game crashes for some reason, I just got the "This application have stopped to work" message when I try to run the application. Everything works great on PC, so apparently I have missed something in the andriod set up. Setting up an andriod project on NetBeans is not an documented area and things seem to be different on Eclipse.

If someone have manged to run LibGDX on andriod by setting up the project in Netbeans, please share the steps you did.

Some code, I doubt that would help through:

public class Game extends AndroidApplication {
    public void onCreate (android.os.Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            initialize((ApplicationListener) new game.GameSystem(new Size2i(100, 100)), false);
    }
}

The debug output I get is the following:

So basically I cannot cast game.GameSystem to ApplicationListener. Even if GameSystem implements ApplicationListener.

GameSystem works as intended on PC, all I did for the Andriod project was to put that code in the main file.

Solution

Okay, I solved it now, turned out I used the wrong version of game.GameSystem.
