title: LibGDX on Netbeans and Android
body: <p>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.</p>
  
  <p>If someone have manged to run LibGDX on andriod by setting up the project in Netbeans, please share the steps you did.</p>
  
  <p>Some code, I doubt that would help through:</p>
  
  <pre><code>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);
      }
  }
  </code></pre>
  
  <p>The debug output I get is the following:</p>

  <p>So basically I cannot cast game.GameSystem to ApplicationListener. Even if GameSystem implements ApplicationListener.</p>
  
  <p>GameSystem works as intended on PC, all I did for the Andriod project was to put that code in the main file.</p>
