Libgdx's Application Life-Cycle and Interface

The Application Life-Cycle in Libgdx is a well-defined set of distinct system states. The list of these states is pretty short: create, resize, render, pause, resume, and dispose.

Libgdx defines an ApplicationListener interface that contains six methods, one for each system state. The following code listing is a copy that is directly taken from Libgdx's sources. For the sake of readability, all comments have been stripped.

public interface ApplicationListener {
  public void create ();
  public void resize (int width, int height);
  public void render ();
  public void pause ();
  public void resume ();
  public void dispose ();
}

All you need to do is implement these methods in your main class of the shared game ...
