The simplified source code without useless comment, imports, flourish :
The renderer :
Quote
public class ThreeDimensionsRenderer implements GLSurfaceView.Renderer{

   private FrameBuffer fb = null;
   protected World world = null;

   private ThreeDimensionsActivity master = null;
   private ThreeDimensionsActivity context = null;
   
   //Others thread can add Object3D to add or remove on scene
   /**
    * Objects to delete
    */
   private List<Object3D> toRemoveObject = null;
   /**
    * Objects to add
    */
   private List<Object3D> toAddObject = null;
   
   public ThreeDimensionsRenderer(ThreeDimensionsActivity master, ThreeDimensionsActivity context) {
      this.master = master;
      this.context = context;
   }

   @Override
   public void onSurfaceChanged(GL10 gl, int w, int h) {
      if (fb != null) {
         fb.dispose();
      }
      fb = new FrameBuffer( w, h);

      if (master == null) {
         world = new World();

         MemoryHelper.compact();

         if (master == null) {
            master = context;
         }
      }

   }

   @Override
   public void onSurfaceCreated(GL10 gl, EGLConfig config) {
   }
   
   @Override
   public void onDrawFrame(GL10 gl) {
      Camera cam = world.getCamera();
      
      //Add objects to add
      for(Object3D ob : this.toAddObject){
         world.addObject(ob);
      }
      //Remove objects to remove
      for(Object3D ob : this.toRemoveObject){
         world.removeObject(ob.getID());
      }
      
      this.toRemoveObject.clear();
      this.toAddObject.clear();
      
      //Rendering
      fb.clear(new RGBColor(100, 113, 122));
      world.renderScene(fb);
      world.draw(fb); //PROBLEM ON SECOND TIME
      fb.display();
   }

   public void addObjetToAdd(Object3D ob){
      this.toAddObject.add(ob);
   }

   public void addObjectToRemove(Object3D ob){
      this.toRemoveObject.add(ob);
   }
}
And the Activity :
Quote
public abstract class ThreeDimensionsActivity extends Activity{
   private static ThreeDimensionsActivity master = null;

   protected GLSurfaceView mGLView;
   protected ThreeDimensionsRenderer mRenderer = null;
   
   @Override
   protected final void onCreate(Bundle savedInstanceState) {
      if (master != null) {
         this.copy(master);
      }

      super.onCreate(savedInstanceState);
      this.setContentView(this.getLayoutId());

      //OpenGL config
      this.mGLView = (GLSurfaceView) this.findViewById(this.getOpenGLSurfaceViewId());
      
      this.mGLView.setEGLContextClientVersion(2);
      this.mGLView.setEGLConfigChooser(new AAConfigChooser(this.mGLView));

      this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
      
      //Renderer creation
      mRenderer = new ThreeDimensionsRenderer(master, this);
      this.mGLView.setRenderer(mRenderer);
   }

   @Override
   protected final void onPause() {
      super.onPause();
      mGLView.onPause();
      
   }
   @Override
   protected void onResume() {
      super.onResume();
      mGLView.onResume();
   }
   @Override
   protected final void onStop() {
      super.onStop();
   }

   private void copy(Object src) {
      try {
         Field[] fs = src.getClass().getDeclaredFields();
         for (Field f : fs) {
            f.setAccessible(true);
            f.set(this, f.get(src));
         }
      } catch (Exception e) {
         throw new RuntimeException(e);
      }
   }
   
   protected boolean isFullscreenOpaque() {
      return true;
   }

   public ThreeDimensionsRenderer getRenderer(){
      return this.mRenderer;
   }
   
}

We can see a comment "//PROBLEM ON SECOND TIME" : it's here that the problem appear. But only the second time.

Explanations :
1 - On my application, i start a first 3D activity... Works fine.
2 - On this activity, call an other activity (an UI activity). Works fine.
3 - And, when i press previous android button, the 3D activity should appear. But the exception arrive.

Thanks.
