Answer 1

Ich fand die Lösung. Ich hatte eine GLSurfaceView-Klasse, die die Renderer-Schnittstelle implementiert. Ich habe vergessen den Renderer in meine Ansicht zu setzen.

class CustomGl extends GLSurfaceView implements Renderer{ 

    SquareImage image; 
    Context context; 
    float rquad = 0.0f; 
    public CustomGl(Context context) { 
     // TODO Auto-generated constructor stub 
     super(context, null); 


     //Set this as Renderer 
     this.setRenderer(this); //**I ADDED THIS THE PROBLEM SOLVED!** 


     this.context = context; 
     this.image = new SquareImage(); 
     Log.d(VIEW_LOG_TAG, "gl const"); 
    }
