    this.mGLSurfaceView.getHolder().setFormat(PixelFormat.TRANSLUCENT);
    this.mGLSurfaceView.setEGLConfigChooser(8,8,8,8,16,0);

*CocosRenderer

pGL10.glDisable(GL10.GL_DITHER);
pGL10.glHint(GL10.GL_PERSPECTIVE_CORRECTION_HINT, GL10.GL_FASTEST);
pGL10.glClearColor(0, 0, 0, 0);
pGL10.glEnable(GL10.GL_CULL_FACE);
pGL10.glShadeModel(GL10.GL_SMOOTH);

director->setClearColor(Color4F(0.0f, 0.0f, 0.0f, 0.0f));
