GLGraphics(GLSurfaceView glView) {
this .glView = glView;
}
public GL10 getGL() {
return gl;
}
void setGL(GL10 gl) {
this .gl = gl;

public int getWidth() {
return glView.getWidth();
}
public int getHeight() {
return glView.getHeight();
}
}
This class has just a few getters and setters. Note that we will use this class in the rendering
thread set up by the GLSurfaceView . As such, it might be problematic to call methods of
a View , which lives mostly on the UI thread. In this case, it's OK, as we only query for the
GLSurfaceView 's width and height, so we get away with it.
The GLGame class is a bit more involved. It borrows most of its code from the AndroidGame class.
The synchronization between the rendering and UI threads is a little bit more complex. Let's have
a look at it in Listing 7-3.
