I have subclassed SurfaceView and call #setZOrderMediaOverlay in the constructor. So it is getting called before the SurfaceView is attached to the window. But it still does not work consistently.
By "it is too bad we made that API public.", do you mean that there are known issues with using this API? It would be good to know how much to rely on it so we can look at alternatives. Since it only misbehaves occasionally, its never clear if a change in the code has actually fixed the problem or not.
