问题
I am have just completed the hello-mapview tutorial and I am confused by the max zoom levels I can achieve. The documentation for the MapController class states that the zoom can go up to level 21 however I cannot seem to exceed 19. I also notice that the google Maps app from the market can go 2 extra zoom levels. Is there a way that I can get these extra two zoom levels?

Try using:
// decrement it until you get map visible...
controller.setZoom(map.getMaxZoomLevel() - 1)
