问题
I have png images of map tiles over parts of the UK and i want to draw them on top of the google maps view, I have everytyhing set up, just want to be able to draw the tile images now.
My main class extends 'MapActivity', can i add a canvas function to draw them?
ALso, I only obviously need to draw the tiles that are in view on the phone while the tiles out of view should not be drawn.

You can add an Overlay to the MapView, that will get you a canvas to draw on. See http://code.google.com/android/add-ons/google-apis/reference/com/google/android/maps/Overlay.html
