How to get Bitmap of MapView from Android Google M

问题:

I'm updating my app to the new Android Maps API V2 and ran into a problem when trying to get a bitmap image of the currently shown map. In API V1 I did this like so:

Bitmap mBitmap;
MapViwe mMapView;
// ...
mBitmap = Bitmap.createBitmap(MAP_WIDTH, MAP_HEIGHT, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(mBitmap);
mMapView.draw(canvas);

Whilest in API V1, this got me a bitmap of the map, in API V2, all I get is a black rectangle.

Also with API V2 I'm using the MapView, not the MapFragment so this isn't the problem.

GoogleMap.snapshot() method does the job.
