The map tiles probably aren't appearing because you're behind a proxy
at your office. The emulator has some issues working behind a proxy,
for more information on this take a look at
http://groups.google.com/group/android-developers/browse_frm/thread/3042e0626f197f95
on the Android Developers forum.
The problem with the zoom is probably that the map isn't ready yet to
receive that event. You probably want to wait to adjust zoom until the
map does some basic loading. Check that MapView.canCoverCenter()
returns true and that MapView.getLongitudeSpan() and
MapView.getLatitudeSpan() return non-zero values.
