I see you have stumbled on my Google Maps Guide. Well fist of all if you minSDKVersion is 14, there is no point in using the FragmentActivity and SupportMapFragment objects, you can just change them to a simple Activity and a MapFragment.

Second if you followed all the steps of this guide and you still have a problem of a blank map with zoom controls I would suggest you to go over this guide as well:

Google Maps API V2 Key

and make sure that you produced the key and configured it correctly in the Google API Console.
