Android :: Google Maps Force Closing

I have been trying to add a map to my application, I have followed instructions on the android developers HelloGoogleMaps tutorial but my map is just force closing when I run the maps option. I have obtained my api key logged permissions in manifest (Internet, Maps) and logged intent. When I look at the debugger the intent line always shows up but I have put in test code and the intent is fine but it seems to be saying it cannot locate the class;
