Have you gotten a Google Maps API Key? Your maps will not show until you obtain one of these from Google. Here is the link in case you have not. http://code.google.com/apis/maps/ you can obtain a debug one to get you started. Once you have it, you will need to put the key in your xml file for the mapview.
android:apiKey="API Key Goes Here" android:clickable="true" the clickable option allows your users to scroll around the map.
