Google Maps Android API gives a NoClassDefFoundError

Question

My app just consists of a map with an overlay, but when I create my MapView, my app crashes with a NoClassDefFoundError. I'm using the Google API AVD that matches my target, but apparently I'm still doing something wrong. Any ideas?

EDIT: In case it helps, my NoClassDefFoundError is complaining about [generic]. I can understand why there's no class definiton for [generic], but I'm not sure where that's coming from.

Also, a later ClassNotFoundException complains of com.google.android.maps.MapView in loader dalvik.system.PathClassLoader[/data/app/mathphreak.cellmap-1.apk], and that then goes on to cause a different NoClassDefFoundError for java.lang.NoClassDefFoundError: com.google.android.maps.MapView.

Make sure you have included the following line in your application manifest:

<uses-library android:required="true" android:name="com.google.android.maps" />

and make sure it's in the correct place. My problem (had similar error messages) was that I had put this in there but like the uses-permission stuff it was just under the root element manifest, when in fact the uses-library element is suppose to be placed under the application element. In case I wasn't clear enough see the part: Configuring the application manifest from Sameers link.
