问题
I am using MotoDev Studio for Android Development and I am trying to Extend my Activity from MapActivity. But MotoDev does not Allow me to do this.
Can any One Tell me why this is so? On the other hand in Eclipse this is possible for me using Google Api. Plz Help me out.
回答1:
MOTODEV Studio doesn't prevent you from extending classes. It's just Eclipse + ADT and some other plugins that we created. I would advise following the direction that @PeterKnego mentioned. Just add the external library in MOTODEV Studio just as you would in Eclipse, using "Properties->Java Build Path".

I don't use MotoDev, so I can only guess what the problem might be:
MapActivity is not a part of the Android SDK - it's a part of an external library: http://code.google.com/android/add-ons/google-apis/maps-overview.html
You should include this library in your project.
Most probably the official SDK & plugin does that automatically, while MotoDev does not.
