Android Maps V2 Application Crashes on Android Phone

问题

I have made an app that uses Google Android Maps API V2 and I have followed every step in the guide provided by Google but it doesn't work unfortunely and it crashes every time I try to start it up, I have looked up similar problems here on stack overflow but I haven't find one that helps me unfortunately( and yes I am using an Android Phone and not a Emulator).

The issue seem so be with it not finding MapView from the Google Play Services library even though i have added that library to my application, som I'm wondering if anyone of guys have had the same problem and how did you solve?
