I'm developing an Android application which is using Google Maps API v2. When I run it on my Sony Xperia P it works fine. I tried to run it on another Xperia P and HTC One X and it works alright. But when I try to run it on different device (so far I've tried with two different devices), it crashes.

Here's the what I get in the LogCat when I try to run the application on a Sony Xperia Tipo:

EDITED: Problem solved. Google Location Services should be enabled.
