i need help. Im trying to start an app with Google Maps V2 integrated. On my Samsung Galaxy S2 with JellyBean it is working and on my fathers' S3 as well. But on a HTC Desire and some others it doesn't. I couldn't find out what I'am doing wrong.

Google Maps V2 supports Android version 2.2+

Google Maps V2 require installed on the your device Google Maps and Google Play Service. If your device does not contains this application your app does not work.

HTC desire by default working under Android version 2.1

You should use SupportMapFragment.

<fragment
class="com.google.android.gms.maps.SupportMapFragment"
...

Your class must extend FragmentActivity.

Also make sure you imported the below

import android.support.v4.app.FragmentActivity;  
import com.google.android.gms.maps.SupportMapFragment;
