I'm new to Google Maps API and I'm trying to display a map in my application. Every try has failed, I don't understand why.
Here the logcat.

Have you got any idea to solve this problem?
P.S. sorry for my bad english...
Because You writing your application targeting SDK 9, and you use SupportMapFragment (as you should) in your XML file. Then you have to use getSupportFragmentManager and SupportMapFragment method.
Like that:
map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
instead of this:
mMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
