问题 I just settled my project for supporting Android Maps v2 + ActionBarSherlock, as this answer says: http://facebook.stackoverflow.com/a/13727539/689723 Ok, I was fighting for not getting the typical XML error, and I could finally get the fragment without errors.

问题 So, all bad things in the title aside, I've got a MapView (and a few other Views) inside of a ScrollView (I know, and I've advised a thousand times against putting a MapView in a scrolling container but this is what the client wants) and when I scroll the ScrollView up the MapView ends up drawing over the ActionBar .

问题 EDIT : I transferred my 20+ projects that tries to use Google Maps for Android v2. After changing keys and stuff, now, it works. I don't know what made this work, but thank you all. I got one keystore, the key is right. I guess it magically fixed somehow. Well, thanks guys. I'm doing searches for 2 days and I couldn't fix this problem.
