AdMob can't display ads because of configChanges [duplicate]

Answer 1

To fix the problem you have to set your project build target to Android 3.2 or higher, see the requirements section in the documentation (Android tab).

Answer 2

You can also just ignore the newer configchanges setting and make it like the old version has:

configChanges="keyboard|keyboardHidden|orientation"

This is what I always had in my admob ad activity. The new stuff is propably for android 3+.
