Q: Admob "The following classes could not be instantiated: - com.google.ads.AdView" Android XML Issue Im trying to get the google admob sdk integrated to display ads in an android application writen in xml. Yes I have already made sure that admob jar is checked in order and export under build path!
I realize there are other open questions but none of the answers solved my issue! Im getting no errors, my project.properties is set to target 19 and my manifest has this:
 <activity android:name="com.google.ads.AdActivity"
           android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>

A: I had the same issue. There are some issues with the Graphical Layout when you are rendering layouts in Eclipse for Android-19 (KitKat). You cannot change items in the Properties window for example.
Switching to Android-18 in Graphical Layout (green Android top-right) solved the problem for me.
