I've tried the com-admob-plugin-cordova, but i can't assure you it is working, but if you do not tried it yet i think it worth. The intel XDK emulate tab only shows blackscreen. Have all this plugins installed:
and the already mentioned com-admob-plugin-cordova
I have publish my game about a month ago on google play, but until now i just can't publish for IOS.
Any help or news will be much appreciated. Thanks!
