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:
1) cordova-plugin-device
2) cordova-plugin-file
3) cordova-plugin-httpd
4) cordova-plugin-inappbrowser
5) cordova-plugin-media
6) cordova-plugin-splashscreen
7) cordova-plugin-statusbar
8) cordova-plugin-wkwebview-engine
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!
