How to add Admob plugin to an android proyect?

I’m trying to install cordova-admob-pro and I get some errors.

I install this plugin with this command: meteor add cordova:cordova-plugin-admobpro@https://github.com/floatinghotpot/cordova-admob-pro/tarball/ced77fcef0a36ba727678795ab1c45b0ac92dfd0

And when I’m trying to run android-device I get these error:

Error while running for mobile platforms: Error running

Installing "cordova-plugin-admobpro" for android
Fetching plugin "cordova-plugin-extension" via plugin registry

Any help?

Did you ever figure it out?
