Since Google decided to stop support for the older AdMob api from the 1st August 2014, I decided to update my plugin to the very latest api and add some enhancements. The plugin now supports both Android and iOS. It also supports Immersive Mode in Android!
The plugin is now based on the official AdMob for Unity plugin released by Google but makes the process of incorporating the plugin into your game much easier.
Note that existing users of my AdMob plugin will need to upgrade to the latest version before they release any updates to their game.
Simply email me with proof of purchase and I will send you a link to the latest version.
The new AdMob plugin can be found here.
