Hi, when I use Unity3d mobile ads android sdk. I encounter a problem. There is no method to trigger ads OnClick event. I need this method to finish some action. I integrate GoogleMobileAds, there is a method named: AdLeftApplication;
The method you may be looking for is AdExpanded(string message). This method is called after a user clicks on an expandable ad and after the ad expands. If you just want to know when the current activity has moved to the background you can simply override the default onPause method.
