Banner Event Listener
Banner life cycle goes as follows:
BasicEventListener.onLoaded: Called when the banner is loaded and ready to be shown. If this goes wrong, the BasicEventListener.onFailedToLoad is called.
BasicEventListener.onImpression Ad Is Shown and ready to be Clicked.
BasicEventListener.onClick A Creative of the Ad is clicked. It can be a call to action creative or not.
OpenEventListener.onOpen happens after BasicEventListener.onClick, If it opens an Intent in the App to see the advertisement.
CloseEventListener.onClose That Intent was closed and now we are back to your app.
BasicEventListener.onFailedToLoad When this occurs, the factory marks the object for deletion and then invokes this event with an R89LoadError. You can use that to know what happened.
