Thanks a lot for your answer Xcept.
Paul, much appreciated as well.
Paul, What I need (and as far as I can guess some other users out there) is to know when a video (interstitial) has finished, so we can give the player something (points, coins, lives or whatever) and if I'm right, you can get the cash for showing the entire video.
As far as I know, now you can show a full screen video from chartboost but the user can close it in any moment, is this right? so you can only take the money if the user 'tap' on the video to go to whatever the link/open app store, etc.
How could I control if the user watch the entire video or not (or do whatever the stuff that Chartboost need someone do to pay)
Is there any way to do that?
Not sure if I've expressed my points and doubts.. ;P
Any help or correction will be more than welcome.
Thanks a lot again.
