Ok I got them working, but there is a problem and I'm not sure if it C2 or CJS.
My game is compiled with the online compiler. I'm loading my debug apk onto my device and using eclipse to debug.
I have Show FullScreen Ads on my start of layout. First time I go to the layout it fires, I see mopub doing it's thing in the debugger. However, every time I leave the layout and come back to it, it never fires again. Is the Show FullScreen Ads action on suppose to fire once per game session?
Thanks.
