Does anyone have any experience with Chartboost on Android ?
So basically when I start the app from 'cold' Chartboost works fine, I get adverts, callbacks are good etc.
If however I exit the app (press home button), then resume the app it goes wrong.
I do a loadAd and it's fine, but when I do showAd I get an error back saying 'NO_HOST_ACTIVITY'
Anyone come across that before ?
