I want to implement admob banner ad and interstitial ad inside same activity in following way:
Banner ad will be always displayed at bottom of activity and when user performs few action (suppose clicks next button) then interstitial is shown.
Is it against policy?
Currently I have two methods in my mind to implement this :
1) before showing interstitial ad load banner ad, them display interstitial. after interstitial is closed display banner ad again.
2) display interstitial ad in activity containg banner ad, without hiding banner ad. Out of this two ways which one should i prefer? Will it be against policy?
