Interstitial must be preload in advance
Admob are still telling us that our apps (version 4.4.0) not respecting the rules of Interstitial. The consequence is ending showing ads on these apps.
I mentioned this problem before. The Interstitial must be preload in advance, not between activities.
In other words, the interstitial loads on the main activity invisibly. And when the user clicks on a button, the interstitial shows, and after that the activity starts.
