I'm using the plugin made by AppGyver: https://github.com/AppGyver/phonegap-admob-plugin
The steps below replicate the crash:
1) Create an interstitial ad - createInterstitialView
2) Request the ad - requestAd
3) 3-5 seconds pass, then it crashes
I also made sure that the ad is indeed interstitial and not a banner ad. I even tried changing the specific ad type on AdMob's settings. So there are 3 types of interstitial ads: Text, Image and Video. I tried it with all of them, and even did each one individually as well. Nothing has worked, they all make the app crash. Also just to mention, I am building the app as an ad hoc build because for some reason building it as a custom scanner app doesn't display ads whatsoever.
Fortunately I got banner ads to work, but I really need interstitial ads for my app. If anyone has got interstitial ads to work on Android, I would really appreciate the help.
(Side note, I think this individual has had the same problem: https://github.com/AppGyver/steroids/issues/908. "Harsaharsa" said it might be due to Supersonic's MPA structure, but it sounded like he wasn't sure.)
