Your stacktrace gives you the answer.
Line 60 of FullScreenViewActivity you are attempting to cast an ImageView to an AdVIew.
I bet line 60 is
AdView adView = (AdView) this.findViewById(R.id.adView);
Which means that in your layout XML R.id.adView is actually for an ImageView OR you need to do a clean build.
