There is a bug in build 2014.2432. When trying to initialize Vungle ads, the following error is showing in the app (when compiled and run on the device):
Runtime Error
java.lang.NoClassDefFoundError: com.vungle.publisher.FullScreenAdActivity
Looks as if a class is missing and I filed a bug report under case 35621.
Initializing Vungle works fine with build 2014.2428.
Please fix!
