I uploaded the APK to Amazon and pushed it to my Fire Tablet from the Live App Tasting Service, Now the Login works but the game crashes when the Amazon Login Banner pops up. The same APK when installed through USB works fine but won't login. I thought it might be a problem with my security profile but it looked OK as far as I can tell. Has anyone else seen this and if so how did you fix it. Perhaps I'm using the wrong Game Circle API. Does anyone know which code to put in when using the Export Android APK compiler. Google Play was easy to figure out, but Amazon has so many numbers.
