I released a game that uses Unity's built in IAP and it worked perfect. After adding gamecircle to the game, it will crash with an Unable to instantiate receiver com.amazon.inapp.purchasing.ResponseReceiver error when I cancel or press back during a purchase.
Been trying to mess with the Android Manifest file changing it to but it still crashes with the same error.
I'm using the default AndroidManifest file in the Plugins/Android folder with the added Game Circle parts the configuration setup provided. And of course my package name in the actual manifest.
Any help? Do I need to include that in the manifest at all since Unity is handling it? Anything else I might be missing?
