To save the APK file, you must build it by switching platforms in Unity, filling in the Build Settings and pressing 'Build'. To download from the Google play store without paying: Setting up Alpha/Beta tracks through your Google Play Developer account: Here is a link on migrating from Google Play to Amazon: In Unity press Window->Unity IAP->Android then your target. If you don't have IAP I'm not 100% sure if you will need a separate APK, but if you have in-app purchases you will need 2 different APK builds, one for each store. You will need a developer account for the Google Play Store and a developer account for the Amazon App Store. Your questions are more Google/Amazon related than Unity but hopefully this info helps:ĭo I need more then one Android Developer Account? Is it all within the same account?
