I have a paid app in the Play Store (Profile Widget, in case anyone is wondering ;)) and I want to allow some users (friends, or people who do not have a credit card) to download it for free.
Of course I could just send them the APK, but they wouldn't get the updates automatically, and with every update to the app I would have to send them all the APK file again. And also, by using this method, anyone that had access to the APK file would be able to install the app for free.
I saw that by using the Android Licensing Library you could make some users bypass the License Check, but I want the app to show as "Purchased" for them in the Play Store, and I don't think this would do it.
I searched Stack Overflow but none of the solutions I found (like creating a separate APK and checking for its existence from the "real" app) handled the auto-update part.
Has anyone found a good solution for this?
Thanks in advance!
