Use case goes like this: 1) Dev puts game for sale on Android market hoping to make lots of $$ $. 2) Dev makes $50 in a month, cries a little, realizes his game is languishing in the ratings so makes it free. 3) Game does really well and gets > 50,000 downloads. 4) Dev still wants to make some $$$ off his game, so adds a "donate" feature to app which points users to another app dev has created in the marketplace where they can donate by buying the app. 5) Dev wants to reward those who have donated by providing new features only to them.
So... how do I go about determining if any given user has purchased either my original app, or my "donate" app so that I can unlock functionality? I'd like to determine this even if the user no longer has the app installed on their phone. Then android market app seems to know this which is how it knows not to charge the user again for the same app they've already paid for. - Mike --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
