Hey there Mr Chaz! :) Hmmm... I think I'm leaning towards just requiring people that buy my donate app to keep it on their phones and I'll look for it using the PackageManager as you suggested.

I'm making next to nothing off of this anyway, so the thought of spending yet more money on infrastructure seems a little premature at this point. - Mike On Jul 22, 5:30 am, MrChaz <[email protected]> wrote: > Assuming they still had it installed it you could just query the > PackageManager for it. > Otherwise I dunno, maybe it's possible to write stuff into the > SharedPreferences somehow > > On Jul 21, 11:34 pm, Mike <[email protected]> wrote: > > > 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?
