There was a post about whether someone who gets your paid app's apk file for free will be able to continue to get updates without having to pay from the Market. The thread was closed by a moderator: http://androidforums.com/android-applications/65038-can-you-update-free-paid-app.html While I can kind of understand why the moderator closed the thread, as a developer about to release a paid application, I was interested in reading what was being posted about this being true or not. So I know that my apk file is protected, but for rooted users, they can get to it, so it's inevitable that my app could end up sent around for free too. Is there some way we developers are protected in the Market against free updates? If the Market doesn't do this, does anyone know of or have any ideas about how developers could protect their updates?
