One effective way I have ever considered is: Market application maintains a list which contains the buying information for all the applications. Example: App foo: packageName;orderNumber;...
Market check the list period: check all the order number with the google count in the mobile; if the orderNumber empty or illegal, check the app state: if not free, unstall it. For a better convenience, market app should at least check the app after 2 days the user install it. What's your idea? Thanks!
