I am building an application that at some point involves In-App Billing.
To add a level of security, after an item is successfully purchased, a server will ask Android Market if the item was purchased by a specific user.
Is there any API (Java, C, any language) that would allow the server to query Android Market if a purchase was successful?
Regards
Pretty sure that would be in In-App billing itself i.e “after the item is successfully purchased” means that the user has bought it, no further checks would be needed.
