title: How do I validate on my server that an app was successfully purchased through the Android Market?
body: <p>I have an Android app that receives premium content and I want to validate server-side that the app was purchased via the Android Market. I can used the Licensing Service to check access on the app, is there a way to connect to the Licensing Service from a server? If not, can I use Google Checkout API data to validate the purchase?</p>
