问题
Hope you all are fine. I am trying to add in app purchases in my app.. Using google demo Trivial drive. I configure each and every thing in my play store account.. I don't know why I still am getting error retrieving information for the server. [DF-AA-20] Please anybody know the solution.. Much appreciated.. :)

As it says in the Testing in-app billing tutorial you need to upload a version of your App to the Play store and publish it (even if only to an Alpha testing track) before you can try In-app billing.
