I have been able to implement In-App Billing for my product that offers subscription .
My issue is that My security related classes are on my Server .The device sends me verifications and I approve it if it is has valid public key.But is it possible to implement a communication between Market and Server so that I can cross check the response sent to me by Device with Market.
It can be anything like toe nonce or userID,device ID does the market keeps the track of it( I believe it does) and is it possible for me to retrieve it.
I believe it is possible when we implement Licensing but could not find anything about INApp Billing.
