I have written code for in-app purchase but it is not working after updating to inapp-billing-v3 api.
It is saying "you have already purchased item." or something like this.
I think item is not getting consumed.
So I need to check if item is already purchased then consume before making new purchase.
Its not an big task and quote by writing "I can consume item in lower cost".
I will provide you source code and then you have to correct and send it back to me.
I will give you max 900 if you complete the project longer than 2 hours.
