        }

    }
}

I have the in app product on my developer console, and I give the permission in manifest file.

At the first time, it runs very well, but when i trying to remove the purchase by pressing the 'use button' and run it again, it gave me "Error, you already own this item" message.

Can anyone give me a solution for this issue?

Answer 1

You are getting this problem because the product is not getting consumed. Because you can only buy a product another time after its consumption.

Please check your consume button code.

Also i would recommend you to use the latest inAppBilling API's
