Data flow for a purchase request with Google In-App-Billing V2 is :
The last part (CONFIRM_NOTIFICATIONS) allows developers to confirm that the item was successfully delivered to the user.
in V3, transaction is confirmed as soon as "onActivityResult()" is called. My question is : how to "cancel" a transaction when error/exception occurs ?
Thank you
There's no API to cancel a purchase through the Google Wallet Merchant. You have to do it manually.
