I have been using an older version of the In-App Billing Library that Google stop supporting in January of this year. Oddly enough, customers have been able to purchase items up through last week.
However, my app now gives a "billing version is no longer supported" error when customers try to use the feature.
I have not been on this forum in a while and I am having a hard time finding an updated version of the billing library, if it exist.
Can someone direct to the billing library version that is now supported by Google? Thanks
