This extension enables you to use Google In-App Billing in your App Inventor app for Products (both non-consumable and consumable) and Subscriptions. The new version 3 was completely rebuilt and uses directly the Google Billing API V3.0.3.
Everyone who bought the billing extension in 2020 or 2021 will be able to download the new version for free. Please send me an email together with a proof of your purchase and your Google account and I will send you the download link. Of course you are invited to donate a small amount in case you like my work. Thank you.
I just manually sent you the download link to your Google account …
I understand what you are saying but as this extension is for making money it’s good that it need to be paid for. Also it’s unique and takes time and effort to make so the developer should be rewarded.
