In Google Play, In-app Billing V.3 there is an option to check if it's supported on user device. Using isBillingSupported method.
What do I do if it's not supported. Can I send the user to update his device(If yes, so how?)? What can I do to enable him purchasing from me?
回答1:
InAppBilling v3 requires:
- Google Play client version 3.9.16 or higher
- Google Play client version 3.10.10 or higher for subscriptions
If it is not supported, I would recommend to ask the user to update its Google Play client. Another solution would be to fallback on InAppBilling V2 (requires Google Play version 3.5 or higher).
Most users are already running Google Play client version 3.9.16 or higher.
