I see this in my application in the Google Play console:
It was detected that your application uses an earlier version of the Google Play Developer API. Versions 1 and 2 of this API will no longer be available as of December 2019. Update it to version 3 before that date. Ten that this notification does not have any relation with the cancellation of the billing library and AIDL
