I have downloaded the library to the one attched to thread googleplaybilling-in-app-purchases.109945
and added CreateResourceFromFile(Macro, GooglePlayBilling.GooglePlayBilling) to the Mainfest.
However the Libraries Manager is still stating that GooglePlayBilling is at version 1.11 and Online there is 5.0 whith a link that just get me to the 109945 thread.
(When I try the sample attached to the thread it displays the same.)
And When uploading to Google Play it just says:
"We've detected this app uses an unsupported version of Play billing. Please upgrade to Billing Library version 4 or newer to publish this app."
I notice that the GooglePlayBilling.zip have both the jar and xml plus the billing-5.0.0.aar file in it.
I have placed them all in the Additional Libraries folder. Is that confusing my B4A ?
