As far as I understood in IAB v3 it is required that the APK is published, if not life at least in the Alpha channel.
I'm getting an BILLING_RESPONSE_RESULT_DEVELOPER_ERROR (5), when calling getSkuDetails. As this is my first-time implementation of in-app billing, I really need to debug to know how it works, what I'm getting back, and write code according to the results.
But if the APK is required to be published to get some results from getSkuDetails, how I am suppose to debug, test, and write code at all?
Thanks
Note that one of the reasons for "Developer Error 5" is wrong data passed to getSkuDetails() - in my case we were passing a list with 6 elements but the last one was an empty string.
