Android In-App Billing v3: “Can't perform operation: queryInventory”

Question

I have setup In-App Billing for the first time using the new v3 API. It is working correctly on my devices but I have received a lot of error reports from other users.

Answer 1

I found out! It's about the version of the user's Google Play Store app. In-app billing V3 needs 3.9.16 or higher (http://developer.android.com/google/play/billing/versions.html). I used an older version and I received that error, now on 4.4.21 its ok!
