Application Error : This version of the application is not configured for Market Billing

Question

Since a couple of days it\'s possible to use in-app-billing in Android apps. Very cool of course. So, I started working on a update for my application to implement this. But

Answer 1

I also ran into this problem. I finally realized that my published app had a versionCode of 3, my draft (unpublished apk with the Billing permission) had a versionCode of 4, and the signed apk I was using to test in-app billing was still at versionCode 3. Once I changed the versionCode to 4, I was able to get through to the actual in-app product page for the purchase I was requesting.
