in app billing fails in new version of my app

Question

My app has been in the play store for a while, and it worked. Yesterday I released an update, and found a bug in it, which I want to fix today. After uploading my alpha apk

Answer 1

You are suppose to sign your APK with your live certificate. Then install that into your device and test InAppBilling.

If you are using the android.test.purchased it will work all the way, but you won't have the developerPayload in your final response.

If you are using your own draft in app item you can test all the way but you will be charged and so will have to refund it yourself afterwards.

You cannot buy items with the same gmail account that you use for the google play development console.

Answer 2

As I suspected, I just had to wait a couple hours. :(

edit:to give a bit more info, this is the same thing that happens when you buy an in app item on one device, and the other device with the same google account is not in sync for a while. It's just that the google servers are not updated fast enough.
