Testing android in app billing doesn't show any products when bebugging

Question

I have a simple app that has an unlock feature in it. When a user purchases this they can unlock more content in the app. When I debug the app I don't get any errors, but I am unable to retrieve a list of products using the google billing services. On my main activity I would like to check if the user has all ready purchased the "upgrade" if they have do something with that information.

I have been following the api documentation but its not really helping.

In App Billing Reference

Implementation

Testing

I have 1 item in my In-app products, I have followed the testing document and added an apk to my Alpha testing. The problem here is that apk cant have debugging enabled, so when I use the debugger in android studio the app may perform differently?? I think my code is OK,but any help or guidance in how to test this would be great.
