Unity IAP doesn't work on Android

Hello guys, I am trying implement Unity IAP in my mobile game .In editor everything works. I have tested it just on my Android yet. So I have imported IAP from services, used script from Unity IAP implementation and attached it on GameObject in my first scene, made Alfa version with purchase product then when I downloaded game as tester and played it popup didn't show up. So I checked logCat which says there is no available product. Please do you have any ideas? Thanks for answers. In editor:
