InApp purchase dont working

I imported unity inapp purchases and analytics assets to my project. I make one non consumable in app, I exported the product by csv file and upload it to my google play account for alpha test.

The purchase shows ok in the debug log of unity editor, but in the android device nothing happens! My code:

I'm very stressed about this problem :(
