in app billing :- Authentication is required. You need to sign into your Google Account

Question

I am implementing app billing in my app. I have tried all the possible solutions on the stack over flow , but I am unable to succeed in what I tried. I have updated all the api keys and created product items with ids in the dev console, and I have uploaded my singed apk to my alpha but not published ,only I have saved in the drafts. And I have created tester accounts to test the app.

When I am testing in all the accounts i got the same error

Please help me to get out this problem

Thanks in advance

Answer 1

You need to publish app to test IAB . You can test even being on alpha channel.

To test in-app billing, you need to publish your app to an alpha or beta channel in Google Play.

Answer 2

to able test google IAP android, you must change your app to production or beta testing mode
