Needs to authenticate when using IAP

I am making a mobile game with Construct 2, and using to Intel XDK to build it for Android Crosswalk. I have added the official IAP plugin in C2. I have added the product in my developer console, and "on start of layout". I have also added the "BILLING" permission in XDK.

Anyhow, when I click the button where it should buy the in app product, it says that I need to log in to my Google account to authenticate. Any ideas how to fix this?

I Have the same problem. C2 IAP (as test mode) -> Intel XDK Crosswalk build -> upload to Android Dev as Test Alpha release -> set the in app id as the same of the c2 project -> install on my device the xdk arm build.... when i try to buy -> "Authentication is required. You need to sign into your google account".

i'm going crazy... please help me

Tried to add Cranberry IAP to an app in production, so seems like it won't work while testing. Anyone confirm?

Have you tried it as an exported project hosted on a web server?

This topic is for mobile and not web. Maybe the official IAP don't work for mobile? I know the official Google Play plugin isn't optimized for mobile.

Mobile is web. All of the mobile websites are hosted on web servers just like everything else.

Crosswalk apps are stored on the phone, not the web.
