  • 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?

  • Try Construct 3

    Develop games in your browser. Powerful, performant & highly capable.

    Try Now Construct 3 users don't see these ads

    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.
