Hi Everybody

I have a problem and need to solve it.

I couldn't using google+ plugin to develop my Google Sign-In because Google decided to shutdown Google+ API (https://developers.google.com/+/api-shutdown). I have to try develop it manually but I have problem to view Google Sign-In in WebView in mobile app because Google wouldn't allow it again (https://developers.googleblog.com/2016/08/modernizing-oauth-interactions-in-native-apps.html).

 If you try to do that you could get this error.

Hopefully somebody can solve this problem for me. BTW thanks for your attention :)

Hello assif_tiger,

I already read that link given to me but I want some tutorial more technical. Because I have see some documentations about Google sign-in such as Google Oauth 2.0 (server side or client side), migrating from Google+ API, etc. 

But I couldn't simply implement it to OS because it's too hard for me. (FYI I stuck with this problem almost 2 weeks -_-). Would you have any solution for me??

Best Regards,
