GoogleSignIn by Scott returning error="0" in Android

Hi! I have been trying to implement this plug in. I have been able to make it work in iOS with no problem, but in Android I haven´t been able to sign in. I´ve tried using a web id created through google console, and by using Firebase with the google-service.json incorporated into my project.

Everytime I try to sign in using the debug key (which SHA1 I have incorporated in the Firebase App settings) I received an error code 0 like this:

{
 [error] => “0”

 [isError] => true

 [name] => “googleSignIn”

}

I have ran out of ideas and can´t find what an error =“0” means.

I´m using daily build 3550 and have been testing on an Android 5.5.1 device. 

I´m I missing something?

It seem it was trying to test with the debug keystore. I have done a production compilation and it finally worked.
