Google OAuth Firebase Native

I´m trying to setup GooglePlus Auth with Firebase for my app and I´m following these tutorials :

I´m trying to catch as many informations as I can from those tutorials.
But somehow when I´m trying to sign in I get a error in the console which says : ERROR 10
I´m debugging with Genymotion and using Chrome for inspection.

I tried and checked the client ID millions of times switch them up 100 times. Quite frustrated right now.

Any advice what it could be ?

I got the same error. Did you get any solution?
