Ionic Google OAuth Authentication, Firebase 3 and (ngCordovaOauth plugin or cordova-plugin-googleplus)

      // for form inputs)

      // Don't remove this line unless you know what you are doing. It stops the viewport
      // from snapping when text inputs are focused. Ionic handles this internally for
      // a much nicer keyboard experience.

And can you also give an example for the controller code, or how to bind it with ng-click?

Nevermind, i finally able to do it :)

Thanks for the code thats really helpful!

Hola @jdnichollsc,
podrias decir como configuras en firebase? en tipo de aplicacion seleccionas web? yo he realizado e firebase login con facebook (seleccionando web) y en navegador web funciona perfecto pero lo pruebo en android y no me funciona.....

muchas gracias!

@ilman it's a pleasure!
@enklenke Hola man, es por eso que en mi ejemplo estoy utilizando un plugin de cordova cuando la aplicación se abre en el móvil, por lo cual funciona tanto en desktop como en el móvil! 👍

hola @jdnichollsc, el código funciona perfecto, tienes idea de como funciona el login anonimo?

I don't know about Anonymous login. Guys, my example was updated using the native way with cordova-plugin-googleplus

Where were you 6 months ago!, haha great plugin thank you for your work!.

@alxanthony haha you're welcome!
