Authentication with google plus on Ionic

Question

Authentication with google plus on Ionic

I am trying to create a login with google plus in ionic 4 on the android platform, but it is always coming back an error [10], which according to google documentation, is a configuration error, but I did not find where I am going wrong.

What I've done so far:

I created the project in firebase and added an android project.
enabled Google Authentication on firebase console
Added a SHA-1 fingerprint on firebase console, created by terminal (linux).

Ionic login code

async doGoogleLogin(){

  this.googlePlus.login({
    'scopes': '',
    'webClientId': 'meuWebClientId.apps.googleusercontent.com',
    'offline': true 
  })
  .then(user =>{
    this.saveGoogleUser(user);

    this.router.navigate(["/home"]);
  }, err =>{

    this.presentAlert("Error Console", err);
  });

}

Whenever I try to log in, it returns an error '10', but I haven't figured out what's missing yet.

You need to correctly include the fingerprint certificate SHA-1.

Keep in mind that each PC generates a different and unique SHA-1 fingerprint. For example: if you're working on your office PC and your home PC, make sure you generate the SHA-1 fingerprint on each machine and add it to your project settings in Firebase Android.

If you added a single SHA-1 fingerprint and tried to use Google + auth from another machine, authentication will fail and you will get the famous Erro 10.

To generate a debug SHA-1 Fingerprint Key.

No Windows:

keytool -exportcert -list -v -alias androiddebugkey -keystore C:\Users\<user>\.android\debug.keystore

On Mac OSX and Linux:

keytool -exportcert -list -v -alias androiddebugkey -keystore ~/.android/debug.keystore

Default password: android

And the result will look something like this:

*****************  WARNING WARNING WARNING  *****************
* The integrity of the information stored in your keystore  *
* has NOT been verified!  In order to verify its integrity, *
* you must provide your keystore password.                  *
