Can't log back in after logging out: "This account already exists on your device"

[Robo-Rin]

I'm able to sign in just fine, but when I sign out and attempt to sign in again it says "This account already exists on your device". I'm never given an option to sign in from an existing account. What am I doing wrong?

Here's my setup:

import React, { Component } from 'react';
import { Alert, Button, Image, Text, View } from 'react-native';
import {GoogleSignin, GoogleSigninButton} from 'react-native-google-signin';

export default class LoginScreen extends Component{

  constructor(props){
    super(props);
    this.state = {
      user: null
    }
  }

  componentDidMount() {
    this._setupGoogleSignin().then(() => console.log('Mounted & Google setup complete.'));
  }

  async _setupGoogleSignin() {
    try {
      await GoogleSignin.hasPlayServices({ autoResolve: true });
      await GoogleSignin.configure({
        webClientId: '[my app id].apps.googleusercontent.com',
        hostedDomain: 'somedomain.com'
      });

      const user = await GoogleSignin.currentUserAsync();
      console.log('User: ',user);
      this.setState({user});
    }
    catch(err) {
      console.log("Play services error", err.code, err.message);
    }
  }

  _signIn() {
    GoogleSignin.signIn()
      .then((user) => {
        this.setState({user: user});
        console.log('Signed in');
        console.log('User: ',user);
      })
      .catch((err) => {
        console.log('WRONG SIGNIN', err);
      })
      .done();
  }

  _signOut() {
    GoogleSignin.revokeAccess().then(() => GoogleSignin.signOut()).then(() => {
        this.setState({user: null});
        console.log('Signed out');
      })
      .done();
  }

  render(){

    if (!this.state.user){
      return (
        <View style={{flex: 1}}>
          <View style={{flex: 1.5, alignItems: 'center', justifyContent: 'center', marginTop: 40}}>
            <Image
              style={{width: 156, height: 156, resizeMode: 'contain'}}
              source={require('../../assets/img/google_logo1600.png')} />
            <Text style={{fontSize: 32, fontWeight: 'bold'}}>
              Google Identity
            </Text>
            <Text style={[{fontSize: 15, paddingTop: 5}]}>
              To continue, please sign-in.
            </Text>
          </View>
          <View style={{flex: 1, alignItems: 'center', justifyContent: 'center', marginBottom: 40}}>
            <GoogleSigninButton
              style={{width: 312, height: 48}}
              size={GoogleSigninButton.Size.Wide}
              color={GoogleSigninButton.Color.Light}
              onPress={() => this._signIn()}/>
          </View>
        </View>
      );
    } else {
      return (
        <View style={{flex: 1}}>
          <View style={{flex: 1, alignItems: 'center', justifyContent: 'center', marginBottom: 40}}>
            <Button style={{width: 312, height: 48, backgroundColor: '#4385F2', color: 'white'}} title="Log Out" onPress={() => this._signOut()} />
          </View>
        </View>
      )
    }

  }
}

Thanks!

I just had to remove the hostedDomain option. Looks like the domain you choose to enter here excludes it from the list of google accounts to select from for logging in again.

Still seeking help for using hostedDomain in #277
