这是我与RNFB Facebook登录有关的第二个问题。

紧跟RNFB提供的official code sample。...下面的代码

问题出在firebase().signInWithCredential(facebookCredential);行上。...它没有触发Firebase监听器auth().onAuthStateChanged所有其他代码均按预期方式运行，并且已正确填充facebookCredential变量

import { firebase } from '@react-native-firebase/auth';

  onFacebookButtonPress = async () => {
    // Attempt login with permissions
    const result = await LoginManager.logInWithPermissions([
      'public_profile',
      'email',
    ]);

    if (result.isCancelled) {
      throw 'User cancelled the login process';
    }

    // Once signed in, get the users AccesToken
    const data = await AccessToken.getCurrentAccessToken();

    if (!data) {
      throw 'Something went wrong obtaining access token';
    }

    // Create a Firebase credential with the AccessToken
    //const facebookCredential = firebase.FacebookAuthProvider.credential(data.accessToken);
    const facebookCredential = firebase.auth.FacebookAuthProvider.credential(
      data.accessToken,
    );

    // Sign-in the user with the credential
    firebase().signInWithCredential(facebookCredential);
  };

我通过围绕问题线进行尝试/捕获来解决了。原来是因为我曾经使用Google登录。

An account already exists with the same email address but different sign-in credentials. Sign in using a provider associated with this email address

我们不应该允许用户使用FB或Google登录吗？？？
