I've followed this post on Medium to try to implement firebase authentication: https://blog.invertase.io/getting-started-with-firebase-authentication-on-react-native-a1ed3d2d6d91
I firstly implemented the Social Authentication with Facebook and it worked fine, but after that, when I successfully finished the Google Authentication part, the Facebook part was stuck at the line
return firebase.auth().signInWithCredential(credential);
Because It didn't return the user Promise after that so the Firebase onAuthStateChanged cannot log the user in
The function that handle facebook authentication:
onLoginOrRegisterFacebook = () => {
LoginManager.logInWithReadPermissions(["public_profile", "email"])
.then(result => {
if (result.isCancelled) {
return Promise.reject(new Error("The user cancelled the request"));
}
// Retrieve the access token
return AccessToken.getCurrentAccessToken();
})
.then(data => {
// Create a new Firebase credential with the token
const credential = firebase.auth.FacebookAuthProvider.credential(
data.accessToken
);
// Login with the credential
return firebase.auth().signInWithCredential(credential);
})
.then(user => {
})
.catch(error => {
const { code, message } = error;
});
};The Facebook Sign In Method in Google Firebase Authentication Console is also enabled with enough information of my FB app, I also paste the OAuth redirect URI to my Facebook app configuration, and the Dashboard of Facebook Developer also successfully shows the installed app user.
