com.firebase.ui.auth.FirebaseUiException: Provider error - Firebase-UI Authentication Facebook login not working

Question

I am using Firebase-UI authentication using e-mail, facebook, and google providers. E-mail and Google sign in work fine but Facebook sign in is not working.

My facebook and firebase dependencies:

//Firebase
implementation 'com.google.firebase:firebase-core:16.0.1'

//Cloud Firestore
implementation 'com.google.firebase:firebase-firestore:17.0.2'

//Firebase Authentication
implementation 'com.google.firebase:firebase-auth:16.0.2'

//Firebase built-in Auth UI
implementation 'com.firebaseui:firebase-ui-auth:4.0.0'

//Firebase Storage
implementation 'com.google.firebase:firebase-storage:16.0.1'

// Required only if Facebook login support is required
implementation 'com.facebook.android:facebook-android-sdk:4.34.0'

//Google sign-in with Firebase Authentication
implementation 'com.google.android.gms:play-services-auth:15.0.1'

The necessary facebook strings:

<string name="facebook_application_id" translatable="false">#######</string>
<string name="facebook_login_protocol_scheme" translatable="false">fb#######</string>

In my activity I have:

void signIn() {
    AuthUI.IdpConfig facebookIdpConfig = new AuthUI.IdpConfig.FacebookBuilder()
            .setPermissions(Arrays.asList("user_friends"))
            .build();
    List<AuthUI.IdpConfig> providers = Arrays.asList(
            new AuthUI.IdpConfig.EmailBuilder().build(),
            new AuthUI.IdpConfig.GoogleBuilder().build(),
            facebookIdpConfig);

    startActivityForResult(
            AuthUI.getInstance().createSignInIntentBuilder()
                    .setTheme(AuthUI.getDefaultTheme())
                    .setLogo(R.drawable.com_facebook_button_login_logo)
                    .setAvailableProviders(providers)
                    .build(),
            RC_SIGN_IN);
}

Before clicking Facebook sign in button: Sign in buttons

After clicking Facebook sign in button: Error page after clicking button

Error log after closing the Facebook error page:

I have searched other questions who have had problems similar to mine but their answers do not solve my problem.

Thank you in advance!

When you use this command

keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64

to get the Key Hashes you put in facebook configurations, it will ask you for a password, make sure you enter android as the password.

I don't think there's anything wrong with the configurations, it's working on higher Android APIs – Mr.O Oct 04 '18 at 09:36
It's imperative you use "android" as the password... I was trying to use some other personal password and it wouldn't work. Thanks, it's working for me. – Shane Sepac Feb 08 '19 at 00:14

Did you enable facebook sign In In firebase?

Check your app id and App secret key is the same as developer.facebook.com

In developer.facebook.com go to your app, And then Setting->Basic Check App Id and App Secret is same as facebook SignIn in firebase

Also, don't forget to add outh Url in your app in the Facebook developer page
