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

Question

我正在使用电子邮件、Facebook 和谷歌提供商使用 Firebase-UI 身份验证。电子邮件和 Google 登录工作正常，但 Facebook 登录不工作。

我的 facebook 和 firebase 依赖项:

//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'

必要的 facebook 字符串:

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

在我的 Activity 中我有:

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);
}

在点击 Facebook 登录按钮之前: Sign in buttons

点击 Facebook 登录按钮后: Error page after clicking button

关闭 Facebook 错误页面后的错误日志:

我已经搜索了其他问题，他们遇到了与我类似的问题，但他们的答案并没有解决我的问题。

提前致谢!

当你使用这个命令时

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

要获取您在 facebook 配置中输入的 key 哈希，它会要求您输入密码，确保您输入 android 作为密码。
