我想在我的應用程序中添加FirebaseUI身份驗證，但我很困擾它。我在我的應用中添加了Facebook，Twitter和電話號碼驗證，但它給了我錯誤：Cannot resolve method setAvailableProviders和Cannot resolve symbol IdpConfig。我應該怎樣做才能解決這個錯誤？你可以在圖像中看到我有錯誤和紅線。無法解析方法setAvailableProviders和無法解析符號IdpConfig
這裏是我的manifest.xml：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.anonymous.userlogin">
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-permission android:name="android.permission.INTERNET"/>
</manifest>
這裏是我的gradle這個文件
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.3.3'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
classpath 'com.google.gms:google-services:3.0.0'
}
}
allprojects {
repositories {
jcenter()
maven { url 'https://maven.fabric.io/public' }
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
這裏是我的gradle這個文件：

這裏是我的主要的代碼活動
package com.example.anonymous.userlogin;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import com.firebase.ui.auth.AuthUI;
import com.google.firebase.auth.FirebaseAuth;
import java.util.Arrays;
public class MainActivity extends AppCompatActivity {
private static final int RC_SIGN_IN = 123;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FirebaseAuth auth = FirebaseAuth.getInstance();
if (auth.getCurrentUser() != null)
{}
else
{
// not signed in
startActivityForResult(
AuthUI.getInstance()
.createSignInIntentBuilder()
.setAvailableProviders(
Arrays.asList(new AuthUI.IdpConfig.Builder(AuthUI.EMAIL_PROVIDER).build(),
new AuthUI.IdpConfig.Builder(AuthUI.PHONE_VERIFICATION_PROVIDER).build(),
new AuthUI.IdpConfig.Builder(AuthUI.GOOGLE_PROVIDER).build(),
new AuthUI.IdpConfig.Builder(AuthUI.FACEBOOK_PROVIDER).build(),

.build(),

}
}
}
