Question

我正在尝试在我的应用中添加FirebaseUI身份验证，但我很难坚持使用它。我在我的应用中添加了脸书，推特和电话号码验证，但它给了我错误：Cannot resolve method setAvailableProviders和Cannot resolve symbol IdpConfig。我应该怎么做我的应用程序来克服这个错误？你可以在图像中看到我有错误和红线。

这是我的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>

这是我的gradle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
}

这是我的gradle文件：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.2"
    defaultConfig {
        applicationId "com.example.anonymous.userlogin"

    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    //compile 'com.android.support:appcompat-v7:26.+'

    testCompile 'junit:junit:4.12'
}


apply plugin: 'com.google.gms.google-services'

configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == 'com.android.support') {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion '26.0.0-alpha1'
            }
        }
    }
}

这是我的主要活动的代码

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(),
                                                new AuthUI.IdpConfig.Builder(AuthUI.TWITTER_PROVIDER).build()))
                                .build(),
                        RC_SIGN_IN);




           }
    }
}

这是标记错误的屏幕截图：

Answer 1

您正在使用版本0.6.0的FirebaseUI Auth（com.firebaseui:firebase-ui-auth），它没有此功能。您应该使用版本2.x或3.x。

在您应用的build.gradle文件中更改此内容：

compile 'com.firebaseui:firebase-ui-auth:0.6.0'
//compile 'com.firebaseui:firebase-ui-auth:3.0.0'

对此：

compile 'com.firebaseui:firebase-ui-auth:3.0.0'

Answer 2

从此更改依赖性版本：

compile 'com.firebaseui:firebase-ui-auth:0.6.0'

对此：

implementation 'com.firebaseui:firebase-ui-auth:3.3.1'

并同步您的项目

无法解析方法setAvailableProviders并且无法解析符号IdpConfig
