Firebase API 初始化失败 Android+Firebase

Question

任何人请帮助我我是 android 开发的新手，请帮助我..

我添加了一个 firebase recyclerview 和 firebaseui 之后我收到这个错误我不知道该怎么做

在我模块的 gradle 文件中，我添加了：

 compile 'com.google.firebase:firebase-auth:11.6.0' and 

'com.google.firebase:firebase-database:11.6.0'

下面提供了完整的 Gradle 文件：

Top level gradle file

buildscript {

repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.1.3'

    classpath 'com.google.gms:google-services:3.1.1'
}
}

allprojects {

repositories {
    google()
    jcenter()
    maven()
            {
                url "https://google.com"
            }
   }
}

task clean(type: Delete) {

     delete rootProject.buildDir
 }

Module Gradle file

apply plugin: 'com.android.application'

android {
  compileSdkVersion 28
  defaultConfig {
    applicationId "com.pachu.my_notification"
    minSdkVersion 21
    targetSdkVersion 28
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

dependencies {
  implementation fileTree(include: ['*.jar'], dir: 'libs')
  //noinspection GradleCompatible
  implementation 'com.android.support:appcompat-v7:28.0.0'
  implementation 'com.android.support.constraint:constraint-layout:1.1.3'
 implementation 'com.google.firebase:firebase-auth:11.6.0'
  implementation 'com.google.firebase:firebase-database:11.6.0'
  testImplementation 'junit:junit:4.12'
  androidTestImplementation 'com.android.support.test:runner:1.0.2'
  androidTestImplementation 'com.android.support.test.espresso:espresso- 
  core:3.0.2'
  implementation 'com.firebaseui:firebase-ui-database:4.2.1'
  implementation 'com.android.support:recyclerview-v7:28.0.0'
}

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

根据 FirebaseUI docs:

自版本 4.2.1 起，FirebaseUI 具有以下依赖版本：

 Library          Version
 firebase-auth      16.0.5
 play-services-auth 16.0.1
 firebase-database  16.0.3
 firebase-firestore 17.1.1
 firebase-storage   16.0.3

因此您需要将 firebase-database 更新到版本 16.0.3 并将 firebase-auth 更新到版本 16.0.5.

同时将 google 服务插件更新到 4.2.0
