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，我得到了这个我不知道该怎么办的错误

在模块的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'

以下提供了完整的Gradle文件：

顶级gradle文件

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
 }

模块化Gradle文件

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：

从4.2.1版开始，FirebaseUI具有以下依赖项版本：

 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更新为版本16.0.3，并将firebase-auth更新为版本16.0.5。

还将Google服务插件更新为版本4.2.0

Firebase API初始化失败，Android + Firebase
