在更新了我的google play服务和google存储库之后，我还更新了我的firebase sdk，当我开始运行应用程序时出现此错误，但是当我对它进行gradle时没有编译错误。

这是我得到的错误：

Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'. 

com.android.build.api.transform.TransformException：java.util.zip.ZipException：重复条目：com / google / android / gms / auth / api / signin / internal / zzf.class

这是我的gradle应用程序：

 apply plugin: 'com.android.application' android { compileSdkVersion 24 buildToolsVersion "24.0.2" defaultConfig { applicationId "com.myapp.maecea.ipon4" minSdkVersion 16 targetSdkVersion 24 versionCode 5 versionName "5.0" multiDexEnabled true } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } dependencies { compile fileTree(include: ['*.jar'], dir: 'libs') testCompile 'junit:junit:4.12' compile 'com.android.support:appcompat-v7:24.2.0' compile 'com.android.support:recyclerview-v7:24.2.0' compile 'com.google.firebase:firebase-database:10.0.1' compile 'com.google.firebase:firebase-auth:10.0.1' compile 'com.firebase:firebase-client-android:2.3.1' compile 'com.firebaseui:firebase-ui-database:0.4.0' compile 'com.firebaseui:firebase-ui:0.4.0' } apply plugin: 'com.google.gms.google-services' 

虽然这是我的gradle项目：

 // 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:2.1.3' classpath 'com.google.gms:google-services:3.0.0' // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } } allprojects { repositories { jcenter() mavenLocal() } } task clean(type: Delete) { delete rootProject.buildDir } 

这是我更新的依赖项：

  apply plugin: 'com.android.application' android { compileSdkVersion 24 buildToolsVersion "24.0.2" defaultConfig { applicationId "com.myapp.maecea.ipon4" minSdkVersion 16 targetSdkVersion 24 versionCode 5 versionName "5.0" multiDexEnabled true } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } dependencies { compile fileTree(include: ['*.jar'], dir: 'libs') testCompile 'junit:junit:4.12' compile 'com.android.support:appcompat-v7:24.2.0' compile 'com.android.support:recyclerview-v7:24.2.0' compile 'com.google.firebase:firebase-database:10.0.1' compile 'com.google.firebase:firebase-auth:10.0.1' compile 'com.firebaseui:firebase-ui-database:0.4.0' compile 'com.firebaseui:firebase-ui:0.4.0' } apply plugin: 'com.google.gms.google-services' 

Answer 1

要解决无法解决的次要问题：com.twitter.sdk.android:twitter:2.2.0 ，请更新您的顶级（Project）build.gradle文件以包含这些存储库：

  repositories { jcenter() mavenLocal() mavenCentral() maven { url 'https://maven.fabric.io/public' } } } 

这取自Firebase UI示例应用程序的项目构建文件 。

Answer 2

添加播放服务。

 compile 'com.google.android.gms:play-services-auth:10.2.1'
