Android多个dex文件定义了Lcom/google/android/gms/common/api/zza

Question

在API级别为22或25的模拟器上构建项目并部署应用程序可以顺利进行，但是当我尝试在API级别为16的真实设备上构建APK或部署应用程序时，我会收到以下错误：

Error:Execution failed for task ':app:transformClassesWithDexForDebug'.
> com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.dex.DexException: Multiple dex files define Lcom/google/android/gms/common/api/zza;

我的项目build.gradle文件：

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.2.2'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
        classpath 'me.tatarka:gradle-retrolambda:3.3.0-beta4'
        classpath 'com.google.gms:google-services:3.0.0'
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

我的应用程序 build.gradle 文件：

apply plugin: 'com.android.application'
apply plugin: 'com.neenbedankt.android-apt'
apply plugin: 'me.tatarka.retrolambda'
apply plugin: 'com.google.gms.google-services'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.1"
    defaultConfig {
        applicationId "<aplication id here>"
        minSdkVersion 16
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        vectorDrawables.useSupportLibrary = true
    }

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

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

}

dependencies {

    final SUPPORT_LIBRARY_VERSION = '25.0.1'
    final DAGGER_VERSION = '2.4'
    final BUTTERKNIFE_VERSION = '8.0.1'
    final TIMBER_VERISON = '4.3.0'
    final LEAKCANARY_VERSION = '1.4'
    final FIREBASE_VERSION = '10.0.0'
    final FIREBASE_UI_VERSION = '1.0.0'

    compile fileTree(dir: 'libs', include: ['*.jar'])

    compile "com.android.support:appcompat-v7:$SUPPORT_LIBRARY_VERSION"
    compile "com.android.support:design:$SUPPORT_LIBRARY_VERSION"
    compile "com.android.support:recyclerview-v7:$SUPPORT_LIBRARY_VERSION"
    compile "com.android.support:cardview-v7:$SUPPORT_LIBRARY_VERSION"
    compile "com.android.support:support-v4:$SUPPORT_LIBRARY_VERSION"
    compile "com.android.support:support-vector-drawable:$SUPPORT_LIBRARY_VERSION"

    compile "com.google.dagger:dagger:$DAGGER_VERSION"
    apt "com.google.dagger:dagger-compiler:$DAGGER_VERSION"

    compile "com.google.firebase:firebase-database:$FIREBASE_VERSION"
    compile "com.firebaseui:firebase-ui-database:$FIREBASE_UI_VERSION"

    compile "com.jakewharton:butterknife:$BUTTERKNIFE_VERSION"
    apt "com.jakewharton:butterknife-compiler:$BUTTERKNIFE_VERSION"

    compile "com.jakewharton.timber:timber:$TIMBER_VERISON"

    debugCompile "com.squareup.leakcanary:leakcanary-android:$LEAKCANARY_VERSION"

    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })

    testCompile 'junit:junit:4.12'
}

注意: 如果我在defaultConfig中加入"multiDexEnabled true"这一行，我会得到以下错误：

Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.
> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: com/google/android/gms/common/api/zza.class

Answer 1

移动这个：

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

到您的app/build.gradle文件底部。

Answer 2

对我来说，我只是将 Firebase 库更新到最新版本，然后它就可以正常工作了。

Answer 3

这可能与原问题无关，但如果有助于其他人，我遇到了我的ionic v1项目的这个错误。我不使用firebase，但我通过this answer解决了它（对我来说很容易的修复方法-在android/project.properties中将所有google服务版本标准化为相同版本）

Answer 4

虽然我遇到了相同的错误，但上述解决方案对我无效。我通过将firebase-ui库版本从2.0.0降级到1.2.0并在项目级别的build.gradle文件中添加以下内容来解决该错误：

allprojects {
    repositories {
        jcenter()

        // Add the following
        maven {
            url 'https://maven.fabric.io/public'
        }
    }
}
