Question

构建项目并将应用程序部署到具有API级别22或25的模拟器可以，但是当我尝试构建APK或将应用程序部署到具有API级别16的真实设备时，我收到以下错误：

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 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：如果我将“multiDexEnabled true”行添加到我的 defaultConfig ，我将收到以下错误：

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

移动它：

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

您的app / build.gradle文件的

to the bottom。

Answer 2

虽然我有同样的错误，但上述解决方案对我不起作用。我设法通过将我的firebase-ui库版本从2.0.0降级到1.2.0来解决错误，并将以下内容添加到Project level build.gradle文件中：

allprojects {
    repositories {
        jcenter()

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

Answer 3

对我来说，我只是将firebase库更新到最新版本，它只是工作

Answer 4

这可能不适用于原始问题，但万一它可以帮助其他人。我的离子v1项目遇到了这个错误。我没有使用firebase，但我确实用this answer修复了它（对我来说很容易修复 - 将所有google服务版本标准化为android / project.properties中相同）

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