标签: java android gradle android-gradle build.gradle

我收到此错误:

  

错误:任务执行失败   ':应用程序:transformClassesWithDexForDebug'

     
    

com.android.build.api.transform.TransformException:com.android.ide.common.process.ProcessException:     java.util.concurrent.ExecutionException:com.android.dex.DexException:     多个dex文件定义Lcom / google / android / gms / internal / zzeg;

  

运行应用程序时!

但我猜问题就在于gradle。我搜索了解决方案,我发现可能有不同版本的播放服务声明。但我没有发现任何错误!

请帮我解决问题。我是Firebase和依赖项的新手。

这是我的构建gradle(app):

// 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:2.3.3'
        classpath 'com.google.gms:google-services:3.1.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com" // Google's Maven repository
        }
    }
}

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

这是build.gradle(项目)文件:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.1"
    defaultConfig {
        applicationId "com.eaglewap.cleancity"
        minSdkVersion 17
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })

    // Displaying images
    compile 'com.github.bumptech.glide:glide:3.6.1'

    //Firebase
    compile 'com.google.firebase:firebase-database:11.2.2'
    compile 'com.google.firebase:firebase-storage:11.2.2'
    compile 'com.google.firebase:firebase-auth:11.2.2'
    compile 'com.google.firebase:firebase-messaging:11.2.2'
    compile 'com.google.firebase:firebase-config:11.2.2'
    //Firebase UI
    // Single target that includes all FirebaseUI libraries above
    compile 'com.firebaseui:firebase-ui:2.3.0'


    compile 'com.android.support:appcompat-v7:26.0.1'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    testCompile 'junit:junit:4.12'
}
apply plugin: 'com.google.gms.google-services'

1 个答案:

答案 0 :(得分:1)

这是因为当你使用:

// Single target that includes all FirebaseUI libraries above
compile 'com.firebaseui:firebase-ui:2.3.0'

与使用相同:

// FirebaseUI Database only
compile 'com.firebaseui:firebase-ui-database:2.3.0'

// FirebaseUI Auth only
compile 'com.firebaseui:firebase-ui-auth:2.3.0'

// FirebaseUI Storage only
compile 'com.firebaseui:firebase-ui-storage:2.3.0'

位于documentation,它表示需要Firebase / Play服务版本11.0.4。但是你使用11.2.2,所以firebase-ui库将包含它的传递依赖,它使用的是11.0.4。因此发生了冲突。

因此,您可以使用Firebase / Play服务版本11.0.4,也可以添加播放服务验证。

对于Auth,您需要包含播放服务版本:

compile "com.google.firebase:firebase-auth:11.2.2"
compile "com.google.android.gms:play-services-auth:11.2.2"
