每当我想运行我的项目时，我都会收到以下错误

错误：任务执行失败 ':app: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 landroid/support/design/widget/CoordinatorLayout$1;

请帮助我。我被这个问题困扰了几天。

Answer 1

我遇到了完全相同的问题。我通过将每个 Google 支持库更新到最新版本（在编写此解决方案时为 27.1.0）来解决此问题。我还将compileSdkVersion 更新到版本27，将buildToolsVersion 更新到版本27.0.3。我希望这能解决你的问题。

Answer 2

只需添加 multidex true 并为其添加一个依赖项。 校验码：

defaultConfig {
    ...
    multiDexEnabled true
}

添加依赖：

dependencies {
 compile 'com.android.support:multidex:1.0.1'
}

如果您想详细了解 multidex，请访问以下链接： https://developer.android.com/studio/build/multidex.html

快乐编码...

Answer 3

我的问题与使用同一库的不同版本有关。我的一个子依赖项引用了不同版本的 com.android.support:design，所以我在 build.gradle 中强制使用了

configurations.all {
    resolutionStrategy {
        force 'com.android.support:support-v4:27.1.0'
        force 'com.android.support:design:27.1.0'
    }
}

Answer 4

您应该在 build.gradle 文件中启用 multidex 属性

android {

    compileSdkVersion ..
    buildToolsVersion '...'

    defaultConfig {
       ...
       targetSdkVersion ..
       multiDexEnabled true  // this line will solve this problem
   }
}

Answer 5

试试这个...

apply plugin: 'com.android.application'

android {
compileSdkVersion 27
buildToolsVersion "27.0.2"
defaultConfig {
    applicationId "com.example.invinciblesourav.flacom"
    minSdkVersion 18
    targetSdkVersion 27
    versionCode 1
    versionName "1.0"

    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
sourceSets { main { assets.srcDirs = ['src/main/assets', 'src/main/assets/'] } }
}

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'
})

compile ('com.android.support:appcompat-v7:27.+')
compile 'com.android.support.constraint:constraint-layout:1.0.2'
compile 'com.google.firebase:firebase-auth:11.0.4'
compile 'de.hdodenhof:circleimageview:2.1.0'
compile 'com.theartofdev.edmodo:android-image-cropper:2.3.+'
compile 'com.google.firebase:firebase-core:11.0.4'
compile 'com.google.firebase:firebase-database:11.0.2'
compile 'com.google.firebase:firebase-storage:11.0.4'
compile 'com.android.support:design:25.3.1'
compile 'com.squareup.picasso:picasso:2.4.0'
testCompile 'junit:junit:4.12'
