意外的顶级异常:com.android.dex.DexException:多个dex文件定义

当我将谷歌分析的配置添加到我的Android项目并构建项目时,我收到以下错误:

:app:transformClassesWithDexForDebug

这是什么意思,我该如何防止这个错误？

Answer 1

这里的游戏有点晚了,但这很可能是你在build.gradleapp文件中列出的依赖项的问题.

经过大量测试后,我成功地追查了我的问题并相信它可能对其他人有所帮助.

我不推荐的事情:

除非你绝对需要在你的build.gradle中启用multiDex,否则不要这样做,这只是踩过你应用中的底层问题而不是找到它的根源.您也不必要地增加了apk的大小,并且当您的dex文件中存在冲突方法时可能会发生意外崩溃.

需要注意的事项:

检查build.gradle文件中的所有依赖项.您是否引用了包含已包含的依赖项的依赖项？例如,如果您包含appcompat-v7,则不需要包含appcompat-v4,因为v7包含v4中的所有功能.

我实际上发现了什么(我的问题导致我的应用超出我的dex文件中的方法限制)----> GOOGLE PLAY SERVICES

如果你并不需要所有的谷歌Play服务库依赖AWAY STAY从这一行你的build.gradle compile 'com.google.android.gms:play-services:8.3.0',而是只使用你所需要的!

Google有一个完整的库列表,可以在这里有选择地进行编译

尽管如此,您可能只需要在Gradle中为Google Analytics包含这一行:

  dependencies{
       compile 'com.google.android.gms:play-services-analytics:8.3.0'
  }

编辑

此外,您可以通过转到项目的根目录(或在Android工作室中使用终端)并运行来查看依赖关系树:

./gradlew app:dependencies

祝你好运,编码愉快!

更新

从Android Studio 2.2开始,无论您是否需要在应用程序中使用multi-dex,都不再需要反复试验.使用Apk Analyzer查看它是否真的需要!

Answer 2

说明: 使用超过65K方法构建应用程序

Android应用程序(APK)文件包含Dalvik可执行文件(DEX)文件形式的可执行字节码文件,其中包含用于运行应用程序的编译代码.Dalvik可执行规范将单个DEX文件中可引用的方法总数限制为65,536,包括Android框架方法,库方法和您自己的代码中的方法.超过此限制要求您配置应用程序构建过程以生成多个DEX文件,称为多索引配置.

注意: 这允许您引用应用程序的所有方法.就好像你有两个模块(限制:2 x 65K)但是压缩成一个模块.这需要构建过程中的成本(时间).

解:

1. 您应该尝试使用库格式化代码以删除多余的类,也不要超过限制方法.例如,如果您使用地图播放服务(com.google.android.gms:play-services:8.1.0),则可以更改为(编译'com.google.android.gms:play-services-maps:8.1. 0')消除不必要的库依赖.然后在AndroidStudio中同步Gradle并检查它是否运行.如果没有运行转到第2点.
2. 在build.gradle(app模块)上添加它.

android {
   ...
   defaultConfig {
      ...
      multiDexEnabled true
   }
}

Answer 3

对我而言,它与simplexml转换器有关,用于改造2.它由以下固定:

compile ("com.squareup.retrofit2:converter-simplexml:2.0.0-beta4"){ exclude module: 'stax' exclude module: 'stax-api' exclude module: 'xpp3'}
