Android Studio：将字节码转换为dex出错

问题描述：

当我尝试在手机上安装应用程序时出现错误。我试图清理该项目，然后再做，但不起作用。当我只重建项目时，它正在工作。这是错误我得到：Android Studio：将字节码转换为dex出错

，这是我的build.gradle（项目：项目名称）

// Top-level build file where you can add configuration options common to all sub-projects/modules. 

buildscript { 

    repositories { 
     google() 
     jcenter() 
     maven {url 'https://maven.fabric.io/public'} 
    } 
    dependencies {

当我必须更新谷歌播放服务时，它开始发生。但我不知道我应该改变什么。

答

检查指向同一个jar的重复库，类似于这个SO post中发生的情况。

您还可以从this post阅读：

你的问题，我认为是，无论你是联系图书馆您的主项目，你有两个用于您的支持库和注解之间的相同依赖关系。

如果您将库项目作为应用程序的依赖关系您只需要将依赖关系置于库依赖项关闭中。

问题是您有两个dex文件，因为有两个文件具有相同的名称，因为文件与依赖项重叠。

答

在我的情况下，Java和Kotlin中有两个类似的文件（例如“SomeView.java”和“SomeView.kt”）。
