Question

我最近在我的应用程序中添加了MultiDex，并且我开始体验日志构建时间，所以我按照android网站上关于multidex的指南进行了操作，并添加了minSDK = 21的prod风格。

切换到devDebug构建版本并尝试运行应用程序后，我得到：

编辑：

使用minSDK 16添加风味（与defaultConfig中使用的相同）或
切换到上一次提交两者都使应用程序再次运行，没有这个问题。

Answer 1

仅当您 targetSdkVersion see documentation时才需要以下内容。

public class MyApplication extends MultiDexApplication

即修复它：

public class MyApplication extends Application

使用minSDK 21构建变量为路径上的类提供ClassNotFoundException：DexPathList
