意外的顶级例外：多个DEX文件中定义 [英] UNEXPECTED TOP-LEVEL EXCEPTION: Multiple dex files define

问题描述

我增加了第三lib添加到我的Andr​​oid项目。当我被蚂蚁收拾它，会出现一些错误：

I've added a third lib to my android project. And when I pack it by ant, some errors occur:

 [dx] UNEXPECTED TOP-LEVEL EXCEPTION:

推荐答案

这可以由双方你的应用程序项目和库项目使Android的支持-V4罐引起的。如果库项目已经把这个罐子的依赖，那么你需要从你的应用程序项目的classpath中排除。

This can be caused by both your app project and the library project bringing the android-support-v4 jar. If the library project is already bringing this jar as dependency then you'll need to exclude it from your app project classpath.
