我编写了一个 Android 应用程序，它使用来自 Apache 的 HttpComponents 来建立与服务器的连接。

我使用的版本是4.3（最新），一切正常，除了运行时。

我有异常

我添加到 libs 文件夹的库（在 jar 存档中）已导出，似乎应用程序使用内部 org.apache.http 包而不是我自己的库。

IDE 是 Intellij Idea。

有没有人解决这个问题之前请帮助我？

这个问题在 SO 中出现过几次。我采用的解决方案是使用名为httpclientandroidlib的库的重新打包版本。这在如何使用添加的 jar 中可用的类覆盖 Android Api 类的此问题的较新版本中作为解决方案提出？

您可以通过下一种方式使用自己的库 

com.yourlibrary.MyClass myClass= new com.yourlibrary.MyClass();
