android - 将 Http-4.2.1 包含在 Android 应用程序中

Question

我希望在我的 Android 应用程序中包含最新版本的 Http，即 4.2.1。现在希望从 Apache 网站下载该库并将其包含在 libs 文件夹中，然后包含在我的应用程序的构建路径中。

在包含 Http - 4.2.1 时，我在 logcat 中得到以下输出

我的问题是我可以这样做吗？这会与 SDK 中已包含的 Http 库版本产生冲突吗？

不幸的是这个问题没有一个优雅而干净的解决方案。您唯一的选择是使用 Maven Shade 插件或使用可用库的预打包分支 here 将所有 HttpClient 类移动到自定义命名空间 ('org.apache.http' -> 'my.http')

即日起也可以使用官方port of Apache HttpClient 4.3 to Google Android 。
