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 网站下载库并将其包含在 libs 文件夹中，然后包含到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？这会与已经包含的 Http 库版本以及 SDK 产生一些冲突吗？

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 插件或使用此处提供的库的预打包分支将所有 HttpClient 类移动到自定义命名空间（'org.apache.http' -> 'my.http'）

到今天为止，还可以使用Apache HttpClient 4.3 的官方端口到 Google Android。

<classpathentry kind="con" path="com.android.ide.eclipse.adt.ANDROID_FRAMEWORK">
<accessrules>
<accessrule kind="nonaccessible" pattern="org/apache/http/**"/>
</accessrules>
</classpathentry>

我修复它像这样修改应用程序的 .classpath 文件，我在开源项目 open-gpstracker 中找到了解决方案
