Thanks for any help.

推荐答案

谷歌Android附带了一个非常过时的（pre BETA 4.0）的Apache的HttpClient叉。由于老班的类路径的presence股票版本的HttpClient无法正确初始化，除非所有的类都移到另外一个名字空间（'org.apache.http' - >'thank.you.google.http）

Google Android ships with an extremely outdated (pre BETA 4.0) fork of Apache HttpClient. Due to the presence of old classes on the classpath the stock version of HttpClient fails to initialize correctly unless all classes are moved to another namespace ('org.apache.http' -> 'thank.you.google.http')

确保股票版本的Apache的HttpClient无法与原来的命名空间重叠的一种方法是用的，使用端口通过德克柏叶开发，或的的官方移植。

One way of making sure the stock version of Apache HttpClient does not overlap with its original namespace is repackaging it with the Maven Shade plugin, use the port developed by Dirk Boye, or the official port of Apache HttpClient to Google Android.
