I changed the httpclient-4.0-beta1.jar and httpcore-4.0-alpha6.jar to httpclient-4.0.jar and httpcore-4.0.1.jar respectively and I no longer get the above exception [ java.lang.NoSuchMethodError ]This stackoverflow question helped me in solving this : java.lang.NoSuchMethodError: org.apache.http.protocol.BasicHttpContext: method <init>()V not found
我将 httpclient-4.0-beta1.jar 和 httpcore-4.0-alpha6.jar 分别更改为 httpclient-4.0.jar 和 httpcore-4.0.1.jar 并且不再出现上述异常[ java.lang.NoSuchMethodError ]这个 stackoverflow 问题帮助我解决了这个问题：java.lang.NoSuchMethodError: org.apache.http.protocol.BasicHttpContext: method <init>()V not found
But Now I get UnknownhostException on execution of any methods of the API
但是现在我在执行 API 的任何方法时得到 UnknownhostException

Your class should NOT be in package com.dropbox.client. Try moving it to a different (i.e. com.yourname.client). It looks like you might be creating a name clash and inadvertently overriding something in the Dropbox client API.
您的课程不应在 package 中com.dropbox.client。尝试将其移动到不同的（即com.yourname.client）。看起来您可能正在创建名称冲突并无意中覆盖了 Dropbox 客户端 API 中的某些内容。

You have specified api.getdropbox.com:80as the host name. Try using api.getdropbox.cominstead.
您已指定api.getdropbox.com:80为主机名。尝试使用api.getdropbox.com。
