我用的android studio，添加HttpClient的依赖包之后没有报错，但是编译不通过
首先声明，我使用的是android studio ，SDK用的是最近的23版本。
1、因为4.0之后已经没有了HttpClient，我添加了compile 'org.apache.httpcomponents:httpclient-android:4.3.5.1'依赖，但是还是找不到HttpClient的包！！这一步有错么？
2、然后我又百度加上自己不断换包五六次尝试，添加如下依赖compile 'org.apache.httpcomponents:httpclient-osgi:4.5.1'这个包，能够使用HttpClient了。但是令人崩溃的是居然HttpResponse又用不了，不知道是哪个包的问题。于是又百度加上换各种包尝试了四五次，发现添加compile 'org.apache.httpcomponents:httpcore:4.4.4'这个依赖之后，HttpRespone惊喜的可以用了。这个包导得有没有问题？
3、于是噼里啪啦打完代码，一运行，结果编译不过去，提示如下：

然后我彻底崩溃了！
我也知道这个错误的意思是这个包与androidSDK的内部版本冲突，但是你的内部版本不能用啊，我把compile 'org.apache.httpcomponents:httpclient-osgi:4.5.1'依赖删除之后立马报错，各种找不到类找不到方法。
我无数次实验，只有
compile 'org.apache.httpcomponents:httpclient-android:4.3.5.1'
compile 'org.apache.httpcomponents:httpcore:4.4.4'
compile 'org.apache.httpcomponents:httpclient-osgi:4.5.1'三个依赖全导才不报错
下图里面所有的apache的httpClient的依赖我通通导了个遍，并且所有排列组合都尝试过，两两搭配三三搭配，单独一个包。最后无解！
我自认为我真是拼了老命想靠自己来解决问题，但是喷了屏幕一口血，也没办法！希望大神帮帮我！
哈哈，那是因为你没试过这个包。这个包加上去本人亲测可以找到HttpClient
