导入了2个第三方jar包：httpmime-4.3.5.jar、httpcore-4.3.2.jar包，打包时这2个包不混淆（-libraryjars libs/httpcore-4.3.2.jar， -libraryjars libs/httpmime-4.3.5.jar），包里面涉及到android系统org.apache.http包下面的相关类，所以混淆代码的时候报错如下：

最上面了个Note: there were 1059 duplicate class definitions，这个可以忽略。主要是下面的Warning，打包的时候可以直接在proguard-project.txt中加入
-ingorewarnings
这样确实是可以正常打包，但实际治标不治本，打包的apk不一定能正常工作。我自己在项目中，添加-ingorewarnings打包后，所有http请求都失败了。
正确的解决方法其实最下面几段提示已经写出来了：You must avoid such dependencies, since the program classes will be processed, while the library calsses will remain unchanged。意思是说：程序中的类被混淆后，jar包中的类还没有改变，导致了不一致。所以解决方法是，程序中的这些类也不混淆，添加如下代码：
-dontwarn org.apache.http.**
-keep class org.apache.http.** { *;}
需要说明的是，报错直接添加-ignorewarning其实是很不好的方式，注意查看console的提示信息。
