试图监控一个app所有的网络通信。

前提 ：

1. 手机root过
2. 已成功安装xposed框架

XposedInstaller：

https://github.com/rovo89/XposedInstaller

操作步骤

1. 添加xposed框架XposedBridgeApi-54.jar包到android项目build path

2. assets目录下添加xposed_init文件内容为com.example.xposeddiy.Test，指示入口

3. AndroidManifest.xml文件application标签下添加

   [[meta-data
   android:name="xposedmodule"
   android:value="true" />
   [[meta-data
   android:name="xposedminversion"
   android:value="40" />
   [[meta-data
   android:name="xposeddescription"
   android:value="network monitor" />

4. hook android所有通信调用函数，代码如下
