我們獲取的IP分區域網與外網，本篇帶來的就是外面ip的獲取方式

注意：許可權新增 （最好以下許可權都進行配置）

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS"/>
    <uses-permission android:name="android.permission.INTERNET"/>
 

Gson 依賴注入：

compile 'com.google.code.gson:gson:2.6.2'
