好久没更新了，最近都在做工具类的测试，这个是最新通过的，大家可以看看，发车喽
- 设备相关→DeviceUtils.java
isRoot : 判断设备是否root
getSDKVersion : 获取设备系统版本号
getAndroidID : 获取设备AndroidID
getMacAddress : 获取设备MAC地址
getManufacturer : 获取设备厂商，如Xiaomi
getModel : 获取设备型号，如MI2SC
shutdown : 关机
reboot : 重启

如果该工具类依赖其他工具类，都可以在我的Android开发人员不得不收集的代码(持续更新中)中找到。
