开源小项目：xhuloo1.3.2

xhuloo作为学习ANDROID编程的DEMO，UI设计十分差（基本没有设计），但它可作为初学的演示，它简单十分，浅显易懂。没有实用价值，作为编程（API）的探究。

 

---

xhuloo1.3.2 release 增加新功能

1）android id —>XhulooActivity_PHONE

2) 自定义列表 —->XhulooActivity_weatherreport(发展为天气预报功能）

3）震动 —> XhulooActivity_MEM

 

 

 

---

发展方向：

1）完善文件游览功能,BACK功能

2）读取 设备的IP地址，等信息

3）SERVICE后台功能

4）天气预报
