一份在android下学习GPS和运用百度地图api(Learning to use a GPS and Baidu map api in android)

本项目是一个简易的文件管理器，打开以后遍历可读的文件夹。内置文本编辑器，可以编辑文本文档，并且保存编辑后的文本信息。可以进行文件的操作有复制、粘贴、新建文件/文件夹、重命名、删除文件或文件夹等功能。但是目前只支持复制文本文件。点击文件以后可以获取文件的MIME类型并且列出所有可能打开该文件的程序选择器。如果是html文件则用本项目内置的网页浏览器工具打开，本项目注释很丰富。代码量不大，很方面学习和研究文件管理方面的内容。系统文件的管理需要root权限
