断断续续用了几个星期写了这个mp3播放器，基本实现的功能有：播放mp3；自动到百度查找歌词；在相同目录查找封面

实现方式是扫描/sdcard目录下的mp3文件，加入到数据库中，包括id,path,cover,lyric,name字段。查看详情时更新cover和lyric，如果不合适删除封面和歌词以后就不会再查找。

有时候会出现莫名奇妙的错误，像播放时突然跳到歌曲的结尾，然后歌曲的当前播放位置一直增长。-Spent a few weeks off to write this mp3 player, basically features are: Play mp3　automatically to the Baidu search lyrics　in the same directory to find a scan of the cover implementations/sdcard directory mp3 files, added to the database, including the id, path, cover, lyric, name field. View the details of updated cover and lyric, remove the cover and the lyrics if inappropriate will no longer look after. Sometimes the error will appear baffling, such as playing music when suddenly jump to the end, and then the song currently playing position has been increased.
