android获取音频、视频、图片信息


		MediaStore提供了音频、视频、图片信息，我们可以通过ContentResolver进行读取。
首先给出了Audio,Video和Image三个类，然后分别定义了三个Provider:AudioProvider,
VideoProvider,ImageProvider，貌似用到了工厂方法模式:D，最后给出了一个示例类Provider。

package com.provider;public class Audio {    
private int id;    
private String title;    
private String album;

private String mimeType;    
private long duration;    
private long size;
