Android obtains audio, video, and image information

MediaStore provides audio, video, and image information, which can be read through ContentResolver.

First, we provide three classes: Audio, Video, and Image. Then we define three providers: AudioProvider,

VideoProvider, ImageProvider, looks like the factory method mode is used: D, finally, an example class Provider is provided.
