android 隐藏自己的多媒体文件

Hiding your files from the Media Scanner

Include an empty file named .nomedia in your external files directory (note the dotprefix in the filename). This will prevent Android's media scanner from reading your mediafiles and including them in apps like Gallery or Music.

---------------------------------------

如果不想让系统的媒体扫描器扫描到自己应用的媒体文件时，就在应用的媒体文件中创建一个空的.nomedia文件，这将能避免应用中的媒体文件被系统的媒体扫描器扫描到，也包括像图库或音乐播放器之类的app。
