问题 If we wanted to make an HTTP/1.0 or HTTP/1.1 request, for example bytes 20000 to 100000 or seconds 20 through 35 seconds of a given media resource for example, .webm or .ogg audio or .mp4 video, where the response would be a discrete media fragment capable of playback without other portions of the media resource, how would we achieve this?

问题 My application shows the list of songs in sdcard, and there is an option to delete the song from SD card. Even when the song is deleted the song still comes in my applications list.
