Hi Dave Sparks, According to above discussion raw aac file format not supported in the android.

[android-developers] Re: Audio streaming/progressive download over HTTP
I'm currently using the MediaPlayer class to play some files. However, it seems that whenever I seek back and forth, it needs to re-download and buffer parts it has already played. Is this what you mean by no progressive download yet? On Apr 14, 2:56 pm, Dave Sparks davidspa...@android.com wrote: We don't have an API for progressive download yet.

[android-developers] Re: Audio streaming/progressive download over HTTP
AAC inside an MP4 file is fine. There is no support for raw AAC streams.

Can we use rtsp streaming with a MPEG-4 video containing an AAC audio channel? On Apr 14, 11:56 pm, Dave Sparks davidspa...@android.com wrote: We don't have an API for progressive download yet.

MediaPlayer supports progressive download according to the developer guide from this linkhttp://developer.android.com/guide/topics/media/index.html (If you're passing a URL to an online media file, the file must be capable of progressive download.). As far as I understand progressive download means media playback during download process with saving the media file to file system(SD card or internal FS) after the downloading is finished (if it's a file, not a stream in the passed URL). So, I tried to set the following URL: setDataSource (http://84.204.154.49/mmapi/music.mp3). Playback is fine, but the file isn't saved to SD card or internal phone file system. Can MediaPlayer save media content to the file system after downloading is completed? Is there a way to turn on such capability? 2. Does MediaPlayer support HTTP streaming?
