title: Getting access to media player cache
body: <p>I want to move a progressively streamed mp3 file to sd card once it is completely loaded. Is there any way of achieving that. </p>
  
  <p>I've seen that the <code>MediaPlayer</code> completely downloads the whole file while progressive streaming and then we can seek to any part of file. I want to move a fully streamed file to external storage so that future playback do not waste data and battery.</p>
