title: Android file copy
body: <p>I am finding that reading one line at a time from a text file on the SD card is rather slow. I imagine that it might be quicker if the file is in internal memory, so I want to copy files from the SD card to internal storage.</p>
  
  <p>The file copy examples I can find on the web seem to involve copying one byte at a time from an InputStream to an OutputStream or from a FileReader to a FileWriter. Is this really the quickest and most efficient method?</p>
