title: Copying files to system directory from app?
body: <p>For the purposes of this, say I had an Image on my SDcard. I'm looking for a way to copy this to the System/App directory, but cannot for the life of me figure out how to reference the directory. I have got SU permissions from the app, so that isn't the problem. Does anyone know how this can be done? Or how I can reference the system directory?</p>
  
  <p>Also I heard somewhere that I have to mount the System for read and write? How would I safely go about doing this?</p>
  
  <p>I've tried some InputStream and OutputStream IO using "\\system\\app\\file.png" or "system/app/file.png", but non seem to work.</p>
  
  <p>Thanks in advance</p>
