title: android app installed on chrome os sd card path
body: <p>chromeos now allows android apps to access the SD card <a href="https://bugs.chromium.org/p/chromium/issues/detail?id=660189" rel="nofollow noreferrer">- link to ticket</a>.  So what is the path that the android app should use for the SD card?</p>
  
  <p>I am working on an android cordova app and using the <a href="https://github.com/apache/cordova-plugin-file" rel="nofollow noreferrer">"file" plugin</a> and I need a read only path to the SD card.  The file plugins "externalRootDirectory" is not correct, so what path should I use for a file:///path/to/sd-card?</p>
