title: Read/write external storage on Android
body: <p>I'm developing an Android application that reads and writes data in a <code>/sdcard/MyFolder</code> directory. I get the sdcard path trough the method <code>Environment.getExternalStorageDirectory()</code>.</p>
  
  <p>I tested the application on a Samsung device where the path returned by the method is <code>/mnt/sdcard</code> on which I append <code>/MyFolder</code>; all works fine and I can r/w files in this folder. 
  Now I'm trying to do the same on a Nexus device: I have put my files to read in the <code>/sdcard/MyFolder</code> directory and <code>getExternalStorageDirectory()</code> returns <code>/storage/emulated/0/</code> as path, on which I append <code>/MyFolder</code>. But in this case I cannot find the files to read.</p>
  
  <p>I set all the storage permissions in the manifest.</p>
  
  <p>Am I doing something wrong? Is there any particular issue related to an emulated directory?</p>
  
  <p>Thanks</p>
