title: How get path to secondary external directory for Camera files
body: <p>I have a device with an SD card. Now I want to check that device has mounted an external SD card and can read files from the public DCIM folder. I know that I can use <code>Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);</code>, but this method returns only files, that is on primary external memory, not on the mounted SD card (Secondary external storage). </p>
  
  <p>I found that <code>Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM);</code> returns an element with index 1, for the secondary external storage, but this method gets files only for application sandbox (Android/data/packagename). So my question is how get path to secondary external path for public directory like DCIM?</p>
