title: How to simply open directory/folder?
body: <p>DONT mark this as duplicate, before reading what I need.</p>
  
  <p>I have seen many similar topics, but in none of them I've found solution.
  I need the simplest thing:  In my application I have button "View Media Files". After clicking that button, i need to be opened (with built-in File Explorer) this directory - <strong>SD_CARD/my_folder</strong> where are media files (and I want to click any of them and they should be opened in default Media player)..</p>
  
  <p>I have used all suggested answers on SO , like this:</p>
  
  <pre><code>    Intent intent = new Intent(Intent.ACTION_VIEW);
      Uri mydir = Uri.parse("/sdcard/Recorder_Videos");
      intent.setDataAndType(mydir, "*/*");
      startActivity(intent);
  </code></pre>
  
  <p>but all they do:   after clicking button, it opens "Choose File" menu:
  (Where I cant still play media files when clicking)</p>
