title: Android open folder image with built-in gallery
body: <p>I want to open a images folder with android built-in gallery.
  For example, I have a folder path that contains images, i want to open it with gallery.
  I am using this code, it opens the gallery that contains no images.
  Any idea?</p>
  
  <pre><code>    Intent intent = new Intent();
      intent.setAction(Intent.ACTION_VIEW);
      intent.setDataAndType(Uri.fromFile(new  File(folderImages)),"image/*");
      startActivityForResult(intent, 1);
  </code></pre>
