title: how to set MEDIASTORE to get image from specific folder on android
body: <p>So i have this code for getting images with mediastore :</p>
  
  <pre><code>int dataIndex = mMediaStoreCursor.getColumnIndex(MediaStore.Files.FileColumns.DATA );
  
  mMediaStoreCursor.moveToPosition(position);
  String dataString = mMediaStoreCursor.getString(dataIndex);
  Uri mediaUri = Uri.parse("file://" + dataString);
  return mediaUri;
  </code></pre>
  
  <p>This good gets all the images in the pictures folder, i would like to change that to get all the images in a specific folder, which will be passed in as a string. e.g <code>{ android/picture/specificfolder/}</code></p>
