Note the application linked reduce the size of the image by cropping it.

If you want to reduce the stored bytes of an image you need to compress it using a lower quality. Here you trade quality for size.

Here is some code.

Bitmap bm = ... /* load your image into a bitmap object */

try {
  OutputStream out = new FileOutputStream(new File("my-smaller-image.jpg") ;
  bm.compress(Bitmap.CompressFormat.JPEG, 80 /* this is the quality parameter */, out) ;
  out.flush() ;
  out.close() ;
}
catch (Exception e) {}

Here the quality parameter is set to 80, use one of your choosing or giving you the correct file size.
