title: How do you make a resizable rectangle for cropping images in android?
body: <p>I want to crop my image which is being displayed on an <code>ImageView</code>. How I want to go about it is that I want a re-sizable rectangle to be displayed on the image. That rectangle will have moveable corners (which I can drag around with touch) to increase/decrease its size.
  The image below illustrates a demo of something I would like to develop.</p>
