title: Picasso download random image
body: <p>in my new app, at some point I need to fetch a random image (i use this <a href="http://unsplash.it/200/?random" rel="nofollow noreferrer">link</a>) using Picasso. The problem is even if I set the network policy to no cache the image stays the same if I exit the activity and relaunch it.
  Note it's the second activity that contains this Picasso downloading</p>
