title: Square Picasso not displaying images from disc cache
body: <p>Downloading images and caching in memory is working. 
  But there are no displayed image when I turn off internet connection. I expect that there should be displayed images from disc cache. I have checked that images are downloaded to /data/data//cache/picasso-cache</p>
  
  <p>When I debugging there is exeception in
  BitmapHunter, method run():</p>
  
  <p><i>java.net.ConnectException: failed to connect to /192.168.1.111 (port 8080) after 15000ms: connect failed: ENETUNREACH (Network is unreachable)</i></p>
  
  <p>I did not setup disc caching in my project in any way, I have only added new maven dependency "okhttp" except picasso</p>
