I\'m using universal image loader and I get quite large numbers of images failing to load for users every day. I\'m using this code to get my errors to analytics.
I have never used Universal Image Loader but in the last few weeks a couple of really good alternatives have been released, they might be worth a look.
The first is Volley, Google's new networking lib announced at I/O 2013 https://developers.google.com/events/io/sessions/325304728
The second is Square's Picasso. The Square team do some really great work with their Android libs. http://corner.squareup.com/2013/05/picasso-one-dot-oh.html
