How can I get a random image on my lockscreen?
Everytime the user turns on the Kindle Fire, the lockscreen of the device presents a different background. (Of course it cycles trough a list of pictures and later it repeats itself) I'd like to achieve this behaviour on my phone. I'm not interested in the way of the unlock. I just want that custom pictures appear in the background of the lockscreen if I turn on the screen.
