title: How to tell if screen is on with ADB
body: <p>I am looking to find out whether or not it is possible to determine if the screen is on on an android device using ADB. I need to know this for some tests I am trying to run using monkey runner. Is there a shell command I can enter, and thus include as part of a monkey runner command, that will tell me definitively if the screen is on or off?</p>
