title: is it possible to detect when any application is in full screen in android?
body: <p>I would like to know if there is some sort of way using maybe views or something to have a background service detect if the foreground app is in full screen or not. meaning the status bar is hidden or not hidden. </p>
  
  <p>I was thinking maybe using constant strings to detect if a view is shown or not? But im not sure exactly. Root is an option if needed. </p>
  
  <p>Thanks guys!!</p>
