title: Change Android status bar color on home/lock screen based on custom events within an app
body: <p>I am currently developing a simple android app which should change the status bar color for home/lock screen based on certain events happening into the background(similar with how the status bar color turns orange when battery level drops under 10%). I know that status bar color can be changed within the application itself but can this be done at the system level without root access? </p>
  
  <p>Many thanks,
  Lucian</p>
