title: Transparent notification bar with live wallpaper on Galaxy S4
body: <p><strong>Full Edit since it apparently wasn't clear that this is indeed a programming question</strong></p>
  
  <p>On the Galaxy S4, the notification bar is transparent by default. When using the built-in "Bubbles" wallpaper this looks as follows for example:</p>
  
  <p><img src="https://i.stack.imgur.com/OKmN9.png" alt="notification bar with bubbles wallpaper"></p>
  
  <p>Now I have developed my own live wallpaper. For sake of simplicity, I just fill the available canvas with <code>0xFFFF0000</code> for the screenshots, but normally it shows a different scene. On the Galaxy S4, my wallpaper does not show a transparent notification bar, but the default black one:</p>

  <p>I noticed that sometimes my wallpaper shows a transparent bar also, here on the lockscreen. However, I was unable to reliably reproduce the behaviour.</p>

  <p>My question is simply: is there any way to reliably enable the transparent notification bar from my wallpaper code or manifest? Actually, the unpredictable switching between transparent and black bar makes the user experience much worse than just with an always-black bar.</p>
