title: How to detect if Daydream is on?
body: <p>Is it possible to detect if Daydream is on or off? If so, how?</p>
  
  <p>Edit: To clarify, I looking to read the system setting for DayDream (much like you can for airplane mode and other settings). You can infer that from Intent.ACTION_DREAMING_STARTED and Intent.ACTION_DREAMING_STOPPED, but it's not the same thing.</p>
