title: What is the default color of the dialog background fill?
body: <p>When Android <code>AlertDialog</code> shows, the background around this dialog becomes darker. This is probably achieved by first filling the whole screen with a half-transparent color and then putting a dialog on top of that.</p>
  
  <p>My question is: what is the default color of that background fill?</p>
