title: Toggle "scanning always available" programmatically
body: <p>Starting with Android 4.3, there is an option under WiFi advanced settings page for "scanning always available". This ultimately means that WiFi is always on even if the user thinks they have disabled it (see this <a href="https://stackoverflow.com/questions/22860890/how-does-androids-scan-only-mode-work">link</a>).</p>
  
  <p>Is there a way to toggle this setting programmatically?</p>
