title: Set Focus Mode programatically
body: <p>Is it possible to set <a href="https://www.blog.google/products/android/android-focus-mode" rel="nofollow noreferrer">focus mode</a> programatically in Android?
  I was hoping for a system API like the following, but don't see focus mode in the system APIs.</p>
  <p><code>Settings.System.putInt(getContentResolver(), Settings.System.FOCUS_MODE, 1);</code></p>
