title: How to set the icon and title on Android TV home screen for the currently running task
body: <p>I have enabled picture-in-picture mode for an Android TV app based on this guide: <a href="https://developer.android.com/guide/topics/ui/picture-in-picture.html" rel="nofollow noreferrer">https://developer.android.com/guide/topics/ui/picture-in-picture.html</a></p>
  
  <p>When I enter PiP mode, and navigate to the home screen of the Android home screen, it shown at the top the currently running task (PiP window) with an icon an title and options to Open and Close.</p>

  <p>I could not find any documentation on how to set the the title and the icon (but most importantly the title). I have tried setting the <a href="https://developer.android.com/reference/android/app/ActivityManager.TaskDescription.html" rel="nofollow noreferrer">ActivityManager.TaskDescription</a> but without any luck. Also note that I <strong>do have an app title set in the Manifest</strong>, but that is not being shown here. Also note that in the task switcher, the app title and icon is shown correctly.</p>
  
  <p>Any ideas how to set the <code>(No title program)</code> from the screenshot?</p>
  
  <p>Tested on Android TV API 26, 27, as Picture-in-Picture is only available since Oreo.</p>
