title: Set default viewer for VrVideoView in Google VR SDK
body: <p>I am using Google VR SDK's VrVideoView control to play mono 360 videos in my app. When I click on the Cardboard icon to use with an unofficial Cardboard viewer, the default viewer is set to the Google's Cardboard viewer. If I wanted to change this to work with a specific unofficial one, I need to install the separate Google Cardboard app on Android.</p>
  
  <p>Is there a way to change the default viewer on VrVideoView without requiring the user of my app to download the separate Cardboard app? I have the URL to the viewer profile of the official Cardboard when registered from: <a href="https://vr.google.com/cardboard/viewerprofilegenerator/" rel="nofollow">https://vr.google.com/cardboard/viewerprofilegenerator/</a></p>
