You can use Retrovision with a Chromecast on Android by using Chrome for Android.  You can get that from the Google Play Store.  It won’t play the links from Hulu or Crackle.  Using the Beta versions of Chrome and Chromecast for Android might be an advantage.

On Windows, Linux and Mac PC’s, if you are using Chrome, you will get a menu to control a Chromecast with the following icons.

AND THE VOLUME CONTROL IS BACKWARDS

     Connect to browser add-on

     Load the Current Video and Play it

     Play/Resume

     Stop the Video,  don’t disconnect

     Disconnect the Chromecast

Connect and Load should get you there.  You need the Chrome add-on and, of course, a Chromecast to make this work.
