PreviewChannel

public class PreviewChannel

Since API 26, all TV apps may create preview channels and publish them to the home screen. We call these App Channels (as distinct from the Live Channels row on the home screen). To help you create App Channels, the support library provides a number of classes prefixed by the word Preview-. This is a convenience class for mapping your app's content into a TvProvider Channel for publication. Use the provided Builder for creating your preview channel object. Once you create a preview channel, you can use PreviewChannelHelper to publish it and add programs to it.
