TvExtender

Helper class to add Android TV extensions to notifications.

To create a notification with a TV extension:

1. Create an NotificationCompat.Builder, setting any desired properties.
2. Create a TvExtender.
3. Set TV-specific properties using the set methods of TvExtender.
4. Call extend to apply the extension to a notification.

Notification notification = new NotificationCompat.Builder(context)
        ...
        .extend(new TvExtender()
                .setChannelId("channel id"))
        .build();
NotificationManagerCompat.from(mContext).notify(0, notification);

TV extensions can be accessed on an existing notification by using the TvExtender(Notification) constructor, and then using the get methods to access values.

Note that prior to O this field has no effect.
