Notification.CarExtender

public static final class Notification.CarExtender
extends Object implements Notification.Extender

java.lang.Object
   ↳ android.app.Notification.CarExtender

Helper class to add Android Auto extensions to notifications. To create a notification with car extensions:

  1. Create an Notification.Builder, setting any desired properties.
  2. Create a Notification.CarExtender.
  3. Set car-specific properties using the add and set methods of Notification.CarExtender.
  4. Call extend(Notification.Extender) to apply the extensions to a notification. 
 Notification notification = new Notification.Builder(context)
         ...
         .extend(new CarExtender()
                 .set*(...))
         .build();

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