CarExtender

class CarExtender : Notification.Extender
kotlin.Any
   ↳ 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 CarExtender.
  3. Set car-specific properties using the add and set methods of CarExtender.
  4. Call Notification.Builder.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.
