Added in 1.1.0

Kotlin |Java

class NotificationCompat.CarExtender : NotificationCompat.Extender

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

Create an NotificationCompat.Builder, setting any desired properties.
Create a CarExtender.
Set car-specific properties using the add and set methods of CarExtender.
Call extend to apply the extensions to a notification.
Post the notification to the notification system with the NotificationManagerCompat.notify(...) methods and not the NotificationManager.notify(...) methods.

Notification notification = new NotificationCompat.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.
