WearableExtender

class WearableExtender : Notification.Extender
kotlin.Any
   ↳ android.app.Notification.WearableExtender

Helper class to add wearable extensions to notifications.

See Creating Notifications for Android Wear for more information on how to use this class.

To create a notification with wearable extensions:

  1. Create a android.app.Notification.Builder, setting any desired properties.
  2. Create a android.app.Notification.WearableExtender.
  3. Set wearable-specific properties using the add and set methods of android.app.Notification.WearableExtender.
  4. Call android.app.Notification.Builder#extend to apply the extensions to a notification.
  5. Post the notification to the notification system with the NotificationManager.notify(...) methods. 
Notification notif = new Notification.Builder(mContext)
          .setContentTitle("New mail from " + sender.toString())
          .setContentText(subject)
          .setSmallIcon(R.drawable.new_mail)
          .extend(new Notification.WearableExtender()
                  .setContentIcon(R.drawable.new_mail))
          .build();
  NotificationManager notificationManger =
          (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
  notificationManger.notify(0, notif);

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

Notification.WearableExtender wearableExtender = new Notification.WearableExtender(
          notification);
  List<Notification> pages = wearableExtender.getPages();
