NotificationCompat.WearableExtender

public static final class NotificationCompat.WearableExtender
extends Object implements NotificationCompat.Extender

java.lang.Object
   ↳ androidx.core.app.NotificationCompat.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 NotificationCompat.Builder, setting any desired properties.
  2. Create a NotificationCompat.WearableExtender.
  3. Set wearable-specific properties using the add and set methods of NotificationCompat.WearableExtender.
  4. Call NotificationCompat.Builder.extend(NotificationCompat.Extender) to apply the extensions to a notification.
  5. Post the notification to the notification system with the NotificationManagerCompat.notify(...) methods and not the NotificationManager.notify(...) methods.
 Notification notification = new NotificationCompat.Builder(mContext)
         .setContentTitle("New mail from " + sender.toString())
         .setContentText(subject)
         .setSmallIcon(R.drawable.new_mail)
         .extend(new NotificationCompat.WearableExtender()
                 .setContentIcon(R.drawable.new_mail))
         .build();
 NotificationManagerCompat.from(mContext).notify(0, notification);

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

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