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 extend 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();
