Remarks
Helper class to add wearable extensions to notifications. <p class="note"> See Creating Notifications for Android Wear for more information on how to use this class.
To create a notification with wearable extensions: <ol> <li>Create a android.app.Notification.Builder, setting any desired properties. <li>Create a android.app.Notification.WearableExtender. <li>Set wearable-specific properties using the add and set methods of android.app.Notification.WearableExtender. <li>Call android.app.Notification.Builder#extend to apply the extensions to a notification. <li>Post the notification to the notification system with the NotificationManager.notify(...) methods. </ol>
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();
