Android Wear notification won't show up

I'm trying to use Pages and Stacks from the Android Wear SDK preview. Without the Wear code the notifications show up fine, while if I use Wear specific code I can't get a notification, neither on the phone nor on the Wear Emulator. I've gone throught the code 10 times, I think I need a fresh pair of eyes to catch the error.

This code should create, on the phone, a Notification for each Tracker (an external device sending a Message) with a list of unread Messages (using the InboxStyle). On Wear it should stack multiple Notifications grouped by Tracker, adding a Page for each unread Message.

  public static void showNewMessagesNotif(Context context, Tracker tracker, List<Message> messages) {
    String trackerName = tracker.getName() + " - " + tracker.getPhoneNumber();
    String contentTitle = context.getResources().getQuantityString(R.plurals.notif_new_messages, messages.size(), messages.size());


    Intent callIntent = new Intent(Intent.ACTION_CALL);
    callIntent.setData(Uri.parse("tel:" + tracker.getPhoneNumber()));
    PendingIntent callPendingIntent = PendingIntent.getActivity(context, 0, callIntent, 0);


    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context)
            .setSmallIcon(R.drawable.ic_action_location_searching)
            .setContentTitle(contentTitle)
            .setContentText(trackerName)
            .setAutoCancel(true)
            .addAction(R.drawable.ic_action_call, context.getString(R.string.action_call), callPendingIntent);
    NotificationCompat.InboxStyle inboxStyle =
            new NotificationCompat.InboxStyle();
    // Sets a title for the Inbox style big view
    inboxStyle.setBigContentTitle(contentTitle);

    // Moves events into the big view
    for (Message message : messages) {
        inboxStyle.addLine(message.getText());
    }
    inboxStyle.setSummaryText(trackerName);
    // Moves the big view style object into the notification object.
    mBuilder.setStyle(inboxStyle);

    mBuilder.setContentIntent(getNotificationIntent(context, tracker));
    // Issue the notification here.
    NotificationManagerCompat notificationManager =
            NotificationManagerCompat.from(context);

    int notifId = (int) (NEW_MESSAGE_NOTIF_BASE_ID + tracker.getRowId());

//Android Wear Notifications
    List<Notification> wearPages = new ArrayList<Notification>();

    for (Message message : messages) {
        NotificationCompat.BigTextStyle extraPageStyle = new NotificationCompat.BigTextStyle();
        extraPageStyle.setBigContentTitle(message.getText())
                .bigText(message.getAddress());
        Notification extraPageNotification = new NotificationCompat.Builder(context)
                .setStyle(extraPageStyle)
                .build();


        wearPages.add(extraPageNotification);
    }


    WearableNotifications.Builder wearNotificationBuilder =
            new WearableNotifications.Builder(mBuilder)
                    .setHintHideIcon(true)
                    .setGroup(GROUP_BY_TRACKER).addPages(wearPages);


    // mId allows you to update the notification later on.
    notificationManager.notify(notifId, wearNotificationBuilder.build());
}

For stacking notifications, you create and notify multiple notifications

  • For each stacked notification that you want to appear on Wear, notify a notification where you've called setGroup(trackerGroupId)
  • For the summary notification that you want to appear on the phone/tablet, notify a notification where you've called setGroup(trackerGroupid, WearableNotifications.GROUP_ORDER_SUMMARY)

I think your problem is that you must have a summary notification for any notifications to appear on either device.
