Adding Pages to a Notification

When you'd like to provide more information without requiring users to open your app on their handheld device, you can add one or more pages to the notification on the wearable. The additional pages appear immediately to the right of the main notification card.

To create a notification with multiple pages:

1. Create the main notification (the first page) with NotificationCompat.Builder, in the way you'd like the notification to appear on a handset.
2. Create the additional pages for the wearable with NotificationCompat.Builder.
3. Apply the pages to the main notification with the addPage() method or add multiple pages in a Collection with the addPages() method.

For example, here's some code that adds a second page to a notification:

// Create builder for the main notification
NotificationCompat.Builder notificationBuilder =
        new NotificationCompat.Builder(this)
        .setSmallIcon(R.drawable.new_message)
        .setContentTitle("Page 1")
        .setContentText("Short message")
        .setContentIntent(viewPendingIntent);

// Create a big text style for the second page
BigTextStyle secondPageStyle = new NotificationCompat.BigTextStyle();
secondPageStyle.setBigContentTitle("Page 2")
               .bigText("A lot of text...");

// Create second page notification
Notification secondPageNotification =
        new NotificationCompat.Builder(this)
        .setStyle(secondPageStyle)
        .build();

// Add second page with wearable extender and extend the main notification
Notification twoPageNotification =
        new WearableExtender()
                .addPage(secondPageNotification)
                .extend(notificationBuilder)
                .build();

// Issue the notification
notificationManager =
        NotificationManagerCompat.from(this);
notificationManager.notify(notificationId, twoPageNotification);
