Things to take care of �think before acting

Keep in mind

Read the design guidelines

Be context aware

Show relevant actions

Think before you notify

Wearable special functionality

Some code snippets �

Wearable only functionality

// Create a NotificationCompat.Builder for standard notification features NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(mContext) .setContentTitle("New mail from " + sender.toString()) .setContentText(subject) .setSmallIcon(R.drawable.new_mail); // Create a WearablesNotification.Builder to add special functionality for wearables

Notification notification = new WearableNotifications.Builder(notificationBuilder) .setHintHideIcon(true) .build();

Adding actions

NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this) .setSmallIcon(R.drawable.ic_event) .setContentTitle(eventTitle) .setContentText(eventLocation) .setContentIntent(viewPendingIntent) .addAction(R.drawable.ic_map, getString(R.string.map),

mapPendingIntent);

Multipage notifications

// Create builder for the main notification NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)…… // 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(); // Create main notification and add the second page Notification twoPageNotification = new WearableNotifications.Builder(notificationBuilder) .addPage(secondPageNotification) .build();

Stacked notifications

Notification notif1 = new WearableNotifications.Builder(builder) .setGroup(GROUP_KEY_EMAILS) .build(); // Issue the notification NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this); notificationManager.notify(notificationId1, notif); builder = new NotificationCompat.Builder(mContext) .setContentTitle("New mail from " + sender2) .setContentText(subject2) .setSmallIcon(R.drawable.new_mail); // Use the same group as the previous notification Notification notif2 = new WearableNotifications.Builder(builder) .setGroup(GROUP_KEY_EMAILS) .build(); notificationManager.notify(notificationId2, notif);
