Samsung Electronics, and its partners, use cookies and similar technologies To see for yourself how notifications work, download the following sample application and install it on any Galaxy Watch running Wear OS Powered by Samsung. To check that notifications are enabled, in the Galaxy Wearable application, go to "Watch Settings > Notifications > App Notifications," and make sure the application is enabled in the list. To display notifications, your application must be given permission to do so through the Galaxy Wearable application on the user’s phone. The grayscale small icon must be used as the notification icon, as defined by the Android platform. To display notifications, the application must have the POST_NOTIFICATION permission. Notifications are not shown when the watch is muted or in Do Not Disturb (DND) mode.įor watch applications supporting Android 13 and higher: If you want to send notifications through a service, you must implement it as a foreground service.įor information about implementing notifications with foreground services, see Services that show a notification immediately. Since background services consume significant battery power, Samsung restricts background services from third-party applications to balance user experience and battery life. If the value of the sensor key TYPE_OFFBODY_DETECTION is "1," the watch is being worn and notifications can be triggered. To check whether the user is wearing the watch, use the SensorManager library. Notifications, including their sound or vibration, can only be triggered when the watch is being worn on the wrist. To implement notifications appropriately for Galaxy Watch, you must understand the following policies related to notification behavior: You need this notification ID to update or dismiss the notification. In the sample application, the notification is assigned a random integer value to uniquely identify the notification. notificationManager.createNotificationChannel(new NotificationChannel(CHANNEL_ID,CHANNEL_NAME, NotificationManager.IMPORTANCE_DEFAULT)) ĭisplay the notification: notificationManager.notify(100, notification) This is required for Android 8.0 and higher. setSmallIcon(R.drawable.notification_icon)Ĭreate a notification channel and assign it a unique channel ID. To define the notification properties, such as the icon, title, and text, use Notification.Builder: Notification notification= new Notification.Builder(this) The following code converts the image into a bitmap: Drawable drawable = ResourcesCompat.getDrawable(getResources(),R.drawable.notification_icon, null) īitmapDrawable bitmapDrawable = (BitmapDrawable) drawable īitmap largeIcon = bitmapDrawable.getBitmap() ![]() ![]() To implement the notification icon, store the icon image as a PNG file within the "res" folder in the project. In the application code, create an instance of the NotificationManager class: NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE) In Android Studio, to create a wearable application project, select "New Project > Wear OS > Blank Activity > Finish." To implement a basic notification for Wear OS Powered by Samsung devices: A sample application is also provided so you can examine how the code works in practice. This tutorial demonstrates how to easily implement notifications on a Galaxy Watch running Wear OS Powered by Samsung and introduces the notification policies specific to Galaxy Watch. When developing your application, you must take these policies into account when implementing notifications for the real devices that the application supports. So, implementing them in your application can greatly enhance the user experience.Ĭreating notifications on Android wearables is very simple, but for security or user experience reasons, manufacturers can have varying policies related to notifications. Notifications are a central part of many mobile applications because they keep users updated and engaged.
