![]() ![]() ![]() Note that we need to reference the notification ID so that it can be used to acknowledge it in the reply. build ()) Ī generic method for creating a simple notification might be: // createNotification(56, R.drawable.ic_launcher, "New Message", // "There is a new message from Bob!") private void createNotification ( int nId, int iconRes, String title, String body, String channelId ) // end of minimum API version 24 checkįinally, we should create the notification. #PENDING INTENT ANDROID STUDIO UPDATE#NOTIFICATION_SERVICE ) // mId allows you to update the notification later on. Then we just have to append the notification using the NotificationManager: NotificationManager mNotificationManager = ( NotificationManager ) getSystemService ( Context. Builder mBuilder = // this Builder class is deprecated new NotificationCompat. setContentText ( "Hello World!" ) įor API level 25 and below, we create the notification without any channel: NotificationCompat. ![]() Builder mBuilder = // Builder class for devices targeting API 26+ requires a channel ID new NotificationCompat. Typically this will contain at least an icon, a title, body.įor API level 26 and above, we need to set a notification channel using the updated NotificationCompat.Builder. Let's build a basic notification using the NotificationCompat.Builder. Also, one can delete existing channels, however, be aware that they are visible in the settings app. createNotificationChannel ( channel ) Īn app can create multiple channels with different ids. ![]() NOTIFICATION_SERVICE ) mNotificationManager. setDescription ( "Reminders" ) // Register the channel with the notifications manager NotificationManager mNotificationManager = ( NotificationManager ) context. IMPORTANCE_DEFAULT NotificationChannel channel = new NotificationChannel ( "m圜hannelId", "My Channel", importance ) channel. Configure the channel int importance = NotificationManager. Creating a notification channel again with same id updates the name and description with the new values. Create the notification channel in the app's application class. Setting the description helps the user to identify the channel. Creating a Notification Channelįor API level 26 and above, we need to create a notification channel, provide a unique string id, name, and importance level. First you construct the notification using the NotificationCompat.Builder and then you add the notification to the NotificationManager.īeginning with API Level 26, a notification must belong to a channel as shown below. UsageĬreating notifications is fairly straightforward. The developers targeting API level 26 and above need to set a channel to a notification at the minimum.įor a more detailed look at the design of notifications check out the Notifications Design guide. Notifications are sorted based on the importance level of the channels. Notification channels can be enabled/disabled by the user in the Settings app or upon long clicking the notification. Starting with API level 26 (Oreo), notification channels were introduced to give more control over the notifications for users. At the minimum, all notifications consist of a base layout including: Notifications can include actions that let the user take a relevant action from within the notification drawer.
