Also, one can delete existing channels, however, be aware that they are visible in the settings app. Let's build a basic notification using the NotificationCompat.Builder. 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. setContentText ( "Hello World!" ) įor API level 25 and below, we create the notification without any channel: NotificationCompat.īuilder mBuilder = // Builder class for devices targeting API 26+ requires a channel ID new NotificationCompat. Builder mBuilder = // this Builder class is deprecated new NotificationCompat. Then we just have to append the notification using the NotificationManager: NotificationManager mNotificationManager = ( NotificationManager ) getSystemService ( Context. NOTIFICATION_SERVICE ) // mId allows you to update the notification later on. 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. Note that we need to reference the notification ID so that it can be used to acknowledge it in the reply.
