Code in kotlin

                val intent = Intent(this, MainActivity::class.java)
                val pendingIntent = PendingIntent.getActivity(this, 0 /* request code */, intent, PendingIntent.FLAG_UPDATE_CURRENT)


                val builder = NotificationCompat.Builder(this, title)
                .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
                .setContentText("Notification description")
                        .setSmallIcon(R.drawable.ic_mark_map)
                        .setContentIntent(pendingIntent)
                        .setOnlyAlertOnce(true)

                val mNotificationManager = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager

                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                    val channel = NotificationChannel(title,
                            "Channel human readable title",
                            NotificationManager.IMPORTANCE_DEFAULT)
                    mNotificationManager.createNotificationChannel(channel)
                }

                 val notification = builder.build()
                 startForeground(notificationID, notification)
            }

Use:

 customNotification("Title",101)
