Note that to create the Handler instance, you must first initialize and start HandlerThread.

Define a call that tracks your deployed SCA as it approaches its designated destination: private fun trackToDestination(notificationBuilder: NotificationCompat.Builder) { val notificationManager = getSystemService(NOTIFICATION_ SERVICE) as NotificationManager for (i in 10 downTo 0) { Thread.sleep(1000L) notificationBuilder.setContentText( "$i seconds to destination").setSilent(true) notificationManager.notify(NOTIFICATION_ID, notificationBuilder.build()) } }
