Question

hay im new in kotlin and i try to push notification in my app. Unfortunately I'm having this error: "getSystemServise unresolved reference" this is my code:

        val intent = Intent()
        val pendingIntent = PendingIntent.getActivity(this.activity,0,intent,0)
        val notification = Notification.Builder(this.activity)
                .setContentTitle("time is:")
                .setContentText("text")
                .setSmallIcon(R.drawable.notification_icon_background)
                .setContentIntent(pendingIntent)

        val nm:NotificationManager = getSystemService(Context.NOTIFICATION_SERVICE);
        nm.notify(0,notification.build())

thanks for helpers

I was also facing the same issue.
I got the partial solution with the previous answers, but there is one more thing that you have to mention, i.e. that the variable is nullable or not and put the operators accordingly:

val downloadManager = context?.getSystemService(Context.DOWNLOAD_SERVICE) as DownloadManager?
