	createNotificationChannel()
	val btn = findViewById<Button>(R.id.btn_button)
	btn.setOnClickListener {
	sendNotification()
	}
	}
	private fun createNotificationChannel(){
	if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
	val name = "Notification Title"
	val descriptionText = "Notification Description"
	val importance = NotificationManager.IMPORTANCE_DEFAULT
	val channel = NotificationChannel(CHANNEL_ID, name,importance).apply {
	description = descriptionText
	}
	val notificationManager : NotificationManager = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
	notificationManager.createNotificationChannel(channel)
	}
	}
	private fun sendNotification(){
	val builder = NotificationCompat.Builder(this, CHANNEL_ID)
	.setSmallIcon(R.drawable.ic_launcher_background)
	.setContentTitle("title")
	.setContentText("desc")
	.setPriority(NotificationCompat.PRIORITY_DEFAULT)
