使用

 var intent = Intent(this@MainActivity, UpdateService::class.java).apply {putExtra(UpdateService.URL, it.downloadUrl)putExtra(UpdateService.ICON, R.drawable.ic_launcher)}if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {this@MainActivity.startForegroundService(intent)} else {this@MainActivity.startService(intent)}
