I understand that some answers like this one seem to have covered this, but I believe I'm following the procedure exactly and still get the warning. In my app, I want one channel for the foreground notification that's always there and another for push notifications to go through separately. Here's my code:

private void startNotifications()
 if (Build.VERSION.SDK_INT >= 26) 
 NotificationChannel channel = new NotificationChannel(getResources().getString(R.string.ForegroundID),
 getResources().getString(R.string.foreground_channel_name), NotificationManager.IMPORTANCE_LOW);
 NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
 channel.setDescription(getResources().getString(R.string.foreground_channel_description));
 channel.setShowBadge(false);
 channel.setSound(defaultSound, null);
 //TODO Another nonsense warning over here, is there a way to fix it?
 notificationManager.createNotificationChannel(channel);

 NotificationChannel channel2 = new NotificationChannel(getResources().getString(R.string.PushID),
 getResources().getString(R.string.push_channel_name), NotificationManager.IMPORTANCE_HIGH);
 channel.setDescription(getResources().getString(R.string.push_channel_description));
 channel.setShowBadge(false);
 channel.setSound(defaultSound, null);
 notificationManager.createNotificationChannel(channel2);
 
 Notification foregroundNotification = createNotification();
 //Must be called within 5 seconds of Service being started or else Android will crash the app
 startForeground(ONGOING_NOTIFICATION_ID, foregroundNotification);

It calls

private Notification createNotification()
 String[] initialData = getNotificationInfo();
 Intent notificationIntent = new Intent(this, MainActivity.class);
 PendingIntent activityPendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);

 Intent closeService = new Intent(this, MainActivity.class);
 closeService.setAction(getResources().getString(R.string.IntentAction_CloseService));
 closeService.putExtra(getResources().getString(R.string.IntentExtra_CloseService), getResources().getString(R.string.Intent_CloseFromNotification));
 PendingIntent closePendingIntent = PendingIntent.getActivity(this, 0, closeService, 0);
 NotificationCompat.Builder builder = new NotificationCompat.Builder(this, getResources().getString(R.string.ForegroundID))
 .setSmallIcon(R.drawable.pic_small)
 .setContentTitle(initialData[0])
 .setContentText(initialData[1])
 .setContentIntent(activityPendingIntent)
 .setShowWhen(false)
 .setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
 .setPriority(NotificationCompat.PRIORITY_DEFAULT)
 .setCategory(NotificationCompat.CATEGORY_SERVICE)
 .setColor(getResources().getColor(R.color.picGray))
 .setSound(defaultSound)
 .addAction(R.drawable.pic_small, getResources().getString(R.string.end_service_text), closePendingIntent);
 return builder.build();

And throughout the lifescycle of the app, I update the foreground notification with:

private void updateForegroundNotification ()
 Log.i("BLE_Service", "Updating Foreground Notification!");
 Notification updatedNotification = createNotification();
 NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
 mNotificationManager.notify(ONGOING_NOTIFICATION_ID, updatedNotification);

But whenever the foreground notification updates, I get the warning about stream types being deprecated and setSound() and all that. What's going on?
