How do you tell whether the user initiated onTaskRemoved or the system did?

Question

My goal is for the user to be able to swipe an app away and shut down a foreground service. I do this by overriding onTaskRemoved. This works as expected, and I shut down my service from the method, but now there is the issue of the system shutting down the foreground service using onTaskRemoved.

Forget what setting I used, but my app is listed as exempt in the standby apps.

What can I do to stop the system from shutting down my foreground service?

I do what the developers guide says and more.

        Intent intentServiceMain = new Intent(ActivityMain.this, ServiceMain.class);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            startForegroundService(intentServiceMain);
        } else {
            startService(intentServiceMain);
        }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
            Toast.makeText(getApplicationContext(), "Service starting", Toast.LENGTH_SHORT).show();
            setUpNotificationBuilder();
            notification = notificationCompatBuilder.build();
            startForeground(NOTIFICATION_CHANNEL_ID.hashCode(), notification);
            return START_STICKY;
    }

    private void setUpNotificationBuilder() {
        notificationCompatBuilder = new NotificationCompat.Builder(
                getApplicationContext(), NOTIFICATION_CHANNEL_ID)
                .setSmallIcon(R.drawable.music_note_black_48dp)
                .setContentTitle(NOTIFICATION_CHANNEL_ID)
                .setPriority(NotificationCompat.PRIORITY_LOW)
                .setVisibility(NotificationCompat.VISIBILITY_PUBLIC)
                .setStyle(new NotificationCompat.DecoratedCustomViewStyle());
        remoteViewsNotificationLayout =
                new RemoteViews(getPackageName(), R.layout.pane_notification);
        notificationCompatBuilder.setCustomContentView(remoteViewsNotificationLayout);
        Intent notificationIntent = new Intent(getApplicationContext(), ActivityMain.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(
                getApplicationContext(), 0, notificationIntent, 0);
        notificationCompatBuilder.setContentIntent(pendingIntent);
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            int importance = NotificationManager.IMPORTANCE_LOW;
            NotificationChannel channel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, NOTIFICATION_CHANNEL_ID, importance);
            String description = "Service";
            channel.setDescription(description);
            NotificationManager notificationManager = getSystemService(NotificationManager.class);
            notificationManager.createNotificationChannel(channel);
        }
    }
