Start Service as Foreground or Not for Oreo Restriction - illegalstateexception

Question

I want to show notification only if i am in background
Basically i want to avoid the notification as much as possible, Plus i want to make sure Notification is not creating much noise and irritation(vibration) to the user
Oreo hates me starting service in background and draining battery

if (Build.VERSION.SDK_INT > Build.VERSION_CODES.N_MR1 && AmInBackground(context))
{
context.startForegroundService(intent);
showNotification();
}
else
{
context.startService(intent);
}
----------
private boolean AmInBackground(Context context){
ActivityManager activityManager =
(ActivityManager)context.getSystemService(Context.ACTIVITY_SERVICE);
ActivityManager.RunningTaskInfo foregroundTaskInfo =
activityManager.getRunningTasks(1).get(0);
String foregroundTaskPackageName = foregroundTaskInfo.baseActivity.getPackageName();
boolean same = foregroundTaskPackageName.equalsIgnoreCase(context.getPackageName());
return !same;
}
----------
Notification notification = new NotificationCompat.Builder(service, CHANNEL_ID).setContentTitle(notificationTitle)
.setContentText("Service is running in the background")
.setSmallIcon(R.drawable.icon)
.setOnlyAlertOnce(true)
.setSound(null)// No Sound
.setVibrate(null) // No Vibration
.setDefaults(~DEFAULT_SOUND) // Remove Default sound
.setDefaults(~DEFAULT_VIBRATE) // Remove Default Vibration
.build();
I Kill my service once my work is done, This will help in pull off my notification from the notification bar.
I use startForegroundService only if my work is dependent on some other task.
If i have a independent task and full control of what to do and when to do.
then i use job scheduler Api, its pretty cool, with Back off logic
