Add android:foregroundServiceType="mediaProjection" to the element in the manifest for your service and this issue will be gone.

This is the solution after some time of research. First of all, follow the other answers.

  1. manifest permission
  2. start service on the foreground

this is the answer that I had

  1. On the service, onStartCommand(), I implemented this method for the android Q. (less than Q, it works without this codes): startForeground(id, notification, serviceType)
public int onStartCommand(Intent intent, int flags, int startId) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
            Notification notification = ScreenRecorderHelper.GetMediaProjectionNotification(AppShared.gContext);
            startForeground(startId,
                    notification,
                    ServiceInfo.FOREGROUND_SERVICE_TYPE_MEDIA_PROJECTION);
        }



        handleCommand(intent);
        // We want this service to continue running until it is explicitly
        // stopped, so return sticky.
        return START_STICKY;
    }

I hope this helps many others like me...
