            return;
        }
        if (resultCode != RESULT_OK) {
            Toast.makeText(this,
                    "Screen Cast Permission Denied", Toast.LENGTH_SHORT).show();
            return;
        }
        mMediaProjectionCallback = new MediaProjectionCallback();

        mMediaProjection = mProjectionManager.getMediaProjection(resultCode, data);

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...

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