How to correctly request permissions in the service?

Question

android studio

There is a code for determining coordinates over the network:

if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED
                && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            //  Toast toast = Toast.makeText(this, "Permission failed", Toast.LENGTH_SHORT);
            //   toast.show();
            return;
        } else {

            //   Toast toast = Toast.makeText(this, "is work", Toast.LENGTH_SHORT);
            //    toast.show();
        }

        LocationManager lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
        Location location = lm.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);


// GPS_PROVIDER отправить GPS
        lm.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, new MyListener());

If it's in the activity, everything is fine, everything works. But as soon as it is transferred to the MyService service, it starts to swear when permission is requested ... Maybe I'm doing something wrong?
It breaks like this:

Answer 1

There is no context.
Getcontext().getservice
But I personally don't like it when I have something hanging in the background with geolocation on my phone.
I demolish such conditionally necessary or nail services with handles
