How to get GPS location in OSMDroid without Internet connection?

Question

I made a little app in Android using OSMDroid library, my map is loading from assets. Now I want to put my GPS location on that map, but without using Internet connection. I found these

GpsMyLocationProvider provider = new GpsMyLocationProvider(getApplicationContext());
        provider.addLocationSource(LocationManager.GPS_PROVIDER);
        MyLocationNewOverlay myLocationNewOverlay = new MyLocationNewOverlay(provider, mapView);
        myLocationNewOverlay.enableMyLocation();
        Toast.makeText(getApplicationContext(),"my location "+        provider.getLastKnownLocation()
                ,Toast.LENGTH_LONG).show();
        mapView.getOverlays().add(myLocationNewOverlay);

but nothing changes.

... but without using Internet connection...

It depends on the positioning chip in your mobile device, if it was a:-

• Fully autonomous GPS chip: power-hungry, works without cellular connection, but performs poorly in urban jungle.
• Fully assisted GPS chip (A-GPS): must download "initialization" data from cellular network/connection, power-saving, performs fairly well in urban jungle.
• Hybrid - functions as A-GPS if connected to cellular network, or if orbital information is made available via a file, or functions as fully autonomous GPS in the absence of cellular network/connection.

Hybrid GPS/A-GPS were offered in premium range of Windows CE mobile phones in the old days. But these days, all iOS and almost all Android mobile devices are fully A-GPS.
