I wonder if it's possible to get a location without Google Services and without using GPS (and thus using NETWORK_PROVIDER) on an Android device. My current code looks like this:

public void onButtonTap(View view) {

LocationListener locationListener = new LocationListener() 
 public void onLocationChanged(Location location) 
 // we're done here
 printLocation(location);
 
 public void onStatusChanged(String provider, int status, Bundle extras) 
 public void onProviderEnabled(String provider) 
 public void onProviderDisabled(String provider) 
;

String provider = LocationManager.NETWORK_PROVIDER;
LocationManager locationManager = (LocationManager) getApplicationContext().getSystemService(LOCATION_SERVICE);
Location location = null;
try 
 location = locationManager.getLastKnownLocation(provider);
 catch (SecurityException se) 

if(location != null) 
 // we're done here
 printLocation(location);

if(location == null) 
 try 
 locationManager.requestSingleUpdate(provider, locationListener, null);
 catch (SecurityException se) 
 
 // end of onButtonTab (formatting issues)

private void printLocation(Location location) 
 String latitude = String.format(Locale.US, "%.4f", location.getLatitude());
 String longitude = String.format(Locale.US, "%.4f", location.getLongitude());
 String slocation = "lat: " + latitude + ", lon: " + longitude;
 Toast.makeText(getApplicationContext(), slocation, Toast.LENGTH_LONG).show();

So I basically query for the last location and if there's none I request an update. This works for PASSIVE_PROVIDER (if there's GPS activity) and of course for GPS_PROVIDER but I don't get a location with NETWORK_PROVIDER. The listeners method onLocationChanged never gets called. The app has the right permissions and locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER) is true.

Is this functionality just not working because there's no database (owned by Google and provided by Google Services) to compare against? Or does AOSP build it's own database over time (learning from GPS Data)? I doubt the later.

Little extra question: I can't use Fused Location Provider API as I don't have Google Services installed, can I?
