Answer 1

LocationManager locationManager = context.getSystemService(Context.LOCATION_SERVICE);
String provider = LocationManager.GPS_PROVIDER;
Location lastKnownLocation = locationManager.getLastKnownLocation(provider);

if (null != lastKnownLocation) {
    Toast.makeText(getActivity().getApplicationContext(),String.valueOf(lastKnownLoc‌​ation.getLatitude() + lastKnownLocation.getLongitude() ),Toast.LENGTH_SHORT).show();
}

But check what does really getLastKnownLocation returns and does it fits in your application context. Otherwise you have to use listener pattern to obtain latest location.

But I strongly do not recommend to use getLastKnownLocation if you want to get latest location. You could try implement something like this:

class MyFragment extends Fragment {

    private void makeUseOfNewLocation(Location location) {
        // some magic code which uses location object
    }

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);

        LocationManager locationManager = (LocationManager)activity.getSystemService(Context.LOCATION_SERVICE);

        LocationListener locationListener = new LocationListener() {
            public void onLocationChanged(Location location) {
                makeUseOfNewLocation(location);
                locationManager.removeUpdates (this);
            }

            public void onStatusChanged(String provider, int status, Bundle extras) {}

            public void onProviderEnabled(String provider) {}

            public void onProviderDisabled(String provider) {}

        };

        locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener);
    }
}

It ensures that you always get a location object and only once.
