Log.d("Network", "Network");
if (locationManager != null) {
location = locationManager
.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
if (location != null) {

longitude = location.getLongitude();
}
}
}
}
}
} catch (Exception e) {
e.printStackTrace();
}

No, it is not. getLastKnownLocation() frequently returns null, on all versions of Android.
getLastKnownLocation() is an optimization. Use it, but be prepared to rely upon onLocationChanged() for when getLastKnownLocation() returns null or an out-of-date value.
This is covered in the documentation, as well as in books and courses on Android app development.
To get the last known location all your have to do is call
mLocationClient.getLastLocation(); once the location service was connected.
