How can I interrupt getCurrentLocation method (Codename One Location Manager)?

Question

My app features a map and when the user long presses on it, I need the current phone location to appear on the map. As @Chen advised it looks like getCurrentLocation() is the proper method to use in my case. Please note that I don't want to use a LocationListener because I want the user to have control on when they want to update their location.

Moreover I chose this manual location update because @Shai-Almog discouraged location polling. So after reading this post I first set the timeout to 20 s as written below to get the current phone location :

                Dialog ip = new InfiniteProgress().showInifiniteBlocking();
                Location currentLocation = locationManager.getCurrentLocationSync(
                        ParametresGeneraux.LOCATION_TIMEOUT_MILLI);
                // We try to get something
                if (currentLocation == null) {
                    currentLocation = locationManager.getLastKnownLocation();
                }
                ip.dispose();

But it was not sufficient and the last known location was "always" provided (I did not count maybe 5 times in a row) although the little location icon appeared in the toolbar. So I set it to 40 s but the actual current location did not come either after this twice as big amount of time (only the last known location which is > 2km away was provided).

However if I start Google Maps on Android (KitKat), the location is instantaneously accurate. And then if I go back to my app and press the map the current location is found. Actually I found a post dealing with a difference in accuracy between Google Maps and Android API but it was pertaining to Shangai / China, not the EU (France).

Consequently my question is twofold :

first how can there be such a huge difference on the same device between Google Maps and Codename One ?
then if I don't set a timeout to getCurrentLocation() how can I interrupt the location searching when the user is fed up waiting ?

Any help appreciated,

BR

Instant location will work if the Google Maps location services is turned on. If you enabled or disabled one of the android.playService build hints you must also enable android.playService.location=true to get the fast location service used by maps.
