Does Android Geocoder work only with internet connection?

Question

I'm trying to get the clicked address on a Google Map with the onMapLongClickListener(LatLng point), using the lat and the lng of the point and converting them in a address with a Geocoder.It works fine if I am connected to Internet, but if I'm not the app crashes because the getFromLocation method gives a null result. So I suppose that the Geocoder class works only with the connection is enabled.Is it so?And is there a way to get the adress staying offline?

That's the code of the method:

public void onMapLongClick(LatLng point) {
            List<Address> addresses = null;
            try {
                addresses = geocoder.getFromLocation(point.latitude, point.longitude, 1);
            } catch (IOException e) {
                e.printStackTrace();
            }
            String address = addresses.get(0).getAddressLine(0);
            String city = addresses.get(0).getAddressLine(1);
            String country = addresses.get(0).getAddressLine(2);
            String str = address + ", " + city + ", " + country;
            gMap.addMarker(new MarkerOptions()
            .position(point)
            .title("Clicked Point")
            .draggable(false)
            .snippet(address + ", " + city + ", " + country));
            Vibrator v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
            v.vibrate(50);
        }    

And these are the permissions:

<uses-permission android:name="com.example.mappine.permission.MAPS_RECEIVE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.VIBRATE" />

Yes. Do you know how much data is needed for the full geocoder? You aren't storing that on a cellphone.
