why Geocoder.getFromLocationName(...) returns an empty list?

I'm using the android.location.Geocoder for the first time. The Idea is: I have a Listener on a button which takes input from an EditText and resolve the location. Up to now it's debugging phase, so I have no handler taking messages from the thread, only geocoding and write to logcat. Q: Why this method always returns an empty list of Address objects?

private View.OnClickListener checkLocation = new View.OnClickListener() {       

    @Override
    public void onClick(View v) {
        location = ((EditText)findViewById(R.id.getLocation)).getText().toString();
        Thread thr = new Thread(){
            public void run (){

                Geocoder gc = new Geocoder(ctx,Locale.ITALY);
                try {
                    fa= gc.getFromLocationName(location, 3);
                    if (fa.isEmpty())Log.d("getFromLocationName", "NothingFound");
                    else
                    {
                        int size= fa.size();
                        for (int i = 0; i<size ;i++)
                            Log.d("getFromLocationName.at("+ String.valueOf(i) +")", fa.get(i).getAddressLine(0)+", "+fa.get(0).getAddressLine(1));
                    }
                } catch (IOException e) {
                    Log.e("IOException", e.getMessage());
                }

            }
        };
        thr.start();

    }
};

Somebody knows why? (btw I am using 1.6 sdk) Input tried

the project wasn't targeting the correct AVD. To use geolocation you have to make it point an avd implementing the google APIs. Once I changed it everything worked just fine. Sorry for bothering

Because it doesn't recognize the address you are putting in or it can't reach the service.

What address are you putting in? Try something as simple as a zip code or city or state name.
