如何在Android模拟器中使用经度和纬度获取完整的地方地址？

Question

This is my code It don't have any error but

It shows in textView "No Address returned!"

double lat = 18.520430300000000000, log = 73.856743699999920000;
    String address = null;                                                 
    Geocoder geocoder = new Geocoder(this, Locale.getDefault());
    StringBuilder sb = null;
    try {
        List<Address> addresses = geocoder.getFromLocation(lat, log, 1); 
        sb = new StringBuilder(); 
        if (addresses.size() > 0) { 

           Address address = addresses.get(0); 

           for (int i = 0; i < address.getMaxAddressLineIndex(); i++) 
              sb.append(address.getAddressLine(i)+ ",");
           txtAdd.setText("Address :"+sb);
        }
        else{
            txtAdd.setText("No Address returned!");
        }
    } catch (Exception e) {

The doku gives one hint, maybe this should help

http://developer.android.com/reference/android/location/Geocoder.html

Returns an array of Addresses that are known to describe the area immediately surrounding the given latitude and longitude. The returned addresses will be localized for the locale provided to this class's constructor.

The returned values may be obtained by means of a network lookup. The results are a best guess and are not guaranteed to be meaningful or correct. It may be useful to call this method from a thread separate from your primary UI thread.
