无法从lat，long值中获取城市？

Question

Geocoder g = new Geocoder(this, Locale.getDefault()); 
    java.util.List<android.location.Address> result = null; 

    // testing 

    try{ 
     result = g.getFromLocation(43.324722,21.903333, 1); 
     if (result.size() > 0) { 
      selectedCity = result.get(0).getLocality(); 
     }else 
      //no city found 
     }catch(Exception ex) 
     { 

     } 

我用上面的代码来获得在Android的城市价值，但它始终没有显示出城市发现的任何一个指导我可能是什么问题呢？

public void getAddress(double lat, double lng) { 
    Geocoder geocoder = new Geocoder(this, Locale.getDefault()); 
    try { 
     List<Address> addresses = geocoder.getFromLocation(lat, lng, 1); 
     Address obj = addresses.get(0); 
     String add = obj.getAddressLine(0); 
     GUIStatics.currentAddress = obj.getSubAdminArea() + "," 
       + obj.getAdminArea(); 
     GUIStatics.latitude = obj.getLatitude(); 
     GUIStatics.longitude = obj.getLongitude(); 
     GUIStatics.currentCity= obj.getSubAdminArea(); 
     GUIStatics.currentState= obj.getAdminArea(); 
     add = add + "\n" + obj.getCountryName(); 
     add = add + "\n" + obj.getCountryCode(); 
     add = add + "\n" + obj.getAdminArea(); 
     add = add + "\n" + obj.getPostalCode(); 
     add = add + "\n" + obj.getSubAdminArea(); 
     add = add + "\n" + obj.getLocality(); 
     add = add + "\n" + obj.getSubThoroughfare(); 

     Log.v("IGA", "Address" + add); 
     // Toast.makeText(this, "Address=>" + add, 
     // Toast.LENGTH_SHORT).show(); 

     // TennisAppActivity.showDialog(add); 
    } catch (IOException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
     Toast.makeText(this, e.getMessage(), Toast.LENGTH_SHORT).show(); 
    } 
} 

我使用这个功能让所有的经度和纬度只是通过经度和纬度在这个函数然后你发现你的答案的相关信息。 我希望这对你很有帮助。
