地理編碼器是否在仿真器上工作

我使用的是地理編碼器，它在我的設備上工作得很好，但在仿真器上工作並沒有在2.2和4.2.2上嘗試過。地理編碼器是否在仿真器上工作

這是我的代碼：

Geocoder myLocation = new Geocoder(AzanTime.this, Locale.getDefault()); 
       List<Address> myList=null; 
       try { 
        myList = myLocation.getFromLocation(latitude,longitude, 1); 
       } catch (IOException e) { 
        // TODO Auto-generated catch block 
        e.printStackTrace(); 
       } 
       Address address = (Address) myList.get(0); 
       String addressStr = ""; 
       if(address.getAddressLine(0)!=null){ 
        addressStr += address.getAddressLine(0); 

       }

而且logcat的：
