Error with Geocoder.getFromLocationName method

I am trying to use geocoding to get the latitudes/longitudes of a given place by passing a street address. This is my code : 

 String addr = "Shop No. 2, Payal Cinema, Old Delhi Road, Sec-14, Gurgaon";                             
 Geocoder geocoder= new Geocoder(this, Locale.getDefault());
 List<Address> addressList = null;
 try {

          addressList = geocoder.getFromLocationName(addr, 10);

     } catch (IOException e) {}
 Address address = addressList.get(0);
 if(address.hasLatitude() && address.hasLongitude()){
 lat = address.getLatitude();
 lon = address.getLongitude();
 }

The error is in the call to gecoder.getFromLocationName(addr,10) ( I checked it through System.out.println;things don't get printed to the logcat after that line)

Here is the stack trace from LogCat:

Actually latitude and longitude not found for your address please check "addressList" is null or not if it is not null then continue like below..

 if (addressList == null)
    {
             Log.d(TAG,"Latitude and longitude not found");
    }
     else {
     Address location = addressList.get(0);
    latitude = location.getLatitude();
     longitude = location.getLongitude();
     }
