Unable to handle error in google map parsing
<p>I am able to parse google map according to location name. Now my problem is when i enter a wrong location in my editbox and press enter button it crashes. I want: when no location is found then it will show a message <strong>"No Location found Enter location correctly</strong>" instead of crash. How can i do this? My parsing code is here:</p>

<pre><code>            StringBuilder urlString = new StringBuilder();
            urlString.append("http://maps.google.com/maps?q=");
            urlString.append(enter.getText().toString());//from
            urlString.append(",dhaka");
            urlString.append("&amp;ie=UTF8&amp;0&amp;om=0&amp;output=kml");
            Log.d("xxx","URL="+urlString.toString());
            // get the kml (XML) doc. And parse it to get the coordinates(direction route).
            Document doc = null;
            HttpURLConnection urlConnection= null;
            URL url = null;
            try
            {
            url = new URL(urlString.toString());
            urlConnection=(HttpURLConnection)url.openConnection();
            urlConnection.setRequestMethod("GET");
            urlConnection.setDoOutput(true);
            urlConnection.setDoInput(true);
            urlConnection.connect();

            DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
            DocumentBuilder db = dbf.newDocumentBuilder();
            doc = db.parse(urlConnection.getInputStream());
            if(doc.getElementsByTagName("Point").getLength()&gt;0)
            {
                String path = doc.getElementsByTagName("Point").item(0).getFirstChild().getFirstChild().getNodeValue() ;
                Log.d("xxx","path="+ path);
                String [] pairs = path.split(" ");
                lngLat = pairs[0].split(","); 

            }

            }
            catch (MalformedURLException e)
            {
                      e.printStackTrace();

            }
            catch (IOException e)
            {
            e.printStackTrace();

            catch (ParserConfigurationException e)
            {
               e.printStackTrace();

            }
            catch (SAXException e)
            {
                           e.printStackTrace();
            }
