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 *"No
Location found Enter location correctly*" instead of crash. How can i do
this? My parsing code is here:
* * StringBuilder urlString = new StringBuilder();
urlString.append("http://maps.google.com/maps?q=";);
urlString.append(enter.getText().toString());//from
urlString.append(",dhaka");
urlString.append("&ie=UTF8&0&om=0&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()>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();
}
