The problem is when I parse the XML from the original link for example (i am not posting the original link due to securit purpose) like http://example.com/ss.svc/APIabc?A=10&Key=XXXXX&From=19&To=221&Date=19-Apr-2016 then listview is not populated and the the logcat says error this
LogCat error-

but when the same XML is put to another server link then with the link ending with .php for example this http://www.example.in/exapmle/sub.php then its showing the parsed data to listview

Say my XML Format is like this

<APIabc
    xmlns="http://exapmle.org/">
    <APIabcd
        xmlns:a="http://ac.ssc.org/2014/21/abfaggkk"
        xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
        <Route>
            <Time>2016-04-13 06:11:00 AM</Time>
            <Avail>xyz</Avail>
            <thumb_url>http://api.androidhive.info/music/images/adele.png</thumb_url>
            <BusLabel/>
        </Route>
    </APIabcd>
</APIabc>

As logcat says error com.example.androidhive.CustomizedListView.onCreate(CustomizedListView.java:48) so the line 48 in code

NodeList nl = doc.getElementsByTagName(KEY_SONG);

What I have tried:

CustomizedListView.java

public class CustomizedListView extends Activity {
        // All static variables
        static final String URL = "http://example.com/ss.svc/APIabc?A=10&Key=XXXXX&From=19&To=221&Date=19-Apr-2016";
        // XML node keys 
        static final String KEY_SONG = "Route"; // parent node
    static final String KEY_ID = "Avail";
    static final String KEY_TITLE = "Avail";
    static final String KEY_ARTIST = "Avail";
    static final String KEY_ARTIST2 = "Avail";
    static final String KEY_DURATION = "Avail";
    static final String KEY_THUMB_URL = "thumb_url";

        ListView list;
        LazyAdapter adapter;

        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);

            ArrayList<HashMap<String, String>> songsList = new ArrayList<HashMap<String, String>>();

            XMLParser parser = new XMLParser();
            String xml = parser.getXmlFromUrl(URL); // getting XML from URL
            Document doc = parser.getDomElement(xml); // getting DOM element

            NodeList nl = doc.getElementsByTagName(KEY_SONG);
            // looping through all song nodes <song>
            for (int i = 0; i < nl.getLength(); i++) {
                // creating new HashMap
                HashMap<String, String> map = new HashMap<String, String>();
                Element e = (Element) nl.item(i);
                // adding each child node to HashMap key => value
                map.put(KEY_ID, parser.getValue(e, KEY_ID));
                map.put(KEY_TITLE, parser.getValue(e, KEY_TITLE));
                map.put(KEY_ARTIST, parser.getValue(e, KEY_ARTIST));
                map.put(KEY_DURATION, parser.getValue(e, KEY_DURATION));
                map.put(KEY_THUMB_URL, parser.getValue(e, KEY_THUMB_URL));

                // adding HashList to ArrayList
                songsList.add(map);
            }

            list=(ListView)findViewById(R.id.list);

            // Getting adapter by passing xml data ArrayList
            adapter=new LazyAdapter(this, songsList);
            list.setAdapter(adapter);

            // Click event for single list row
            list.setOnItemClickListener(new OnItemClickListener() {

                @Override
                public void onItemClick(AdapterView<?> parent, View view,
                        int position, long id) {

                }
            });
        }
    }
