Method to parse this as the xml file and read in the method.

public HashMap doDomParsing(String strUrl, String strParent, String[] child)
{
       HashMap hmap, hmapchild = null;
       URL url;
       hmap = new HashMap();
       
       try
       {
           //url = new URL(strUrl);
           
           DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
           DocumentBuilder db = dbf.newDocumentBuilder();

          Document doc = db.parse(new InputSource(getClass().getResourceAsStream("/res/raw/parse.xml")));

           
           NodeList nodeList = doc.getElementsByTagName("item");
           for (int i = 0; i < nodeList.getLength(); i++)
           {
               
               Node node = nodeList.item(i);
               NodeList properties = node.getChildNodes();
               
               hmapchild = new HashMap();
               
               for(int j=0 ; j < properties.getLength() ; j++)
               {
                   Node property = properties.item(j);
                   String nodename = property.getNodeName();
                   Log.e("Node NAME", nodename);
                   
                   for(int inew =0 ;inew < child.length ; inew++)
                   {
                       if(nodename.equalsIgnoreCase(child[inew]))
                       {
                           hmapchild.put(nodename, property.getFirstChild().getNodeValue());
                       }
                   }
               }
               hmap.put(i, hmapchild);
           }
       }
       catch (Exception e)
       {
           // TODO Auto-generated catch block
           e.printStackTrace();
       }
       
       return  hmap;
}

How to get the battery level And the phone number of the phone

For the bettery level of the phone we need to write the following code.

private void batteryLevel() {
             BroadcastReceiver batteryLevelReceiver = new BroadcastReceiver() {
                       public void onReceive(Context context, Intent intent) {
                                    context.unregisterReceiver(this);
                                    int rawlevel = intent.getIntExtra("level", -1);
                                    int scale = intent.getIntExtra("scale", -1);
                                    int level = -1;
                                    if (rawlevel >= 0 && scale > 0) {
                                                       level = (rawlevel * 100) / scale;
                                    }
             batterLevel.setText("Battery Level Remaining: " + level + "%");
         }
        };
   IntentFilter batteryLevelFilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
   registerReceiver(batteryLevelReceiver, batteryLevelFilter);
}


Here level indicates the bettery level of the phone.


For getting the phone number of the phone we have to insert the following code...


TelephonyManager phoneManager = (TelephonyManager) getApplicationContext()                            

                                                                     .getSystemService(Context.TELEPHONY_SERVICE);

String phoneNumber = phoneManager.getLine1Number();

Here phoneNumber indicates the number of the current phone.
