Code behaves differently on two different network type

Issue

I have following code for testing the server connectivity.
I have a device that has Ethernet as well as Wi-fi connectivity.

When user switch network from Ethernet to wifi or vise verse, i do the test for server connectivity and i check if my server is reachable or not with the new network.

I have following code:

public class TestActivity extends Activity
{
    Button test_btn = null;

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

        test_btn = (Button)findViewById(R.id.testButton);
        test_btn.setOnClickListener( new OnClickListener() 
        {
            public void onClick(View v) 
            {
                Log.d("TestApp", "onClick Starting Test");
                startTest();
            }
        });
    } 

    void startTest()
    { 
        ServerTestThread mServerTestThread = new ServerTestThread()
        mServerTestThread.start();
    }

    class ServerTestThread extends Thread 
    {
        boolean result = false;
        public void run() 
        {   
             boolean result = false;
             HttpGet request = new HttpGet("www.MyServer.com");
             HttpParams httpParameters = new BasicHttpParams();
             HttpClient httpClient = new DefaultHttpClient(httpParameters);

             try
             {
                 HttpConnectionParams.setConnectionTimeout(httpParameters, 6000);
                 HttpConnectionParams.setSoTimeout(httpParameters, 6000); 
                 HttpResponse response = httpClient.execute(request);

                 int status = response.getStatusLine().getStatusCode();
                 if (status == HttpStatus.SC_OK) 
                 {
                     result = true;
                 }
             }
             catch(Exception e)
             {
                 e.printStackTrace();
                 result = false;
             }

             Log.d("TestApp", "Ping Result:"+result);
        }
    }

}

This code works fine on my device when i connect my device to internet using Ethernet connectivity, but when i switch from Ethernet to WI-FI this code gives me false result every time.

Using wi-fi i am able to ping to MyServer using the android browser, but from my application i am not able to ping to my server.

Do i need to add something extra to my code to make it work for wifi and Ethernet?

I have also Tried to with InetAddress.getByName("www.MyServer.com").isReachable(timeout) but it also giving me the same results.

Is there any reliable way of implementing ping in Android which will work across differnt platforms.

Solution

sorry use this one

class ServerTestThread extends Thread 
{
boolean result = false;
public void run() 
{   
     boolean result = false;
     HttpGet request = new HttpGet("www.MyServer.com");
     HttpParams httpParameters = new BasicHttpParams();


     try
     {
         HttpConnectionParams.setConnectionTimeout(httpParameters, 6000);
         HttpConnectionParams.setSoTimeout(httpParameters, 6000); 
         HttpClient httpClient = new DefaultHttpClient(httpParameters);///write this line below  
         HttpResponse response = httpClient.execute(request);

         int status = response.getStatusLine().getStatusCode();
         if (status == HttpStatus.SC_OK) 
         {
             result = true;
         }
     }
     catch(Exception e)
     {
         e.printStackTrace();
         result = false;
     }

     Log.d("TestApp", "Ping Result:"+result);
}

}
