problem in sending a SOAP request

I am using the follwing code to send SOAP request.

 String str = new StringBuilder("POST /WrenchTelLink/WrenchENTService.asmx HTTP/1.1\n")
              .append("Host: 59.160.183.14\n")
              .append("Content-Type: text/xml; charset=utf-8\n")
              .append("Content-Length: LLLLLL\n")
              .append("SOAPAction: \"http://WrenchGlobal/GetToDoList\"\n ")
              .append("<?xml version=\"1.0\" encoding=\"utf-8\"?>")
              .append("<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-      
               instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" 
               xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">\n")
              .append("<soap:Body>\n")
              .append("<GetToDoList xmlns=\"http://WrenchGlobal/\">\n")
              .append("<viPeriod>IIIIII</viPeriod>\n")
              .append("<vsUserID>SSSSSS</vsUserID>\n")
              .append("</GetToDoList>\n")
              .append("</soap:Body>\n")
              .append("</soap:Envelope>\n").toString();
 String temp = str.replaceAll("LLLLLL",Integer.toString(str.length()))
   .replaceAll("SSSSSS",ph).replaceAll("IIIIII",Integer.toString(period));
  HttpClient httpclient = new DefaultHttpClient();
  HttpPost httppost = new HttpPost(url);

  try
   {
      StringEntity se = new StringEntity(temp,HTTP.UTF_8);

      se.setContentType("text/xml");  
      httppost.setHeader("Content-Type","application/soap+xml;charset=UTF-8");

      httppost.setEntity(se);  
      BasicHttpResponse httpResponse = (BasicHttpResponse)httpclient.execute(httppost);

      if(httpResponse.getStatusLine().toString()!="") 
         Toast.makeText(TelLinkActivity.this, httpResponse.getStatusLine().toString()
                    , Toast.LENGTH_SHORT).show();
      else
          Toast.makeText(TelLinkActivity.this,"Failed", Toast.LENGTH_SHORT).show();

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

Its not showing any of the TOAST messages. I am not getting what i am supposed understand from this. Its not working at all. Could anyone tell me if there is something wrong with the code..?

show Toast in ui thread, by runOnUiThread for example

runOnUiThread(new Runnable() {
    public void run() {
      Toast.makeText(TelLinkActivity.this,"Failed", Toast.LENGTH_SHORT).show();
    }
});
