Always receive org.apache.http.NoHttpResponseException: The target server failed to respond Android

I am working on HTTP post in android. Here is my code:

SendMail sending = (SendMail) new SendMail()
.execute(url + "/mob/android/dummy.php");


public class SendMail extends AsyncTask<String, String, String> {

private String endResult;

@Override
protected String doInBackground(String... val) {
String url = val[0];
Log.i("Url", url + "");

HttpClient httpclient = new DefaultHttpClient();

HttpPost httppost = new HttpPost(url);

try {

CookieStore cookieStore = new BasicCookieStore();
((AbstractHttpClient) httpclient).setCookieStore(cookieStore);

List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("name", post_name));
nameValuePairs


nameValuePairs.add(new BasicNameValuePair("email", post_email));
nameValuePairs.add(new BasicNameValuePair("message",
"Requesting appointment from: " + SelectedDr
+ " Message: " + post_message));

Log.i("nameValuePairs:", "" + nameValuePairs);

httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

HttpResponse response = httpclient.execute(httppost);
BasicResponseHandler myHandler = new BasicResponseHandler();
endResult = myHandler.handleResponse(response);
Log.i("nameValuePairs", "" + nameValuePairs);
Log.i("endResult", "" + endResult);
} catch (ClientProtocolException e) {

} catch (IOException e) {

}

return null;
}

@Override
protected void onPostExecute(String result) {

super.onPostExecute(result);
publishProgress(endResult);

}

@Override
protected void onProgressUpdate(String... values) {

super.onProgressUpdate(values);
String result = values[0];

T_warning.setText("Mail Sent.");
ET_email.setText("");
ET_name.setText("");

ET_message.setText("");





}

}


Now till

nameValuePairs.add(new BasicNameValuePair("message",
"Requesting appointment from: " + SelectedDr
+ " Message: " + post_message));


it is working fine but on HttpResponse response = httpclient.execute(httppost); it gives no reponse after 3 minutes it gives mail sent but on my mail server I received no mail and also show exception:


org.apache.http.NoHttpResponseException: The target server failed to respond


I am stuck with that I could not understand why this is happening I added all permissions

LOGCAT:

04-05 10:41:57.110: I/exception(3926): org.apache.http.NoHttpResponseException: The target server failed to respond

04-05 10:41:57.110: I/endResult(3926): null


Edited Code gives LOGCAT:

Answer

try this code within doInBackground

    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
            nameValuePairs.add(new BasicNameValuePair("name", post_name));
nameValuePairs.add(new BasicNameValuePair("email", post_email));
            nameValuePairs.add(new BasicNameValuePair("message",
                    "Requesting appointment from: " + SelectedDr
                            + "  Message: " + post_message));

        DefaultHttpClient hc = new DefaultHttpClient();
            ResponseHandler<String> res = new BasicResponseHandler();
            HttpPost postMethod = new HttpPost(url);
            String response = null;

            try {
                postMethod.setEntity(new UrlEncodedFormEntity(nameValuePairs));
            } catch (UnsupportedEncodingException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            try {
                response = hc.execute(postMethod, res);
            } catch (ClientProtocolException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
