I have written the following code.
public void postSMS(String type,String phone,String body)
{
//----------------------postSMS-------------------------------
// Create a new HttpClient and Post Header
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://192.168.15.105:6543/data_in");
try {
// Add your data
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(3);
nameValuePairs.add(new BasicNameValuePair("type", type));
nameValuePairs.add(new BasicNameValuePair("body", body));
nameValuePairs.add(new BasicNameValuePair("toRfrom", phone));
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
// Execute HTTP Post Request
//HttpResponse response = httpclient.execute(httppost);
ResponseHandler<String> responseHandler=new BasicResponseHandler();
String responseBody = httpclient.execute(httppost, responseHandler);
JSONObject response=new JSONObject(responseBody);
}
catch (ClientProtocolException e) {
// TODO Auto-generated catch block
} catch (IOException e) {
// TODO Auto-generated catch block
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
What's the error and how to resolve it? Since my server is working fine but it's the client that's not sending data.(i am using python's PYCK framework on server.)
UPDATE: yes I have added INTERNET permission in the manifest ...
Following is the error log:

android.os.NetworkOnMainThreadException That's the problem.
You need to run everything that use Internet on a background Thread.
You can use AsyncTask, runnable or just create a new Thread, the best way will be surely the first one.
