Here's a snippet from a helper class I wrote to send data via POST. 

List<NameValuePair> params = new ArrayList<NameValuePair>();

params.add(new BasicNameValuePair("param1", param1));
params.add(new BasicNameValuePair("param2", param2));

DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost("http://www.blabla.com/posterome");
httpPost.setEntity(new UrlEncodedFormEntity(params));

And to get the response... 

HttpResponse httpResponse = httpClient.execute(httpPost);

Classes used in this snippet are in org.apache.http.* package.

As for JSON, JSONObject will suffice. There are examples on how to use it properly everywhere on the web. Just google it.

  • Thanks AljoshaBre,can u please tell how to handle connection time out and socket time out exceptions in detail. – srinu Jul 02 '12 at 09:28
  • Does it times out on other hosts? Did you verified if its host-specific? Perhaps you're not catching the right one? Can you include a small, concise piece of code that catches the exception? And LogCat output would be useful. I'm on my way to satisfy my stomach. I will try to help you later. – nullpotent Jul 02 '12 at 09:35

  • mHttpClient = new DefaultHttpClient(); final HttpParams params = mHttpClient.getParams(); ClientConnectionManager mgr=mHttpClient.getConnectionManager(); mHttpClient = new DefaultHttpClient( new ThreadSafeClientConnManager(params, mgr.getSchemeRegistry()),params); HttpConnectionParams.setConnectionTimeout(params, HTTP_TIMEOUT); HttpConnectionParams.setSoTimeout(params, HTTP_SOCKET_TIME_OUT); ConnManagerParams.setTimeout(params, HTTP_TIMEOUT); – srinu Jul 02 '12 at 09:46
