android - Volley - no response from the URL -

i unable response url hitting using volley library, please can me out ?

i getting on emulator : "com.android.volley.noconnectionerror:java.io.ioexception:content length promised 45 bytes, received 0 ."

i have pasted code below:

string url = "http://ipchicken.com"

    jsonobjectrequest jsobjrequest = new jsonobjectrequest(             request.method.post, url, null,             new response.listener<jsonobject>() {                  @override                 public void onresponse(jsonobject response) {                     // todo auto-generated method stub                     sampletext.settext("response => " + response.tostring());                   }             }, new response.errorlistener() {                  @override                 public void onerrorresponse(volleyerror error) {                     // todo auto-generated method stub                     sampletext.settext( error.tostring());                  }             });      queue.add(jsobjrequest); 

if constructed requestqueue hand, instead of calling volley.newrequestqueue, need call .start() on it. otherwise looks fine. thanks
