you can use below method sending json request.

public static httpresponse sendrequest(string url, string request) throws exception  {     //create httpclient make request     defaulthttpclient httpclient = new defaulthttpclient();      //create httppost request object     httppost httpost = new httppost(url);      //create string entity passed httppost request     stringentity se = new stringentity(request));      //set created stringentity     httpost.setentity(se);      //the intended     httpost.setheader("accept", "application/json");     httpost.setheader("content-type", "application/json");      return httpclient.execute(httpost); } 

hope helps.
