my json class

public class jsonparser {  static inputstream = null; static jsonobject jobj = null; static string json = "";  // constructor public jsonparser() {  }  // function json url // making http post or mehtod public jsonobject makehttprequest(string url, string method,         list<namevaluepair> params) {      // making http request     try {          // check request method         if(method == "post"){             // request method post             // defaulthttpclient             defaulthttpclient httpclient = new defaulthttpclient();             httppost httppost = new httppost(url);             httppost.setentity(new urlencodedformentity(params));              httpresponse httpresponse = httpclient.execute(httppost);             httpentity httpentity = httpresponse.getentity();             = httpentity.getcontent();          }else if(method == "get"){             // request method             defaulthttpclient httpclient = new defaulthttpclient();             string paramstring = urlencodedutils.format(params, "utf-8");             url += "?" + paramstring;             httpget httpget = new httpget(url);              httpresponse httpresponse = httpclient.execute(httpget);             httpentity httpentity = httpresponse.getentity();             = httpentity.getcontent();         }                } catch (unsupportedencodingexception e) {         e.printstacktrace();     } catch (clientprotocolexception e) {         e.printstacktrace();     } catch (ioexception e) {         e.printstacktrace();     }      try {         bufferedreader reader = new bufferedreader(new inputstreamreader(                 is, "iso-8859-1"), 8);         stringbuilder sb = new stringbuilder();         string line = null;         while ((line = reader.readline()) != null) {             sb.append(line + "\n");         }         is.close();         json = sb.tostring();      } catch (exception e) {         log.e("buffer error", "error converting result " + e.tostring());     }      // try parse string json object     try {         jobj = new jsonobject(json);     } catch (jsonexception e) {         log.e("json parser", "error parsing data " + e.tostring());     }      // return json string     return jobj;  } 

}

emoticons nothing special sequence of text refer emoticons on device. while sending emoticons don't send emoticons sequence of text character associated it. once device receives it, replaces particular text right emoticons (image). (^) equivalent cake emoticons in skype.
