httpWebRequest z c# w javie

Spedziłem cały wczorajszy wieczór nad tym i nie moge zanleźć rozwiązania. Mam takie zapytanie napisane w C#:

public void GetData()
        {
            WebRequest webRequest;
            webRequest = WebRequest.Create("http://myserviceurl" + Stopwatch.GetTimestamp().ToString() + "");
            webRequest.Method = "POST";
            webRequest.ContentType = "application/x-www-form-urlencoded";
            webRequest.BeginGetRequestStream(new AsyncCallback(GetRequestStreamCallback), webRequest);
        }

    public void GetRequestStreamCallback(IAsyncResult asynchronousResult)
    {
        HttpWebRequest webRequest = (HttpWebRequest)asynchronousResult.AsyncState;
        Stream postStream = webRequest.EndGetRequestStream(asynchronousResult);
        string json = "{\"request\":\"" +itemId+"\"}";
        string postData = "method=findTimes&p0=" + json + "";
        byte[] byteArray = Encoding.UTF8.GetBytes(postData);
        postStream.Write(byteArray, 0, byteArray.Length);
        postStream.Close();
        webRequest.BeginGetResponse(new AsyncCallback(GetResponseCallback), webRequest);
    }

    public void GetResponseCallback(IAsyncResult asynchronousResult)
    {
        try
        {
            HttpWebRequest webRequest = (HttpWebRequest)asynchronousResult.AsyncState;
            HttpWebResponse response;
            response = (HttpWebResponse)webRequest.EndGetResponse(asynchronousResult);
            Stream streamResponse = response.GetResponseStream();
            StreamReader streamReader = new StreamReader(streamResponse);
            var Response = streamReader.ReadToEnd();
            streamResponse.Close();
            streamReader.Close();
            response.Close();
            if (Response == "")
            {

            }
            else
            {
                Dispatcher.BeginInvoke(() => { DecodeResponse(Response.ToString()); });
            }
        }
        catch (WebException)
        {
            //error    
        }
    }

Próbuję zrobić z tego zapytanie w Androidzie.

public void GetData()
    {
        String postData = "method=findTimes&p0={\"request\":\"003\"}";
        performPost(convertToUTF8(postData));
    }

    public static String convertToUTF8(String s) {
        String out = null;
        try {
            out = new String(s.getBytes("UTF-8"), "ISO-8859-1");
        } catch (java.io.UnsupportedEncodingException e) {
            return null;
        }
        return out;
    }

    public void performPost(String encodedData) {
        HttpURLConnection urlc = null;
        OutputStreamWriter out = null;
        DataOutputStream dataout = null;
        BufferedReader in = null;
        try {
            URL url = new URL("http://myserviceurl" + System.nanoTime());
            urlc = (HttpURLConnection) url.openConnection();
            urlc.setRequestMethod("POST");
            urlc.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
            dataout = new DataOutputStream(urlc.getOutputStream());
            // perform POST operation

            dataout.writeBytes(encodedData);
            int responseCode = urlc.getResponseCode();
            in = new BufferedReader(new InputStreamReader(urlc.getInputStream()),8096);
            String response;
            // write html to System.out for debug
            while ((response = in.readLine()) != null) {
                System.out.println(response);
            }
            in.close();
        } catch (ProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (out != null) {
                try {
                    out.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
            if (in != null) {
                try {
                    in.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }

Wykrzacza się na dataout i tu podejrzewam ze jest cos z kodowaniem to UTF8. W C# jak widac wyglada to nieco inaczej. Byłbym wdzieczny za pomoc.
