in .net web service

[WebMethod]
public string Android_DDD(string KullaniciKey, string Durum, string PersonelKey)
{
    return EU.EncodeToBase64("{\"Status\":\"OK\",\"R\":[{\"ImzaTipi\":\"Paraf\", \"Personel\":\"Ali Veli üğişçöıÜĞİŞÇÖI\", \"ImzaDurumTipi\":\"Tamam\", \"TamamTar\":\"1.1.2003 11:21\"},{\"ImzaTipi\":\"İmza\", \"Personel\":\"Ali Ak\", \"ImzaDurumTipi\":\"Tamam\", \"TamamTar\":\"2.2.2003 11:21\"}]}");
}

static public string EncodeToBase64(string toEncode)
{
    UTF8Encoding encoding = new UTF8Encoding();
    byte[] bytes = encoding.GetBytes(toEncode);
    string returnValue = System.Convert.ToBase64String(bytes);
    return returnValue;
}

in android

private static String convertStreamToString(InputStream is)
{
    BufferedReader reader = new BufferedReader(new InputStreamReader(is));
    StringBuilder sb = new StringBuilder();
    String line = null;
    try
    {
        while ((line = reader.readLine()) != null)
        {
            sb.append(line + "\n");
        }
    }
    catch (IOException e)
    {
        e.printStackTrace();
    }
    finally
    {
        try
        {
            is.close();
        }
        catch (IOException e)
        {
            e.printStackTrace();
        }
    }
    return sb.toString();
}

private void LoadJsonDataFromASPNET()

                    {
                        JSONObject jsonObject = jsonArray.getJSONObject(i);
                        String ImzaTipi = jsonObject.getString("ImzaTipi");
                        String Personel = jsonObject.getString("Personel");

                        String TamamTar = jsonObject.getString("TamamTar");
                        Toast.makeText(getApplicationContext(), "ImzaTipi:" + ImzaTipi + " Personel:" + Personel + " ImzaDurumTipi:" + ImzaDurumTipi + " TamamTar:" + TamamTar, Toast.LENGTH_LONG).show();

    }
    catch (Exception e)

        e.printStackTrace();
