Try this one, working for me 


    DefaultHttpClient httpclient = new DefaultHttpClient(); 
     HttpPost request = new HttpPost(Url); 
     StringEntity se = new StringEntity(JSONobject.toString(), "UTF-8"); 
     se.setContentType("application/json;charset=UTF-8"); 
     se.setContentEncoding(new BasicHeader(HTTP.CONTENT_TYPE, 
       "application/json;charset=UTF-8")); 
     request.setEntity(se); 
     HttpResponse httpresponse = httpclient.execute(request); 
     HttpEntity resultentity = httpresponse.getEntity(); 
     InputStream inputstream = resultentity.getContent(); 
     result = convertStreamToString(inputstream); 


    private static String convertStreamToString(InputStream inputstream) { 
    // TODO Auto-generated method stub 
    String line = ""; 
    StringBuilder total = new StringBuilder(); 
    BufferedReader rd = new BufferedReader(new InputStreamReader(
      inputstream)); 
    try { 
     while ((line = rd.readLine()) != null) { 
      total.append(line); 
     } 
    } catch (Exception e) { 
    } 
    return total.toString(); 
}
