You can make use of JSONObject to create a simple json like { "Passwd":"String content", "Userme":"String content" } try something like this.

            String json="";
            JSONObject jobj = new JSONObject();
            jobj.put("Userme", "Username");
            jobj.put("Passwd", "PasswordValue");
            json = jobj.toString();

Above String can be sent as one of the parameter using HTTP POST easily. Below function takes url and json as parameters to make POST request.

private void httpPost(String json,String url) throws ClientProtocolException, IOException{
      HttpClient httpClient = new DefaultHttpClient();
      HttpPost httpPost = new HttpPost(url);
      List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>(2);
      nameValuePair.add(new BasicNameValuePair("json", json));
      httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair));
      httpClient.execute(httpPost);
  }
