ユーザー名とパスワードを一致させるための次のコードがあります。上記の「応答」は次のようになります -> {"state":"bla bla blaa","re​​ason":"bla bla blaa"}

HttpClient client = new DefaultHttpClient();
                HttpConnectionParams.setConnectionTimeout(client.getParams(), 10000); //Timeout Limit
                HttpResponse response;
                JSONObject json = new JSONObject();
                try{
                    HttpPost post = new HttpPost(URL);
                    post.setHeader("Content-type", "application/json");
                    json.put("username", userName);
                    json.put("password", password);
                    StringEntity se = new StringEntity( json.toString());  
                    Log.v("json_text", json.toString());
                    se.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
                    post.setEntity(se);
                    response = client.execute(post);
                    /*Checking response */
                    if(response!=null){
                        String temp = EntityUtils.toString(response.getEntity()); //Get the data in the entity
                        Log.v("response", temp);
                }}
                catch(Exception e){
                    e.printStackTrace();
                    //createDialog("Error", "Cannot Estabilish Connection");
                }
