JSON无法从PHP的int值 [英] JSON can't get Int value from php

问题描述

我的问题很简单。我不能让项目从PHP和值在我的Andr​​oid应用程序崩溃。我的PHP：

My problem is simple. I can't get the value of item from php and my android app crashes. My PHP:

<?php
$control["value"] = 0;
echo json_encode($control);
?>

我的Java的Andr​​oid：

My Java Android:

private static final String CONTROL_URL = "xxxxx.controller.php";
int control;

...

@Override
public void onClick(View v) {
    JSONParser jParser = new JSONParser();
    //it crash here
    JSONObject json = jParser.getJSONFromUrl(CONTROL_URL);

    try {
          control = json.getInt(CONTROL_URL);

    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        }

        if (control == 0) {
                   //Do something...
            }

当我试图去上我的浏览器的PHP文件它显示我：{值：0}。因此，能不能有人帮我解决这个问题？顺便说一句，我的网址 - xxxxx.controller.php是不是真实的，我用一个真实的我的应用程序，但我不想表现出来。

When i tried to go to my php file on browser it shows me: {"value":0} . So could someone help me solve this problem? By the way, my url - xxxxx.controller.php isn't real, I use a real one for my app, but I don't want to show it.

推荐答案

错误日志显示你正在主线程（NetworkOnMainThreadException），它的Andr​​oid禁止在网络电话。您将有移动电话获取的JSON到一个单独的线程。使用一个异步任务会做到这一点。

your error log shows that you are making a network call on the main thread (NetworkOnMainThreadException), which android prohibits. You will have to move the call for getting the JSON to a separate thread. Using an Async Task will accomplish this.
