Accuweather android json解析错误

Question

这是我第一次在android中使用json，json正在下载， 我只是得到一个解析错误

API链接到：

http://dataservice.accuweather.com/forecasts/v1/hourly/12hour/83342?apikey=HDJ7qKj9ZH0XEW41vgj507CVox7GrRE8&language=en-us&details=true&metric=true

我在下面添加了一个更好看的JSON示例

这是我的解析代码：

protected JSONObject doInBackground(Pair<String, String>[] pairs) {

    HttpHandler sh = new HttpHandler();
    // Making a request to url and getting response
    String url = "http://dataservice.accuweather.com/forecasts/v1/hourly/12hour/83342?apikey=HDJ7qKj9ZH0XEW41vgj507CVox7GrRE8&language=en-us&details=true&metric=true";
    String jsonStr = sh.makeServiceCall(url);
    System.out.println("Response from url: " + jsonStr);

    if (jsonStr != null) {
        try {

            JSONObject jsonObj = new JSONObject(jsonStr);
            // Getting JSON Array node

            JSONArray getAccuweather = jsonObj.getJSONArray("weather");

            // looping through All Contacts
            for (int i = 0; i < getAccuweather.length(); i++) {

很想知道我的错误，现在已经看了一会儿

编辑：

我在其中一个对象上找到了一个typeMismatch（IconPhrase，第111行），

我加倍检查它不是拼写错误＆amp;输入是一个字符串，而不是int，boolean等。

我还仔细检查了对象的顺序，一切看起来都是有序的。

仍然试图弄清楚

您试图将JSONArray作为String获取。

这是一段代码。希望它有所帮助...
