Why is my JSONArray being returned as a JSONObject? Or maybe I’m mistaken. I’m trying to parse some data from the JSON located here. I read previous SO questions regarding this topic(such as the question asked Here and what I’ve learned is that it’s important to correctly distinguish between a JSONArray and a JSONObject.
It looks to me like it’s both, more specifically it looks like a JSONArray of JSONObjects, each of which contains name:value pairs. I’m trying to “dig a little deeper to get my data” like the answer suggested, but I’m getting a JSONException at line 96, which is this one. I thought maybe “data” is not the correct name of the array, but the JSON is printed in the LogCat only when I use that string. Any help would be greatly appreciated guys.
Line 96
weatherData = json.getJSONArray(“data”);
I’ve pasted the relevant code below.
public String getWeatherData() {
String url = "http://free.worldweatheronline.com/feed/weather.ashx?q="
+ zipCode
+ "&format=json&num_of_days=5&key=e8570995";
// Create a JSON Parser instance
JSONParser jParser = new JSONParser();
// getting JSON String from URL
JSONObject json = jParser.getJSONFromUrl(url);
// Log.e("WeatherProvider", "Got JSON from URL");
/*
* try { currentCond = json.getString("data"); } catch (JSONException
* e1) { // TODO Auto-generated catch block e1.printStackTrace(); }
*/
try {
// Get array of weather data
weatherData = json.getJSONArray("data");
Log.e("WeatherProvider", "JSONArray is not null");
if (weatherData != null) {
// loop through the data array
for (int i = 0; i < weatherData.length(); i++) {
JSONArray innerJSONArray = weatherData.getJSONArray(i);
JSONObject object = innerJSONArray.getJSONObject(i);
// Store each json item in a variable
currentCond = object.getString("value");
Log.e("WeatherProvider", "current conditin is "
+ currentCond);
}
}
} catch (Exception e) {
e.printStackTrace();
}
return currentCond;
}
}

It isn’t an array, but rather it is a JSON object consisting of an array called weather. This should do the trick:
