parsing URL in String from JSON

Question

1) I've got a JSON file:

{
  "serverURI":"http://localhost:8080/PocketUNI_API/serverURLs",
  "newsURI":"http://localhost:8080/gateway/rss/rss.xml",
  "modulesURI":"http://localhost:8080/PocketUNI_API/modules"
}

2) I need to get URLs on Java client in String format.

String json = jsonReceiver.makeHttpRequest(URL_SERVER, "GET", params);
JSONArray uris = new JSONArray(json);

Receiver works fine and json shows the correct string received, but when it goes to parsing with JSONArray it throws an error

org.json.JSONException: Value {"serverURI":"http:\/\/192.168.0.... of type org.json.JSONObject cannot be converted to JSONArray.

Question: How to parse json with URL values?

to loop through the multiple json objects using jsonArray object — exomen, Apr 09 '13 at 14:20
the code you posted above dosnt seems to have an array of jsonobject instead it has a single json object and casting obejct to array will give u jsonexception try to extract a single object — Vivek Bajpai, Apr 09 '13 at 14:23
not `JSONArray` but `JSONObject`. JSONObject json = new JSONObject(str) — lichengwu, Apr 09 '13 at 14:30

You don't get a JSONArray but a JSONObject.

JSONObject uris = new JSONObject(json);

json is a json object not an array, that is why you are getting the error. An array will be wrapped with in [ and ], and objects within { and }.

JSONObject uris = new JSONObject (json);

Instead of JSONArray you must use JSONObject.

JSONObject uris = new JSONObject(json);

In your code just replace JSONArray to JSONobject

JSONObject uris = new JSONObject(json);
