Obtain string from JSON Object

Question

I have to following response from a server: page:{"result":"ok","id_photo":36782710}.And I'm trying to obtain the result from there by doing this:

String r=page.toString();
JSONArray jArray = new JSONArray(r);
JSONObject jsdata = r.getJSONObject(0);

String result = jsdata.getString("result");
System.out.println("Raspunsul de la server este:" +result);

But I get the following error:

WARN/System.err(30452): org.json.JSONException: Value {"result":"ok","id_photo":36782710} of type org.json.JSONObject cannot be converted to JSONArray

Anyone any idea?

Try instantiating it as a JSONObject instead as the data your a parsing is not an array but a object.

JSONObject json = new JSONObject(response);
String result = json.getString("result");

As madsleejensen said, it should be treated as JSONObject not JSONArray, and for future references, simple advice to differ when to use the right type is: JSONObject is covered by {} and JSONArray covered by [].

+1 Thanks so much for adding this bit of information. I've been pulling my hair out trying to figure out what the problem was. Once I switched to JSONArray - it worked!
