Obtain string from JSON Object

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?

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 [].

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");
