JSON and Android. Can't Convert json string to JSONObject

Question

I am trying to convert following json string to JSONObject in android. But it throws JSONException. I have been digging up my mind for past few hours. Please help.

JSON String :

parseExchangeRate({"query":
             {"count":1,"created":"2012-09-07T18:49:32Z","lang":"en-US","results":
                       {"row":{"rate":"55.395","name":"USD to INR"}}}});

Exception:

Value <jsonobject>parseExchangeRate( of type java.lang.String cannot be converted to JSONObject

Code :

String result = convertStreamToString(instream);
Log.d(TAG, result); //this outputs the above stated string
JSONObject json = new JSONObject(result); // this line thows exception

Thanks in advance.

Loose the 'parseExchangeRate()'

what is the JSON string? you state that it's,

parseExchangeRate({"query":
              {"count":1,"created":"2012-09-07T18:49:32Z","lang":"en-US","results":
                        {"row":{"rate":"55.395","name":"USD to INR"}}}});

but that looks like a line of javascript code. JSON != javascript. it looks like your web service is passing back a JSONP response. that's fine, but since you are not a javascript client, you need to parse out the actual JSON string from that response.

String result = convertStreamToString(instream);
Pattern p = Pattern.compile("^.*?\\((.*?)\\);$", Pattern.DOTALL);
Matcher m = p.matcher(result);
if (m.matches()) {
  String json = m.group(1);
  JSONObject jo = new JSONObject(json);
  ...
} else {
  // whoops
}
