Question

I wanted to know how to convert the http response from the server in a proper parsable JSON array

        try {
            HttpClient httpClient = new DefaultHttpClient();
            HttpPost postRequest = new HttpPost(
                    "http://riffre.com/chatapp/search.php?format=json");
            postRequest.setEntity(new UrlEncodedFormEntity(nameValuePair));
            ResponseHandler<String> responseHandler = new BasicResponseHandler();
            responsesrch = httpClient.execute(postRequest, responseHandler);

            Log.v("search response", responsesrch);

this is my code where I post a few parameters in form of name value pairs to the server
and the value of responseserch that I get is

{"users":[{"user":{"city":"gurgaon","username":"zxc","userid":"6","gender":"Male","images":"0"}},{"user":{"city":"gurgaon","username":"tarun","userid":"5","gender":"Male","images":"0"}},{"user":{"city":"gurgaon","username":"vips","userid":"4","gender":"Male","images":"0"}},{"user":{"city":"gurgaon","username":"rah","userid":"3","gender":"Male","images":"0"}},{"user":{"city":"gurgaon","username":"aak","userid":"2","gender":"Male","images":"0"}}]}

and this is in string format ,So I wanted to know how can I convert this string into a json array , I don’t know yet how I must use Input stream and all those entities, Any help therefore would be greatly appreciated.

convert IS to String

 try {
            BufferedReader reader = new BufferedReader(new InputStreamReader(
                    is, "iso-8859-1"), 8);
            StringBuilder sb = new StringBuilder();
            String line = null;
            while ((line = reader.readLine()) != null) {
                sb.append(line + "n");
            }
            is.close();
            json = sb.toString();
        } catch (Exception e) {
            Log.e("Buffer Error", "Error converting result " + e.toString());
        }

convert String to Json Object

try {
            jObj = new JSONObject(json);
        } catch (JSONException e) {
            Log.e("JSON Parser", "Error parsing data " + e.toString());
        }

get Array from Object

 // Getting Array of Contacts
    JSONArray  contacts = json.getJSONArray("users");
