Well too broad a question you are asking..

1) Do a http get request on the URL. (Or using this method) and get the response String, which is JSON. Some examples here

2) See this answer to see how to parse JSON.

simple simple....

String str = "" // your JSON string
JSONObject json = new JSONObject(str);
String apiVersion = json.getString("apiVersion");
 // continue as before for the rest of it...

you Can try below method. you can pass URL and get the Response as result String. public static String result;

public static boolean connect(String url) {
        boolean flag = false;
        HttpClient httpclient = new DefaultHttpClient();

        // Prepare a request object
        HttpGet httppost = new HttpGet(url);
        Log.e("url", url);

        // Execute the request
        HttpResponse response;
        try {

            // https://api.vkontakte.ru/method/audio.search?uid=163398985&q=akoncount=100&access_token=2a4db0e223f0f5ab23f0f5ab5f23da5680223f023f1f5a3c696b018be9b17b9

            response = httpclient.execute(httppost);
            // Examine the response status
            Log.i("vkontake", response.getStatusLine().toString() + "\n"
                    + response);

            // Get hold of the response entity
            HttpEntity entity = response.getEntity();
            // If the response does not enclose an entity, there is no need
            // to worry about connection release

            if (entity != null) {

                // A Simple JSON Response Read
                InputStream instream = entity.getContent();
                Log.d("Jsomn Activity", "---- is --- " + instream);
                result = convertStreamToString(instream);
                Log.d("Jsomn Activity", "---- Result --- " + result);

                // now you have the string representation of the HTML request
                instream.close();

            } else {
                Log.d("Jsomn Activity", "---- is --- null ");
            }
            flag = true;
            net = false;
        } catch (Exception e) {
            Log.d("Jsomn Activity", "---- Catch --- " + e.toString());
            flag = false;
            e.printStackTrace();
        } finally {
            return flag;
        }

    }

There are a couple of ways to do this. One easy way is to define an object structure that matches your data and use http://code.google.com/p/google-gson/ to fill it:

final URL url = new URL("http://yourURL.com");
final InputStream openStream = url.openStream();
final InputStreamReader inputStreamReader = new InputStreamReader(openStream);
final SearchResult searchResult = new Gson().fromJson(inputStreamReader, SearchResult.class);

If your searchResult class containts a field e.g. apiVersion, it will be filled with the data from JSON. Then you have a data field with the other fields inside etc. This is a very easy way to populate your data, but you will have to mirror the structure of the JSON stream in your object model.
