           JSONObject object = json.getJSONObject(i);
           strData += object.getString("name") + " - " + "\n" + object.getInt("age") + "\n";

Use `HttpURLConnection` or `Volley` for getting response for webpage — ρяσѕρєя K, Aug 26 '16 at 05:11

Use this method.

public String getJSONFromUrl(String url) {
        HttpURLConnection c = null;
        try {
            URL u = new URL(url);
            c = (HttpURLConnection) u.openConnection();
            c.setRequestMethod("GET");
            c.setRequestProperty("Content-length", "0");
            c.setUseCaches(false);
            c.setAllowUserInteraction(false);
            c.setConnectTimeout(5000);
            c.setReadTimeout(5000);
            c.connect();
            int status = c.getResponseCode();
            switch (status) {
                case 200:
                case 201:
                    BufferedReader br = new BufferedReader(new InputStreamReader(c.getInputStream()));
                    StringBuilder sb = new StringBuilder();
                    String line;
                    while ((line = br.readLine()) != null) {
                        sb.append(line).append("\n");
                    }
                    br.close();
                    return sb.toString();
            }
        } catch (IOException ex) {
            Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
        } finally {
            if (c != null) {
                try {
                    c.disconnect();
                } catch (Exception ex) {
                    Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
                }
            }
        }
        return null;
    }
