Answer 1

public class HttpUtil {

private static final int CONNECT_SUCESS = 200;



public static void sendHttpRequest(final String address,

        final HttpCallBackListener listener) {

    new Thread(new Runnable() {



        @Override

        public void run() {

            HttpURLConnection connection = null;

            try {

                URL url = new URL(address);

                connection = (HttpURLConnection) url.openConnection();

                connection.setRequestMethod("GET");

                connection.setConnectTimeout(3000);

                connection.setReadTimeout(3000);

                connection.setDoOutput(true);

                connection.setDoInput(true);

                StringBuilder response = new StringBuilder();

                int code = connection.getResponseCode();

                if (CONNECT_SUCESS == code) {

                    InputStream in = connection.getInputStream();

                    BufferedReader reader = new BufferedReader(

                            new InputStreamReader(in));

                    String line;

                    while ((line = reader.readLine()) != null) {

                        response.append(line);

                    }

                }

                if (listener != null) {

                    listener.onFinish(response.toString());

                }

            } catch (Exception e) {

                if (listener != null) {

                    listener.onError(e);

                }

            } finally {

                if (connection != null) {

                    connection.disconnect();

                }

            }

        }

    }).start();

}



public interface HttpCallBackListener {

    void onFinish(String response);

    void onError(Exception e);

}

}
