如何在Android上使用Cookie发出http请求？

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.CookieHandler;
import java.net.CookieManager;
import java.net.HttpURLConnection;
import java.net.URL;

public class CookieExample {
    public static void main(String[] args) {
        try {
            // 初始化CookieManager
            CookieManager cookieManager = new CookieManager();
            CookieHandler.setDefault(cookieManager);

            // 设置请求URL
            URL url = new URL("https://example.com/login");

            // 创建HttpURLConnection
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
            connection.setRequestMethod("POST");
            connection.setDoOutput(true);

            // 添加请求参数
            String postData = "username=your_username&password=your_password";
            connection.getOutputStream().write(postData.getBytes());

            // 执行请求
            int responseCode = connection.getResponseCode();
            if (responseCode == HttpURLConnection.HTTP_OK) {
                // 读取响应内容
                BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
                String inputLine;
                StringBuffer response = new StringBuffer();

                while ((inputLine = in.readLine()) != null) {
                    response.append(inputLine);
                }
                in.close();

                // 打印响应内容
                System.out.println(response.toString());

                // 设置请求URL
                URL requestUrl = new URL("https://example.com/request");

                // 创建HttpURLConnection
                HttpURLConnection requestConnection = (HttpURLConnection) requestUrl.openConnection();
                requestConnection.setRequestMethod("GET");

                // 执行请求
                int requestResponseCode = requestConnection.getResponseCode();
                if (requestResponseCode == HttpURLConnection.HTTP_OK) {
                    // 读取响应内容
                    BufferedReader requestIn = new BufferedReader(new InputStreamReader(requestConnection.getInputStream()));
                    String requestInputLine;
                    StringBuffer requestResponse = new StringBuffer();

                    while ((requestInputLine = requestIn.readLine()) != null) {
                        requestResponse.append(requestInputLine);
                    }
                    requestIn.close();

                    // 打印响应内容
                    System.out.println(requestResponse.toString());
                }
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
