如何在Android Studio中使用Java在应用程序后台执行像HttpURLConnection这样的任务？

public class MyTask extends AsyncTask<Void, Void, String> {
    @Override
    protected String doInBackground(Void... params) {
        try {
            // 创建URL对象
            URL url = new URL("http://example.com/api");

            // 创建HttpURLConnection对象
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();

            // 设置请求方法
            connection.setRequestMethod("GET");

            // 发送请求并获取响应码
            int responseCode = connection.getResponseCode();

            // 处理响应数据
            if (responseCode == HttpURLConnection.HTTP_OK) {
                // 获取响应数据流
                InputStream inputStream = connection.getInputStream();
                BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
                StringBuilder response = new StringBuilder();
                String line;
                while ((line = reader.readLine()) != null) {
                    response.append(line);
                }
                reader.close();
                inputStream.close();

                // 返回响应数据
                return response.toString();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }

    @Override
    protected void onPostExecute(String result) {
        // 在这里更新UI或传递结果
        if (result != null) {
            // 更新UI组件
            textView.setText(result);
        }
    }
}

MyTask task = new MyTask();
task.execute();
