安卓开发获取网页源码

在安卓开发中，可以使用 HttpURLConnection 或者 OkHttp 等网络库来获取网页源码。以下是使用 HttpURLConnection 的示例代码：

public String getWebPageSource(String url) {
    HttpURLConnection connection = null;
    BufferedReader reader = null;
    try {
        URL u = new URL(url);
        connection = (HttpURLConnection) u.openConnection();
        connection.setRequestMethod("GET");
        connection.setConnectTimeout(5000);
        connection.setReadTimeout(5000);
        connection.connect();
        if (connection.getResponseCode() == HttpURLConnection.HTTP_OK) {
            InputStream inputStream = connection.getInputStream();
            reader = new BufferedReader(new InputStreamReader(inputStream));
            StringBuilder result = new StringBuilder();
            String line;
            while ((line = reader.readLine()) != null) {
                result.append(line);
            }
            return result.toString();
        } else {
            return null;
        }
    } catch (Exception e) {
        e.printStackTrace();
        return null;
    } finally {
        if (connection != null) {
            connection.disconnect();
        }
        try {
            if (reader != null) {
                reader.close();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

该方法会返回指定网页的源码字符串。
