安卓怎么调用python写的爬虫

public class CrawlerActivity extends AppCompatActivity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);                PythonInterpreter pyint = new PythonInterpreter();        pyint.execfile("sdcard/sl4a/scripts/my_crawler.py");                Object result = pyint.callFunction("fetch_data", "https://example.com");                // 处理从爬虫返回的结果    }}
