我正在尝试开发一个使用 jsoup-1.7.1.jar 核心库的 Android 应用程序。我将 jar 文件作为库包含在内，但现在当我想使用它时，我每次都会收到 SocketTimeoutException。我正在使用 Ubuntu 12.04，eclipse-juno Build id：20120614-1722，emulator/avd 有 100MB 的 sd，512Ram 并且在 API 级别 16。

这是我的代码：

public class MainActivity extends Activity {

private EditText text;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    text = (EditText) findViewById(R.id.editText1);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.mainmenue, menu);
    return true;
}

public void onClick(View view) {

    //Yes I'm aware that this should not be done. I'm planing to use it in the AsyncTask
    //doInBackground method, but since it was not working there, I decided to track it
    //down here in the main-activity -> so it's just for debug
    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
    StrictMode.setThreadPolicy(policy);


    Document doc = null;
    String url1 = "http://213.165.64.71";
    String url2 = "http://www.google.com";
    try {
        doc = Jsoup.connect(url2).timeout(10*1000).get();
    } catch (SocketTimeoutException a) {
        Log.e("MyAPP", "Exception----------A!", a);
    } catch (Exception e) {
        Log.e("MyAPP", "Exception----------E!", e);
    }
    String title = doc.title();
    Log.i("MyAPP", "Title="+title);
}
}

错误日志：

是的，我搜索了所有不同类型的帖子，但没有找到任何解决我问题的方法。（包括这一篇：How to use AsyncTask for Jsoup Parser?）

  • 是的，我的 Manifest.xml 中有 Internet 权限（WebView 效果很好）
  • 我将代理设置更改为无代理（即使我不相信它是由它引起的，因为在 WebView 也可以正常工作之前）。
  • 我尝试使用不同的页面，甚至使用普通 IP（所以没有 DNS 的问题）

也许有一些明显的缺失？非常感谢您的帮助，提前谢谢！

Edit1：根据wireshark发送请求并返回答案： 丝鲨帽

Edit2：这真的很奇怪，有时它有效，我得到了答案。但是 3 分钟后，当我再次尝试时，它不再起作用了。问题是它只能工作 10 次中的 1 次。有任何想法吗？
