Question

我正在尝试开发一个使用jsoup-1.7.1.jar核心库的Android应用。我将jar文件作为库包含在内，但现在当我想使用它时，我每次都会收到一个SocketTimeoutException。我正在研究Ubuntu 12.04，eclipse-juno构建ID：20120614-1722，模拟器/ avd有100MB的sd，512Ram，并且在API级别16上。

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，但没有找到解决我问题的方法。（包括这一个：How to use AsyncTask for Jsoup Parser?）

是的，我的Manifest.xml中有Internet权限（WebView很棒）
我将代理设置更改为无代理（即使我不相信它是由此造成的，因为在WebView运行之前）。
我试过不同的页面，甚至用普通的IP（所以没有DNS的概率）

也许有明显的误导？提前帮助，非常感谢！

Edit1：根据wireshark发送请求并给出答案： wireshark-cap

Edit2：这很奇怪，有时候它有效，我得到了答案。但是3分钟后，当我再次尝试它时，它不再起作用了。问题是它只能用于10次中的1次。有什么想法吗？

Android - Jsoup - SocketTimeoutException
