Опитвам се да разработя приложение за Android, което използва основна библиотека jsoup-1.7.1.jar. Включих jar-файла като библиотека, но сега, когато искам да го използвам, ще получавам SocketTimeoutException всеки път. Работя върху Ubuntu 12.04, eclipse-juno Build id: 20120614-1722, емулатор/avd има 100MB SD, 512Ram и е на API-ниво 16.
Ето моят код:
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);
}
}

Да, търсих във всички различни видове публикации и не намерих никакво решение за моя проблем. (включително този: Как да използвам AsyncTask за Jsoup Parser?)
- Да, имам разрешение за интернет в моя Manifest.xml (WebView работи чудесно)
- Промених настройките на прокси на без прокси (въпреки че не вярвам, че е причинено от това, защото преди WebView също работеше).
- Опитах с различни страници и дори с обикновен IP (така че няма проблем с DNS)
Може би нещо очевидно липсва? Помощта наистина се оценява, благодаря предварително!
Edit1: Според wireshark заявката се изпраща и отговорът се връща: 
Edit2: Наистина е странно, понякога работи и получавам отговор. Но 3 минути по-късно, когато го опитам отново, вече не работи. Проблемът е, че работи само ~ 1 от 10 пъти. Някакви идеи?
