強制關閉時，解析HTML中使用的Android Jsoup

Question

我有問題，請在Android2天.. 我無法從URL解析HTML頁面.. 我嘗試過很多辦法，我也得到Jsoup簡單的方法.. 這是我的腳本：

TextView tv = (TextView) findViewById(R.id.tvv); 

    Document doc; 
    try { 
     doc = Jsoup.connect("http://google.com").get(); 
     String title = doc.title(); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 

但是，它得到了強制關閉，當我運行該腳本..我只是不知道是什麼問題.. 我看到這裏的教程：http://jsoup.org/cookbook/input/load-document-from-url

這裏什麼Logcat說：
