JSoup Android Studio崩溃

我想使用JSoup获取一个Spans值，我没有错误，但我的应用程序只是打开和关闭。如果我不使用，试着抓住

JSoup.connect(url).get()

有如下问题：

“未处理的异常java.io.IOException”

请试试这个

//add Exception to method signature
protected void onCreate(Bundle savedInstanceState) throws IOException {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
  //don't forget to set timeOut like this
    Document doc = Jsoup.connect(url)timeOut(0).get();
    title = doc.title();

//Element span = doc.getElementsByClass("jfg-badge badge-count").get(0);
TextView titleText = (TextView) findViewById(R.id.titletext);
titleText.setText(title);
 }
 }

//add Exception to method signature
protected void onCreate(Bundle savedInstanceState) throws IOException {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
  //don't forget to set timeOut like this
    Document doc = Jsoup.connect(url)timeOut(0).get();
    title = doc.title();

//Element span = doc.getElementsByClass("jfg-badge badge-count").get(0);
TextView titleText = (TextView) findViewById(R.id.titletext);
titleText.setText(title);
 }
 }
