Question

我在Android中遇到了2天的问题.. 我无法从URL解析HTML页面.. 我尝试了很多方法，并且我为简单的方法获得了Jsoup .. 这是我的剧本：

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，当我运行脚本时，它会强制关闭..我只是不知道问题是什么。我在这里看到了教程：http://jsoup.org/cookbook/input/load-document-from-url

这是Logcat所说的：
