【问题描述】：
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，我得到了 Jsoup 的简单方法.. 这是我的脚本：
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，它得到了强制关闭。我只是不知道是什么问题。。 我在这里看到教程：http://jsoup.org/cookbook/input/load-document-from-url
Logcat 是这样说的：
