當我打開應用程序時,我收到消息「應用程序停止」。可能是什麼原因?Android JSoup使應用程序崩潰
主類:
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState); // Always call super.onCreate() first.
setContentView(R.layout.activity_main); // Then load the layout.
// Find textView3 in layout and set it's text to HTML code.
// There's no need to create a new TextView() here.
TextView textView = (TextView) findViewById(R.id.textView1);
textView.setText(getHtmlCode());
}
// Structure your code. If it's a larger block that does one thing,
// extract it into a method.
private String getHtmlCode() {
try {
Document doc = Jsoup.connect("http://www.example.com/").get();
Element content = doc.select("a").first();
// return content.text();
return "kktt";
} catch (IOException e) {
Toast.makeText(this, "Failed to load HTML code",
Toast.LENGTH_SHORT).show();
return "kk";
}
}
}
////Elements divs = doc.select("div#test"); //select all the content of the div tags with the id attribute set to test
