Я получаю следующую ошибку принудительного закрытия: java.lang.ClassCastException: com.example.httpgetandroidexample.HttpGetAndroidExample не может быть приведен к android.app
При попытке выполнить следующий код, и я не знаю, почему.
package com.example.httpgetandroidexample;
import java.io.IOException;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;
public class HttpGetAndroidExample {
public static void main(String[] args) {
Document doc;
try {
// need http protocol
doc = Jsoup.connect("http://www.sheriff.org/apps/arrest/results.cfm?lname=smith&fname=").get();
// get page title
String title = doc.title();
System.out.println("Arrest # : " + title);
// get all links
Elements links = doc.select("a[href]");
for (Element link : links) {
// get the value from href attribute
System.out.println("\nlink : " + link.attr("href"));
System.out.println("text : " + link.text());
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
