JSoup HTML parse in android

Я пытаюсь создать приложение, которое может подключиться к серверу и заполнить учетные данные для аутентификации (например, доступа к веб-электронной почте). После некоторого поиска я обнаружил, что Jsoup подходит для таких задач. Я искал темы о том, как включить Jsoup в андроид приложения и следовали всем советам там:JSoup HTML parse in android

Скачать файл банку Jsoup
Добавлен банку файл Jsoup в Проект-> свойства-> Java Построить paths-> Libraries-> Добавить внешние баночки
Исправлен экспорт баночки

Вот код:

package com.example.jsoup1; 
import java.io.IOException; 
import android.app.Activity; 
import android.os.Bundle; 
import android.view.Menu; 
import android.widget.Toast; 
import org.jsoup.*; 
import org.jsoup.nodes.Document; 
public class MainActivity extends Activity { 
Document doc; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    try { 

     // need http protocol 
    doc = Jsoup.connect("http://google.com").get(); 

     //get page title 
     String title = doc.title(); 
     Toast.makeText(getBaseContext(),title,Toast.LENGTH_SHORT).show(); 


    } catch (IOException e) { 
     e.printStackTrace(); 
    } 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.main, menu); 
    return true; 
} 

}

Проблема в том, что я получаю сообщение об ошибке после запуска приложения на телефоне. Кажется, что dlavik не может найти какой-то класс, используемый Jsoup, я считаю. Пакет java.awt, как я его пробовал, кажется, не является частью Android-sdk, но каким-то образом он используется Jsoup. Итак, что я могу сделать, чтобы запустить приложение хотя бы?

Вот лог:.

Привет, могу ли я узнать, какую версию JSoup вы используете? – vinaykumar

Привет, я использую Jsoup 1.7.2 jar – n3u3n0

Пожалуйста, обратите внимание на приведенный ниже код, который работает хорошо для меня

class BackGroundTask extends AsyncTask<Void, Void, String> { 

     @Override 
     protected void onPreExecute() { 
      super.onPreExecute(); 
     } 

     @Override 
     protected String doInBackground(Void... params) { 

      try { 
       URL url= new URL("http://www.google.com"); 
       Document doc = Jsoup.connect(url.toString()).get(); 
       String paragaph=doc.title(); 

       return Paragraph; 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } 

      return null; 
     } 

     @Override 
     protected void onPostExecute(String result) { 

      System.out.println(result); 
      super.onPostExecute(result); 
     } 

    }

в вашем OnCreate()

новый BackGroundTask() выполнение ();

У меня такое же поведение. Может быть, из-за некоторых недостающих частей sdk может быть? Я загрузил полную IDE вместе с SDK с страницы загрузки Google – n3u3n0

Не могли бы вы описать, как вы импортировали jsoup jar в проект eclipse android? Я думаю, что секрет лежит там. Я пробовал ответ с других сообщений, но ничего не работало для меня. – n3u3n0

В этом нет ничего скрытого, просто возьмите файл .jar и скопируйте его в папку «libs» вашего проекта, нет необходимости добавлять это путь к классу явно, он будет добавлен автоматически. – vinaykumar
