Answer 1

我敢肯定有jar問題。

請執行以下操作。

在名爲「libs」的app heirarchy（旁邊是src，gen等）的「根目錄」中創建一個文件夾，並將jar文件放在那裏。當您清理/構建並重新啓動應用程序時，錯誤應該消失。

以下是正確的代碼。

package org.sample; 

import java.io.IOException; 

import org.jsoup.Jsoup; 
import org.jsoup.nodes.Document; 
import org.jsoup.select.Elements; 

import android.app.Activity; 
import android.os.Bundle; 
import android.widget.TextView; 

public class Hello extends Activity { 

    final String BLOG_URL = "http://xjaphx.wordpress.com/"; 
    private String result; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     // set layout view 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 
     getBlogStats(); 

    } 

    protected void getBlogStats() { 
    ((TextView) findViewById(R.id.text)).setText("Please Wait!"); 
     new Thread() { 
      public void run() { 

       Document document; 
       try { 
        document = Jsoup.connect(BLOG_URL).get(); 
        Elements nodeBlogStats = document 
          .select("div#blog-stats ul li"); 

        if (nodeBlogStats.size() > 0) { 
         result = nodeBlogStats.get(0).text(); 
        } 
       } catch (IOException e) { 
        result = "Error"; 
        e.printStackTrace(); 
       } 

       runOnUiThread(new Runnable() { 

        public void run() { 
         ((TextView) findViewById(R.id.text)).setText(result); 
        } 
       }); 

      } 
     }.start(); 

    } 
}
