我很确定存在 jar 问题。

做以下。

在应用程序层次结构的“根”中创建一个名为“libs”的文件夹（与 src、gen 等一起），并将 jar 文件放在那里。当您清理/构建并重新启动应用程序时，错误应该会消失。

下面是正确的代码。

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();

    }
}
