有人可以告诉我为什么我在启动主要活动时会出现此错误？ 我不明白为什么。 “应用程序进程意外停止了”我在模拟器上有这个 提前谢谢，对不起我的英语，我是法国人。

这是我的代码：

package alpha.omega.alphastreaming;
import java.io.IOException;
import java.util.ArrayList;
import java.util.logging.Level;
import java.util.logging.Logger;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;
import android.app.Activity;
import android.app.ProgressDialog;
import android.os.AsyncTask;
import android.os.Bundle;
import android.widget.TextView;


public class MainActivity extends Activity {

    // URL Address
    String url ="http://seriestreaming.org/";
    ProgressDialog mProgressDialog;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        new Description().execute();


}
    // Description AsyncTask
        private class Description extends AsyncTask<Void, Void, Void> {
            String b;

            @Override
            protected void onPreExecute() {
                super.onPreExecute();
                mProgressDialog = new ProgressDialog(MainActivity.this);
                mProgressDialog.setTitle("Android ");
                mProgressDialog.setMessage("Loading...");
                mProgressDialog.setIndeterminate(false);
                mProgressDialog.show();
            }

            @Override
            protected Void doInBackground(Void... params) {
                int i=0;
                ArrayList<String> a= new Consumer().Start(i);
                 b=a.get(2);
                return null;
            }

            @Override
            protected void onPostExecute(Void result) {
                // Set description into TextView
                TextView txttitle = (TextView) findViewById(R.id.textView3);
                txttitle.setText(b);
                mProgressDialog.dismiss();
            }
        }
    public ArrayList<String>  Start(int i) 
    {
        i = 10;

        return crawl(i);
    }
    private ArrayList<String> crawl(int i) 
    {
        String crawlUrl = this.getCrawlUrl();
        ArrayList<String> titleSerie = new ArrayList<String>();
        try {
            Document doc = Jsoup.connect(crawlUrl).timeout(25000).get();
            Elements hrefs = doc.select("div.movief").select("a[href]");

            for (Element e : hrefs) {
                titleSerie.add(e.text());

            }
            System.out.println(titleSerie.get(i));

        } catch (IOException ex) {
            Logger.getLogger(MainActivity.class.getName()).log(Level.SEVERE, null, ex);
        }
        return titleSerie;
    }
    private String getCrawlUrl() {
        String url = "http://seriestreaming.org/";
        return url;
    }

}

这是logCat：

对不起，我忘记了消费者类：

import java.io.IOException;
import java.util.ArrayList;
import java.util.logging.Level;
import java.util.logging.Logger;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;

public class Consumer {

    public ArrayList<String>  Start(int i) {
        i = 10;

        return crawl(i);
    }

    private ArrayList<String> crawl(int i) {
        String crawlUrl = this.getCrawlUrl();
        ArrayList<String> titleSerie = new ArrayList<String>();
        try {
            Document doc = Jsoup.connect(crawlUrl).timeout(25000).get();
            Elements hrefs = doc.select("div.movief").select("a[href]");

            for (Element e : hrefs) {
                titleSerie.add(e.text());

            }
            System.out.println(titleSerie.get(i));

        } catch (IOException ex) {
            Logger.getLogger(MainActivity.class.getName()).log(Level.SEVERE, null, ex);
        }
        return titleSerie;
    }

    private String getCrawlUrl() {
        String url = "http://seriestreaming.org/";
        return url;
    }
}
