你好,我正在开发一个Android应用程序,在端口9001上创建一个Web服务器,并提供SD卡请看看我的代码,请帮助我提前感谢这是我的代码即时使用...

代码..

serveropener class

package dolphin.developers.com;

import dolphin.devlopers.com.R;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class serveropener extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.layout3);



    Button button = (Button) findViewById(R.id.Attack);
    button.setOnClickListener(new OnClickListener() {

        public void onClick(View view) {
            // TODO Auto-generated method stub

        Intent  intent1 = new Intent(
                serveropener.this,
         JHTTS.class);
        startActivity(intent1);
