Начало новой деятельности (андроид)

Я пытаюсь запустить новое действие из основного, но я получаю сообщение об ошибке при запуске приложения приложение... неожиданно остановилось. повторите попытку (нет ошибки при затмении). что мой код:

public class clubber extends Activity {
    protected SearchData sData ;
    protected boolean club;
    protected boolean resto;
    protected boolean bar;
    protected String searchTerms;
    protected String city;
    protected String distance;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

       (...)

        //Search button action 
        final Button button = (Button) findViewById(R.id.search);
        button.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                // Perform action on clicks
                Toast.makeText(clubber.this, "Let find something !", Toast.LENGTH_SHORT).show();  
                Intent intent = new Intent();
                intent.setClass(clubber.this, Map.class);
                startActivity(intent);
            }
        });
    }
    (...)
}

целевой класс:

package com.clubber;

import android.os.Bundle;

import com.google.android.maps.MapActivity;
import com.google.android.maps.MapView;

public class Map extends MapActivity {
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.map);
        MapView mapView = (MapView) findViewById(R.id.mapView);
        mapView.setBuiltInZoomControls(true);
    }

    protected boolean isRouteDisplayed() {
        // TODO Auto-generated method stub
        return false;
    }
}
