我对android mapview有点麻烦.每次我尝试打开应用程序时它都会崩溃!码:

package com.jappapps.android.travelbuddy;

import android.os.Bundle;

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

public class TravelBuddy extends MapActivity {
   /** Called when the activity is first created. */
   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.main); // changed to lowercase
       MapView mapView = (MapView) findViewById(R.id.mapview); // match id in main.xml
       mapView.setBuiltInZoomControls(true);
    }

    @Override
    protected boolean isRouteDisplayed() {
        return false;
    }

表现
