Mapview示例在启动时崩溃

我正在尝试mapview示例。但它在推出活动时会崩溃。我的构建目标是版本2.1的Google API。它在设备和仿真器上都崩溃了。另外，我不能Override方法isRouteDisplayed。这里是我的代码Mapview示例在启动时崩溃

package com.sandy.hellogooglemaps; 

import android.app.Activity; 
import android.os.Bundle; 

import com.google.android.maps.MapView; 

public class HelloGoogleMaps extends Activity { 

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main);   
     MapView mapView = (MapView) findViewById(R.id.mapview); 
     mapView.setBuiltInZoomControls(true); 
    }  

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

}

和我的清单文件是

<application android:icon="@drawable/icon" 
android:theme="@android:style/Theme.NoTitleBar" 
android:label="@string/app_name"> 
    <activity android:name=".HelloGoogleMaps" 
       android:label="@string/app_name"> 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 
      <category android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity> 
    <uses-library android:name="com.google.android.maps" /> 
</application> 
<uses-permission android:name="android.permission.INTERNET" />

我的布局XML是

具体使用哪模拟器？以Google API或普通目标为目标创建。 – sudmong 2011-05-28 11:07:17
