我正在尝试使 Android 'Google Maps Android API v2' 的示例代码正常工作。我得到的项目没有错误。但是，当我尝试运行应用程序时，应用程序立即崩溃。
Java 代码：
package com.example.Bardo;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import com.google.android.gms.maps.SupportMapFragment;
public class GPS extends FragmentActivity{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.gps);
SupportMapFragment fragment = new SupportMapFragment();
fragment.getFragmentManager().beginTransaction().add(android.R.id.content, fragment).commit();
}
}
XML：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".GPS" >
<fragment
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.MapFragment" />
</RelativeLayout>
日志输出：

我用谷歌搜索并没有发现有关此异常的信息。我真的很困惑这个问题，不知道如何解决它。有谁知道如何解决它？谢谢。
