android - Google Maps API V2 片段无法膨胀

Question

这是我第一次开发 Android 应用程序，我的第一个目标是让一个简单的地图控件出现在屏幕上。代码和一切看起来都不错，除了应用程序在我的 2.3.7 手机上运行时崩溃！我正在使用 Google API v2 页面中的示例，但它仍然无法正常工作。

我的 Android 手机运行的是 2.3.7 Android 版本。

编码：

<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"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MapActivity" >

<fragment
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.MapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />
</RelativeLayout>

怎么了？
