更新：

在我的 Android SDK 管理器中，我安装了 Android 支持库。在我的 Downloads/android-sdk-macosx/extras/android/support 目录中，我有 v4、v7 和 v13。我将 android-support-v4.jar 复制到 libs 文件夹。右键单击并选择构建路径 > 配置构建路径。在活动布局中，我添加了以下内容（使用 supportmapfragment 而不是 mapfragment）：

<fragment xmlns:android="http://schemas.android.com/apk/res/android" 
  android:id="@+id/map" 
  android:layout_width="match_parent" 
  android:layout_height="match_parent" 
  class="com.google.android.gms.maps.SupportMapFragment"/>

但我仍然收到此错误：

04-16 17:42:00.928: E/AndroidRuntime(363): FATAL EXCEPTION: main 
04-16 17:42:00.928: E/AndroidRuntime(363):

这是完整的跟踪：

API Level 12 之后才支持 MapFragment。建议改用SupportMapFragment。

要使用它，您需要将 Android 支持库包含在您的路径中。按照这些说明将支持库添加到您的项目中。

更新：

此外，Fragment类在 API 级别 11 之前不可用。我相信您的目标是 API 级别 10 的 Gingerbread。这就是您收到以下错误的原因：

Caused by: java.lang.ClassNotFoundException: android.view.fragment in loader dalvik.system.PathClassLoader

看到这个问题，它看起来是一个类似的问题。
