我使用 Google Maps Android v1 API 创建了我的应用程序的第一个版本。但是现在当我发布我的第二版应用程序时，谷歌地图停止工作。我认为这是因为它已被弃用。

所以现在我正在尝试使用链接创建示例 Android 应用程序以使用 Google Map

https://developers.google.com/maps/documentation/android/start#getting_the_google_maps_android_api_v2

但我低于强制关闭错误

如果您正在为 API 级别 <11 运行代码，请使用FragmentActivity而不是扩展Activity和在 XML 中，使用"com.google.android.gms.maps.SupportMapFragment"

另请检查：Google Maps Fragment does not load

这意味着它没有找到API级别11（Android 3.0.x，HONEYCOMB）中添加的android.view.fragment；您最有可能在 Android 2+ 上构建/运行
