我试图在 Android 中测试 Google Maps API。但是在编译过程中我收到了这个错误：

我在 StackOverflow 上进行了搜索，但我认为我的代码中可能没有任何问题。我是否需要针对 Google API 或 SDK 进行编译？

你的问题是这样的：

Caused by: java.lang.NoClassDefFoundError: com.google.android.gms.maps.model.LatLng

Latlng基本找不到类包。Latlng是google-play-services图书馆的一部分，这意味着你对谷歌的包有某种引用问题。

检查我写的本指南的第 1-3 步，将 Google 地图添加到您的应用程序以供google-play-service图书馆参考：

谷歌地图 API V2
