ActivityNotFoundException（地图活动）

Question

我的应用程序中有一个 MapActivity 。我将它包含在我的清单文件中，但是当我运行应用程序时，除了 MapActivity 之外，一切都运行良好，每当我尝试通过单击按钮启动 MapActivity 时，都会出现以下错误，

您是否使用谷歌插件进行地图活动（对于地图，您应该使用谷歌插件），检查您是否正在使用它。如果您正在使用，请检查您是否有“import com.google.android.maps”行.MapActivity;”在源代码中改为“java.util.Map”，Map 和 MapActivity 都是不同的。您可以发布代码片段以获取更多信息吗？
