我已按照this page中的教程创建了一个谷歌地图应用程序。除了android目标版本之外，代码与此页面中的代码相同。我已将Google API版本23设置为目标。以下是我的清单。

我提到了解决同一问题的其他一些问题，但与此处提到的不同，我扩展了地图活动，并设置了Google API而不是Android API。我也把地图库放在清单中。我在这做错了什么。请指教。请注意，我在我的模拟器中运行此功能，这也是Google API23。但是我没有做过任何特殊的配置。
下面是logcat输出。

答案 0 :(得分：1)
您正在尝试使用Android版Google地图支持的原始版本（com.google.android.maps）。我们现在称之为地图V1。
这不起作用，因为地图V1已被弃用超过两年。你不能再获得它的API密钥，所以即使你的代码是正确的，它也行不通。崩溃是因为必须在MapView内部使用旧MapActivity，如错误所示。
The current version of Google Maps support for Android - Maps V2 - 具有非常不同的API，不涉及com.google.android.maps包中的类。
