Google地图v2未显示

Question

我一直在尝试运行新的Google Maps V2 API的示例项目

并显示一个空白屏幕.

问题是为什么它没有在2.2设备上显示地图,在堆栈跟踪上我看到以下消息:

编辑:好吧,似乎我们还无法在模拟器上运行它.

Answer 1

logcat看到以下消息:

12-06 09:40:36.707: E/Google Maps Android API(14657): Google Maps application is missing.

因此,安装Google地图已解决了这个问题.

此外,似乎谷歌地图安装在某些国家/地区被阻止,如果没有安装谷歌地图,在2.2上运行应用程序将无法运行.

从评论中,用户发布了一个代码,用于检查是否在以下问题中安装了Google地图:

Google Maps Android API V2会检查设备上是否安装了GoogleMaps
