跑它与谷歌的目标17 API的AVD,它会立即崩溃。
of ran it on an AVD with target Google API 17, it crashes immediately.
推荐答案
我注意到您没有添加对谷歌播放服务保障,谷歌地图API V2需要此运行。
I noticed you have not added protection for Google Play Services, the Google Maps V2 api requires this to run.
可能是由于谷歌的问题上发挥服务不被支持的AVD。尝试在设备上运行。
The issue maybe due to Google Play Services not being supported on AVD. Try running on a device.
也许这可以帮助
