推荐答案

1. 验证互联网连接性
2. 验证Android SDK工具(工具-> Android-> SDK管理器-> SDK工具选项卡)是否具有"Google Play服务"的最新版本，以及是否未安装该软件包. 然后，如果您使用的是模拟器，请停止模拟器并重新启动它.

1. Verify internet connectivity
2. Verify if the Android SDK tools(Tools -> Android -> SDK manager -> SDK tools tab) has 'Google Play services' latest version and if not install the package. Then if you are using emulator, please stop the emulator and start it again.It works
