android – firebase集成错误：Google Play服务已过期

我正在尝试将Firebase集成到我的Android应用程序中.我正在使用这个tutorial.我更新了我的sdk管理器,添加了google-services.json并完成了网站中提到的所有内容.我仍然收到此Google Play服务过时错误.我想获取设备令牌ID,以便我可以在Login Activity中将其发送到服务器.获取设备令牌ID还需要做些什么吗？

解决方法:

我认为这是设备方面的问题.看看你的logcat：

Google Play services out of date. Requires 9256000 but found 9083234

似乎您的设备未运行所需版本的Google Play服务.尝试更新设备上的Google Play服务,这应该可以解决此问题.
