Background

I'm developing an app using Firebase features (Realtime Database, Firebase Messaging, Analytics, Crash Reporting and Auth [Facebook]). In my country, most of the users don't have wifi and rarely upgrade apps (including Google Play Services).

我正在使用Firebase功能开发应用程序（实时数据库，Firebase消息传递，分析，崩溃报告和Auth [Facebook]）。在我的国家/地区，大多数用户没有wifi，很少升级应用（包括Google Play服务）。

Question

As the title suggests, I would like to know the minimum version (the lowest). I'm also willing to remove some features if it will help to lower the Google Play Services version.

正如标题所示，我想知道最低版本（最低版本）。如果它有助于降低Google Play服务版本，我也愿意删除一些功能。
Do I need to check google play service version in my application code or will Firebase check for me?

我是否需要在我的应用程序代码中查看Google Play服务版本，或者Firebase会为我检查？
