Firebase Analytics真正需要哪些API和凭据?

在Firebase控制台中为Firebase Analytics创建应用程序后(如此处所述: https://firebase .google.com/docs/android/setup )在旧版开发者控制台中( https://console.developers .google.com )，我们会自动为相应的项目启用一些API和一些凭据:

After making an app for Firebase Analytics in Firebase Console (as mentioned here: https://firebase.google.com/docs/android/setup) in old developers console (https://console.developers.google.com) for the respective project we get some APIs enabled automatically and some credentials:

API密钥:

1. 服务器密钥(由Google Service自动创建)
2. Android密钥(由Google Service自动创建)

OAuth 2.0客户端ID:

OAuth 2.0 client IDs:

1. xxx.xxx.xxx的Android客户端(由Google服务自动创建)
2. Web客户端(由Google Service自动创建)

还启用了4种API:

1. Google Cloud Messaging
2. 身份工具包API
3. 移动崩溃和效果报告API
4. 令牌服务API.

Firebase Analytics真正需要这些API和凭据中的哪些?我的意思是，如果我仅计划使用Analytic，我们是否需要"Web客户端(由Google Service自动创建)"客户端ID或服务器密钥(由Google Service自动创建)"?

What of these API and Credentials are really needed for Firebase Analytics? I mean, do we need "Web client (auto created by Google Service)" client IDs or "Server key (auto created by Google Service)" if I plan using Analytic only?
