Answer 1

Firebase-crash版本和firebase-perf版本必须小于或等于Firebase-core版本,因此在您的代码中只需将Firebase-crash:16.0.1版本更改为Firebase-crash:16.0.0和firebase -perf:16.1 .0版本到firebase-perf:16.0.0因为你的firebase -core版本是16.0.1

   compile 'com.google.firebase:firebase-perf:16.0.0'
   compile 'com.google.firebase:firebase-crash:16.0.0'

Answer 2

根据 Firebase 的先决条件文档 - 关于 android 的性能监控文档：

在开始之前，您需要在环境中设置一些内容：

A device running Android 4.0 (Ice Cream Sandwich) or newer, and Google Play services 16.1.0 or higher
The Google Play services SDK from the Google Repository, available in the Android SDK Manager
The latest version of Android Studio, version 2.2 or higher

此链接详细说明了设置。

此外，Alex 提到了我们可以通过升级 gradle 中提到的依赖项来在构建周期中引入最新的 google 服务。

classpath 'com.google.gms:google-services:4.1.0'
