推荐答案

Firebase崩溃版本和 firebase-perf版本必须小于或等于 Firebase-core版本，因此只需在代码中将 Firebase-crash:16.0.1版本更改为Firebase-crash:16.0.0 和 firebase-perf:16.1.0版本为firebase-perf:16.0.0 ，因为您的firebase-core版本为16.0.1

Firebase-crash version and firebase-perf version must be lesser than or equal to the Firebase-core version so In your code just change the Firebase-crash:16.0.1 version to Firebase-crash:16.0.0 and firebase-perf:16.1.0 version to firebase-perf:16.0.0 Because your's firebase-core version is 16.0.1

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