Using

com.google.firebase:firebase-perf:16.2.3
com.google.firebase:firebase-core:16.0.6

and using AndroidX

android.useAndroidX=true
android.enableJetifier=true

Crash with exception on application start. 

 java.lang.NullPointerException: Attempt to invoke virtual method 'boolean com.google.firebase.perf.FirebasePerformance.isPerformanceCollectionEnabled()' on a null object reference

If I disable proguard with minifyEnabled false - it works, but that is not an option.

Updating proguard rules to include

-keep class com.google.firebase.**

fixes the issue.
Also filed a bug report.
