Getting NPE in FirebaseDatabase.getReference()

Question

I am getting NPE in production build on app start and only once after reinstalling with adb.

Caused by java.lang.NullPointerException
Attempt to invoke interfac         


        

Answer 1

add this to the ProGuard configuration, in order to exclude these classes from obfuscation:

-keep,includedescriptorclasses class com.google.firebase.** { *; }

the fact, that only the release build is being affected hints for this -

different library versions may provide different (library) consumer rules.
