We are using:
firebase-ui-auth:3.1.0
firebase-auth:11.4.2
GMS v11.4.2
gms:google-services:3.1.0
This seems to only happen on KitKat (api 19), multiple device manufacturers.

the entire crash information is available here: http://crashes.to/s/dfb96808883

We can't reproduce this, as we could not get our hands on an API19 device, but our guess is that this is an android sdk level incompatibility issue.

@guytavor thanks for the report and the API level information, this is definitely a strange crash and I agree with your initial assessment.

We have the same crash with API 17, 18, 19 after updating to
com.google.firebase:firebase-auth:11.6.2
com.android.support:appcompat-v7:27.0.2

Seeing the same thing on API 19. It is reproduceable in the Android emulator.

This has been fixed and released in 3.1.3.
