Android Question Firebase auth facebook crash

[Yuri Cinesi]

I'm trying to use the facebook library to add the possibility to log in via facebook using firebase auth, but as soon as I try to run my application it crashes with the following log:

Based on the fact that the error seems to reference the support library I tried to run the jetifier tool to no avail - it didn't even generate a .androidx version of the library.

Any help is appreciated.

The jetifier tool should create a file named: facebook-android-sdk.androidx.aar.

Make sure that the facebook libraries are located in the additional libraries folder and NOT in the internal one.

The newly released update to the library fixed it. Thanks.
