Android Question Issue with Firebase Phone Number Authentication Library in B4A 13.40 Beta

[scsjc]

Hi everyone,
I'm currently testing B4A 13.40 Beta and I've encountered an issue using the Firebase Phone Number Authentication library:
https://www.b4x.com/android/forum/threads/firebase-phone-number-authentication.114218/

The authentication does not seem to work properly. Has anyone else experienced the same issue with this library in the latest beta version?
Thanks in advance!

I'm facing the same issue. I've installed all the new required resources with B4A 13.40

Hi Asubias,
I’ve already spoken with Enrico Fuoti, the author of the library. He told me he will review it and adapt it to work with B4A 13.40.

So for now we just need to wait for his update.

Thank you scsjc.

I'm using another library https://www.b4x.com/android/forum/threads/firebase-ui-auth-a-new-dimension-in-authentication.87580 so as both of them are crashing at the same point I guessed that the issue was with some new dependencies added in latest version. I had similar issues in the past and Erel fixed it updating the resources.

Erel, can you confirm if the only solution is to make a new version of the libraries?
