Android Question Again error with firebase-auth FirebaseAuth after SDK update

[Alex Guerrero]

Hi, I updated the SDK libraries a few moments ago and I was presented with the following error:

Sub Service_Create
    auth.Initialize("auth") ' <---------- line error
End Sub

*** Service (starter) Create ***
FirebaseAuth initialized
Error occurred on line: 31 (Starter)
java.lang.NullPointerException: Attempt to invoke virtual method 'void com.google.firebase.auth.FirebaseAuth.addAuthStateListener(com.google.firebase.auth.FirebaseAuth$AuthStateListener)' on a null object reference

I am using B4A 8.30 release this week, android-27 and targetSdkVersion = "26".

To continue working, change version 16.0.1 to 15.1.0 in the file installed-components.txt
com.google.firebase\:firebase-auth=15.1.0 <----

There is still an open issue with v16.0.1.

If you don't have v15.1.0 installed then you can find it here: https://www.b4x.com/android/forum/t...ith-last-versions-b4a-8-30.93595/#post-592133
