Hello my friends,
I use @DonManfred library to authenticate users. Everything was working perfect till today, when i updated recommended sdk updates. Now it throws this error:
B4X: 
User exists=1
Error occurred on line: 431 (Main)
java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String com.google.firebase.iid.FirebaseInstanceId.getToken()' on a null object reference

    at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1183)

Code that throws this error:
B4X: 
    Private fm As FirebaseMessaging
    fm.Initialize("fm")

    Starter.token=fm.Token

If i put a breakpoint at this line of code "Starter.token=fm.Token" it says this: "Error: Cannot run method from watch expression." But even if i put this code to Activity_Start throws again same error. I think that by sdk update something changed and this lib corrupted.
Thank you for your time.

You had problem with it in 2016.
But you are using the old Firebaseauthex library. NOT the firebase UI AUth Library

Yes, but i can not do anything abouit it. I lost the source of the old firebaseauthex library with a hdd crash last year.

That´s the reason i wrote a wrapper for the Firebase UI Auth.

Don one more question, is there any possibility to add fbauth.isInitialised method? Because anytime we use fbauth.initialise it is trying to login automatically... and if i click back button and i re-enter at my app and i try to hit signout button for example, onAuthStateChanged() event is raised plus one time for every button click i did. What i mean, here is the log file after certain clicks:
B4X: 
Clicked:13 Iden:10
onAuthStateChanged()
onAuthStateChanged()
onAuthStateChanged()
onAuthStateChanged()
onAuthStateChanged()
onAuthStateChanged()
onAuthStateChanged()
onAuthStateChanged()
onAuthStateChanged()
onAuthStateChanged()
onAuthStateChanged()
onAuthStateChanged()
onAuthStateChanged()
onAuthStateChanged()
onAuthStateChanged()
** Activity (main) Pause, UserClosed = true **
Memory -----------
Hit=0
Miss=4
Evicted=0
Used=0 bytes
Disk -------------
Used=0 bytes
** Activity (main) Create, isFirst = false **

By the way, what i wrote at post #15 about simultaneously event raises, you can reproduce it at your example but clicking back button(quit app) the renter app and click sign out button. If you do this procedure several times you will see a log file like this.
B4X: 
onAuthStateChanged()
You are logged offf
** Activity (main) Pause, UserClosed = true **
** Activity (main) Create, isFirst = false **
** Activity (main) Resume **
onAuthStateChanged()
onAuthStateChanged()
onAuthStateChanged()
onAuthStateChanged()
onAuthStateChanged()
onAuthStateChanged()
You are logged offf
** Activity (main) Pause, UserClosed = true **
** Activity (main) Create, isFirst = false **
** Activity (main) Resume **
onAuthStateChanged()
onAuthStateChanged()
onAuthStateChanged()
onAuthStateChanged()
onAuthStateChanged()
onAuthStateChanged()
onAuthStateChanged()
You are logged offf
** Activity (main) Pause, UserClosed = true **

I checked firebasenotification with my testapp (lunch break)

After i added some Artifacts manually it does work.

I did not notized the mising ones.

I think they are 3 or 4 missing. Search for
firebase
iid
auth
in the SDK MAnager and make sure you added all available artifacts.

Maybe my SDK log helps to find the missing ones...


firebase-iid-interop-15.0.0
firebase-measurement-connector-15.0.0
firebase-auth-interop-15.0.2

@Erel: If you read this. May i add a request to add the missing Artifacts to the recommended list?
