Andrew (Digitwell) · May 25, 2018

Hi
I have upgraded one of my development machines to B4A v8.0

I am now havng problems running an app which uses firebase Messaging

NOTE: this code works fine on another machine running v7.8

TargetSDKVersion is 23 (I'm working my way up to 26 !)

The error I have is :
java.lang.NoSuchMethodError: No virtual method subscribeToTopic(Ljava/lang/String

The code in Firebase Messaging is:

B4X:

Public Sub SubscribeTopic(topicName As String)
    Private strg As String = MiscCode.ConvertNametoTopic(topicName) ' Replaces invalid characters with underscore
    fm.SubscribeToTopic(strg) ' Error occurs here
    Log("Subscribing to " & strg)
    topics.Add(strg)
End Sub

and I have upgraded the manifest file to use the Macro snippets.

I have also upgraded the FirebaseAnalytics library to 1.01.

Any Ideas?

I have the same problem since yesterday

Andrew (Digitwell) · May 26, 2018

I have found a temporary fix to this problem.

See my response in https://www.b4x.com/android/forum/threads/error-firebase-with-b4a-v8.93434/

The problem is an update to the firebase libraries which changed the signature of subscribeTopTopic and unsubscribeFromTopic.

Erel · May 27, 2018

Fixed in v1.21: https://www.b4x.com/android/forum/threads/updates-to-internal-libraries.59340/#post-591400

Fixed on a Sunday. This should be an example to all other companies!

Andrew (Digitwell) · May 27, 2018

Great Stuff. Every day is a work day for me as well.

Angel Garcia · Jun 12, 2018

Hi,
I just started using B4A 8.3 and i have this same issue when starting the App, already updated the internal library to FirebaseNotifications 1.21 and still same issue.
My App crashes when it starts. It's important to notice that it was fine with B4A 8.0.
java.lang.NoSuchMethodError: No virtual method subscribeToTopic(Ljava/lang/String

Lcom/google/android/gms/tasks/Task; in class Lcom/google/firebase/messaging/FirebaseMessaging; or its super classes (declaration of 'com.google.firebase.messaging.FirebaseMessaging' appears in blablabla

Am i missing something?
Many thanks in advance!

Andrew (Digitwell) · Jun 12, 2018

Have you updated the Google SDK using the SDK Manager to the latest version?

com.google.firebase:firebase-messaging should be version 17.0.0 or above

Angel Garcia · Jun 12, 2018

Great this got worse,

Andrew (Digitwell) said:
com.google.firebase:firebase-messaging should be version 17.0.0 or above

Just updated as you said and now i got an error of FirebaseAuth:

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

Andrew (Digitwell) · Jun 12, 2018

There is another message which deals with this error:

Erel said:

The issue with Firebase Auth looks like a bug in the latest version of Firebase Auth SDK (firebase-auth 16.0.1). For now you should use the previous version.

Open B4A Sdk Manager folder and find: extras\b4a_remote\installed-components.txt
Open this file, search for com.google.firebase\:firebase-auth=
Change the version to 15.1.0

Angel Garcia · Jun 12, 2018

I'm confused now
I can't find my B4A SDK Manager folder, i was using the old sdkmanager.exe that used the windows interface for updating stuff.
Where is it?

EDIT:
Found it!

Keeps throwing same error, did the correction as Erel said.

I have thi error:

Angel Garcia · Jun 12, 2018

I have this:
Can't even reach the first error

Angel Garcia · Jun 12, 2018

Good news is that i commented the initialization of FirebaseAuth and it seems FirebaseMessaging now works fine.
Still the same issue with FirebaseAuth

Angel Garcia · Jun 12, 2018

Hi All,
Finally solved FirebasAuth extra issue with the help of this post:
https://www.b4x.com/android/forum/t...initialize-with-last-versions-b4a-8-30.93595/

This is a nightmare for me when updating new versions

, anyways i think is part of being a developer.

Thanks all,

Erel · Jun 13, 2018

These issues are not really related to the new B4A version.

firebase-messaging, the Google library, was updated several weeks ago in a binary incompatible way. FirebaseNotifications v1.21 was released to accommodate this change. As this is the latest version it is included with B4A v8.30.

There is an open issue with the latest version of firebase-auth, again the Google library. For now you should use firebase-auth 15.1.0.

Angel Garcia · Jun 14, 2018

Yep,

Did as you said, now works terrific.
Thanks

Hi. I have updated FirebaseNotification library, but still got same error

DonManfred · Jun 14, 2018

You should create a new thread for YOUR issue. The issue here is fixed.
Also use the forumsearch. This is handled a few times now.
