Android Question Firebase SubscribeToTopic Error [Solved]

[Anser]

Hi,

One of my Apps, the source code of which I had not touched for more than a year now is working fine.

Seeing that targetSdkVersion restriction from Google is nearing, today, I just recompiled the app with the latest B4A 8.30

Unfortunately my app is failing at the Firebase SubscribeToTopic(), whereas the Old APK is working fine.

I do not know whether something related to FireBase Messaging has changed during the last one year time or not.

Here is the error that I get when I run my application

** Service (starter) Start **

Any idea, what is causing this error ?

Any help will be appreciated

AS I am using B4A 8.30, as recommended by Erel in the post https://www.b4x.com/android/forum/threads/integrating-firebase-services.67692/ , I changed the Manifest Entries for Firebase as follows.

'Always required when using Google Play Services or Firebase:
'************ Google Play Services Base ************
CreateResourceFromFile(Macro, FirebaseAnalytics.GooglePlayBase)

'Always required when using Firebase:
CreateResourceFromFile(Macro, FirebaseAnalytics.Firebase)

'Always required when using Firebase Notifications / Push messages
CreateResourceFromFile(Macro, FirebaseNotifications.FirebaseNotifications)

Unfortunately, the error is still there

did you refresh the library?

 

[Anser]

Yes. I am using the latest FirebaseNotifications v1.21

 

[DonManfred]

and you also updated the SDK to the newest files?

 

[Anser]

and you also updated the SDK to the newest files?

I updated the repositories from
com.google.firebase:firebase-messaging (Google Maven) 11.8.0
com.google.firebase:firebase-messaging-license (Google Maven) 11.8.0

to
com.google.firebase:firebase-messaging (Google Maven) 17.0.0
com.google.firebase:firebase-messaging-license (Google Maven) 12.0.1

Unfortunately, the same error

 

[DonManfred]

did you updated all recommended items?

 

[Anser]

Yes. I updated all the recommended items.

Now I on the process of installing the latest Android-28
Shall check whether that will eliminate the error and then update this thread regarding the status

Problem solved.

When I logged on to the FireBase Console it asked me to accept their new policies. (I believe t is their new GDPR policy) I accepted it and then my app started working fine. Its very long time since I logged in into the console.
I should have done this first, but never doubted as my old APK was working.

So with that this issue is resolved.
