Android Question FirebaseRemoteConfig Error

SMOOTSARA · Sep 10, 2020

Hello friends

I'm using the FirebaseRemoteConfig 2.52 library and now updating everything from SDK Manager does not work for me anymore.
I get an error when trying to initialize.
It worked properly before the update sdk and B4A ver 10.2 beta

B4X:

(NullPointerException) java.lang.NullPointerException: Attempt to invoke virtual method 'com.google.firebase.remoteconfig.FirebaseRemoteConfig com.google.firebase.remoteconfig.RemoteConfigComponent.getDefault()' on a null object reference

and

B4X:

Hi Erel

Erel · Sep 10, 2020

The manifest should probably be updated. @DonManfred can you write the full list of dependencies? I will use it to extract all the manifests from the AAR files (it is done in the IDE).

i´m not sure about what all is needed with the newest versions.

I tried to update Firebase Manifest snippet from Analytics snippet and the AAR that was generated by Android Studio running the Quickstart Config example.
But that did not work.
I´m not sure how to interpret the error i found in the unfiltered or what is missing :-(

This is the error using my manifestcode in the lib.

The class not found exceptions always appear for services that your app don't use. Ignore them.

Try to add FirebaseNotifications library, and:

CreateResourceFromFile(Macro, FirebaseNotifications.FirebaseNotifications)

it is already in Manifest and Firebase Notifications are used in the app.

Hello DonManfred and Erel
In that case, should we wait for the library update?

SMOOTSARA · Sep 13, 2020

Hello

Will this problem be solved?
Or publish an update without this library?

Thank you good friends

At one day probably yes.
For now i do not have a solution.

SMOOTSARA · Sep 17, 2020

Hi Erel and DonManfred
This library is practical and important
Do you have a plan to solve this problem?
Do you think I should reduce the SDK version to fix this error?
I can start app updates with a lower SDK version of the app.
Thank you for your cooperation.

I use this lib to make A/B Testing and, sadly, don't works with B4A 10.2.
