I have a B4X app that receives Firebase Notifications.
When the app is running, I receive FB Notifications with no problem.
However, if the app is running in the Background, I receive the following error:
B4X: 
** Activity (splash) Pause event (activity is not paused). **
B4XPage_Background
** Activity (splash) Resume **
B4XPage_Foreground
** Activity (splash) Pause event (activity is not paused). **
B4XPage_Background
java.lang.IllegalArgumentException: com.ecowatch.AVPsecure: Targeting S+ (version 31 and above) requires that one of FLAG_IMMUTABLE or FLAG_MUTABLE be specified when creating a PendingIntent.
Strongly consider using FLAG_IMMUTABLE, only use FLAG_MUTABLE if some functionality depends on the PendingIntent being mutable, e.g. if it needs to be used with inline replies or bubbles.

I don't understand the use of "FLAG_IMMUTABLE" / "FLAG_MUTABLE" or where is is required/set in the code.

are you sure to use B4A 13 with an updated SDK?
Did you change FirebaseMessaging Service to a FilebaseMessaging Receiver?

Check the Tutorial

[B4X] Firebase Push Notifications 2023+

Google has deprecated the previous method of sending push notifications. It will stop working on June 2024. If you have an already working solution then you only need to update the B4J side. Do make sure that you switched from the service to a receiver on B4A. The new API is (confusingly) named...

Yes, B4A 13.00
I have a number of apps that use the FB notifications and it is my understanding that nothing on the B4A had to be changed, only on the B4J side that pushes the FB notification.

Yes, all requirement have been met.
Notifications are received when the app is running, but not when app is in the background.

From the error, I guess this problem only happened in Android 12+ (API 31).
