Hello,

Crash report from Crashlytics-Firebase.
I can not imagine where the mistake is.

Gerät

Ausrichtung: Hochformat
Freier RAM: 17.27 GB
Freier Festplattenspeicher: 39.98 GB

Fatal Exception: java.lang.NullPointerException: Attempt to invoke interface method 'boolean java.util.List.isEmpty()' on a null object reference

B4a-Code:

Sub Service_Create
...
#if Release
   'Log("billmanager Starten")
   InitBillmanager
#end if

End Sub

Public Sub InitBillmanager
    billmanager.Initialize("billmanager", key)

    Wait For billmanager_BillingSupported (Supported As Boolean, Message As String)
    IsBillingSupported = Supported
    If Supported Then
        CallSubDelayed (Main, "GetOwnedProducts")
    End If
End Sub

But I found something here(stackoverflow).

Your code has nothing to do with crash. Device is most likely rooted and doesn't behave like it should, also RAM 17.27 GB ?!

The device doesn't support in-app billing. V1.32 of this library fixes this crash: https://www.b4x.com/android/forum/threads/in-app-billing-v3-library.29998/

My mistake, I still used the old version.
