Android Question B4A V12.00 SDK31 Android Version 12 - Pb with StdActionBar V1.52

[imbault]

Hello, I'm having issue with StdActionBar only on Android V 12 (android:targetSdkVersion="31")

On all my other device running Android V 11, it works like a charm...

Any help would be appreciated

Sub Activity_Create(FirstTime As Boolean)
    status.Initialize
    status.put("Réservé(s)","B") 'Booked
    status.put("Encours","P") 'Pending
    status.put("Terminé(s)","C") 'Completed
    status.put("Envoyé(s)","S") 'Sent

    bar.Initialize("bar")
 
    For i=0 To status.Size -1
        bar.AddTab(status.GetKeyAt(i)).Tag=status.GetValueAt(i)
    Next

the Issue seems to be here:

Sub Activity_Resume

    If Forcestatus <> "" Then
        bar.SelectedIndex=0
        Forcestatus =""
    Else
        For i=0 To status.Size -1
            If status.GetValueAt(i)=cMainstatus Then
                Log("status " & status.GetValueAt(i))
                Log("mainstatus " & cMainstatus)
                Log("i " & i)
                Log("bar item " & i)
                bar.SelectedIndex= i
            End If

        Next
     
    End If
    HandleViewRDV
 

End Sub

With this error :

main_activity_resume (java line: 1369)

Thank you

I've tested this on an Android 13 and it works. Does it fail on your device?
BTW, I don't recommend using StdActionBar for new projects. I prefer TabStripViewPager.

Dear Erel,
