Android Question Android 9 B4XLoadingIndicator

[Almora]

hi..
I'm using video viewing.
error occurs when I rotate the screen in android 9.
works well on android 6, 7, 8.

I'm using this code to rotate the screen.

........

Sub vv_Prepared
 
    Label1.Visible=False

    For Each v As View In Activity.GetAllViewsRecursive
        If v.Tag Is B4XLoadingIndicator And v.Visible = True Then
            Dim x As B4XLoadingIndicator = v.Tag
            x.Hide
        End If
    Next
 
End Sub


Sub VV_Error(what As Int, iextra As Int)
    Msgbox("error","")
    For Each v As View In Activity.GetAllViewsRecursive
        If v.Tag Is B4XLoadingIndicator And v.Visible = True Then
            Dim x As B4XLoadingIndicator = v.Tag
            x.Hide
        End If
    Next
    Label1.Visible=False
    vv.Pause
'    Activity.Finish
'    StartActivity(page2)
End Sub


Sub Button1_Click
   p.SetScreenOrientation(0)
End Sub

1. Never use Msgbox.
2. Check your layout and make sure that the view size in all orientations is larger than zero.
