What's the line number of your Activity.LoadLayout("StartLayout") ?

Are you sure you're not using some imageview before loading the layout ?

EDIT: I changed emulator on real device and error don't show, then debugger can show this error...


I found problem, in different sub I use:

Sub Pauza(Czas As Int)

    Dim Czas_koniec As Long = DateTime.Time(DateTime.Now) + Czas 'this line make error!!


    Do While Czas_koniec > DateTime.Time(DateTime.Now)
        DoEvents
    Loop
 
End Sub

now I change properly

Sub Pauza(Czas As Int)

    Dim Czas_koniec As Long = DateTime.Now + Czas


    Do While Czas_koniec > DateTime.Now
        DoEvents
    Loop
   
End Sub

and start working.
Of coz I make mistake but why compiler don't show this error?

You shouldn't hold the main thread in a loop. Nothing good will come out of this.
