P postasat Active Member Licensed User Longtime User Sep 22, 2018 #3 I have an error in "Activity_resume" when I set a label.text (java.lang.RuntimeException: Object should first be initialized (Label).). I think because layout it's still not loaded/ready. So I would like to know when activity layout is loaded. Thank you. Upvote 0

Semen Matusovskiy Well-Known Member Licensed User Sep 23, 2018 #6 Depends, what to name "ready". For example, LoadLayout does not redraw the screen immediately. From one side - this is a good feature (prevents flickering). But sometimes it's necessary to show a form immediately and to start long process. In this case Screen (0) will be usefull. Another sample - marquee labels. According my investigations jo.RunMethod ("setSelected", Array (True)) in modern API releases wants preceding Sleep (0). Of course, all this is not relative to postasat question. Upvote 0
