Good morning everyone, after the last updates that the app inventor platform has had, there is an error when starting the app, I show it in the following photo…
Thanks for your reply, I just have chosen this option and it fixed the error, I´d like the app could be sizing fullscreen because it appears middle size and it aligns in the center on the screen,
however, this aport helps me thanks for your support.!
… you can ensure your GUI is full screen on many devices by the way you design it - in particular, position and size components in % rather than pixels.
