Add a screen before screen one

MIT App Inventor Help

Hello,

Is there a way to add a screen before screen one? Beta feedback suggests I add an instruction screen. When I looked it up online, the suggestion was to rebuild the app. Is there an easier way?

There are 2 easy ways …

  1. Use a big notifier in Screen1.Initialize
  2. Add a hidden Vertical Arrangement to Screen1, and make it Visible as needed.

Great idea. Thanks

Yep, try that. That's what we generally refer to as a "Virtual Screen".
You'd need to use the arrangement often for many reasons. One of such reason is, you cannot share various resources between two "actual" screens. When you need to share resources (Such as Database or Timer) between different screens, then you use "virtual screens".
Then you can navigate through the virtual screens by controlling the visibilities of the vertical arrangements.
