App Inventor中的多个屏幕组件是什么？

Question

I've been going through App Inventor for Android by Jason Tyler.

He says: " Currently, App Inventor does not support multiple screen components. This is a limitation that many find frustrating ."

So, what I couldn't find anywhere is: "What are multiple screen components."
Could someone give and example, please? Thank you!

Answer 1

You are looking at some old information, most probably for App Inventor Classic.

Multiple screens already have been introduced in 2013, see also the tutorials about multiple screens and The recommended method of switching screens in App Inventor

For current App Inventor 2 tutorials let me recommend you to do the MIT tutorials and the tutorials from appinventor.org
