How do you setup an app with multiple screens?

Many apps have multiple screens, e.g., a splash screen and the main activity screen of the app. App Inventor provides blocks for swapping between screens and for sharing data between them. The following examples illustrate how to set up such an app.

Example 1. How do you swap between two or more screens?

example 2

You can add a new screen in the Designer by clicking on “Add Screen…” Suppose you named the screen "HomeScreen". Then you can add a button on it called "HomeButton". When you click HomeButton, use the 'open another screen' block to swap to Screen1. You can provide a similar mechanism on Screen1 to swap to HomeScreen.
