App Inventor and Multiple Screens


Tribblehunter's Multiple Screen method

Note: The recommended method fo switching screens with App Inventor is the Manager Screen method!

Note from the Colored Dots tutorial:
You can have many screens in an App Inventor app, but a screen always returns to the screen that opened it. On the other hand, you can get the effect of screens switching to arbitrary other screen by setting up a "manager screen" that is used for opening all the other screens. When a screen wants to switch, it returns to the manager with a value saying which screen to open next.

The Tribblehunter method presented here opens another screen and at the same time(!) closes the current screen. Using this method there is no need of a manager screen. With this method, only 1 screen is open the same time. Thank you Tribblehunter for this great solution!

Note: This solution does not work together with the App Inventor 2 Companion app in development mode. You have to build your app to be able to test that.
