Multiple Screens in MIT App Inventor

Hello, many of the apps we make need to have more than one screen, and sometimes it is quite confusing how to share information or values among these screens, so today I share some video tutorials with some good ideas to work with multiple screens in MIT App Inventor, using different approaches. Hope you like them.

A) Basic Tutorial 01 Multiple Screens startValue getValue

This is a very simple tutorial for #AppInventor 2, to pass one value from screen 1 to screen 2.

We use startValue block and get result block and one button. The idea is useful to pass not only one value but multiple using a list. Values that you can pass can be text strings, numbers, colors, variables etc.

6:53 How to pass Multiple Varibles from one screen to other

Sometimes we have a lot of buttons and sliders to modify something in the app and we leave the main app with little space. So a good idea is to use another screen to change settings in the main screen.

This is a very simple tutorial for #AppInventor 2, This tutorial shows how to create apps that have multiple screens. In App Inventor, you can have a screen open a second screen. Later, the second screen can return to the screen that opened it. You can have as many screens as you like, but each screen closes by returning to the screen that opened it. The screens can share information by passing and returning values when they open and close.

We use startValue block and get result block .

Also I showed you how to pass multiple values from one screen to the other. Hope you find it usefull!

C) How to pass values using #TinyDb.

Pass multiple values from Screen1 to Screen2

Hello. In this tutorial I show you a different way to pass multiple values from one screen to another one. I show you how to use TinyDB to pass multiple values.

TinyDb it is a database system for app inventor, and you can save information that can be retrieved in all your app inventor screens. This data is persistent, that means that not matter you close the app, information will be save and ready to be used everytime you use the app. This is very useful and it is not very hard to understand. Hope you find it useful.

Hope you like these tutorials. If you have more ideas about new tutorials please let me know them. I will be happy to share them with you.
