How do I Store Data when changing screen?

Hi all, I am currently building a small app and would like to somehow save the information entered(listpicker, bluetooth connection etc) in the app when changing the screen. When I change the screen to map the data disappears. Sorry for my bad english, im from Switzerland

The simplest option is to use the TinyDB.

Also the documentation -

I dont understand the TinyDB, could you maybe help me do it? Here is my Code

A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook http://www.appinventor.org/book2 ... the links are at the bottom of the Web page. The book 'teaches' users how to program with AI2 blocks.
There is a free programming course here http://www.appinventor.org/content/CourseInABox/Intro and the aia files for the projects in the book are here: http://www.appinventor.org/bookFiles
How to do a lot of basic things with App Inventor are described here: http://www.appinventor.org/content/howDoYou/eventHandling .

Bluetooth connections break when you change screens.

Instead of multiple screens, stack some Vertical Arrangements, and show only one of them at a time.

Sounds good, but how do I do that correctly?
