Screen(not app inventor's screen, but real smartphone screen) sharing

Hello, I want to create app that sharing a smartphone's screen to another smartphone at using bluetooth.(simply, android to android screen mirroring)

I found screenshot extension by Taifun([]), but it was just about taking screenshot and storing the image.

I couldn't find any extensions about this application.

Please let me know how can I make these things...thank you

This StackOverflow article suggests using bluetooth to do that is not practical. You might search an AndroidStudio forum to see whether a professional compiler can do it.
