Calling list picker to open doesnt work whhen apk is built

when I use companion the button works fine and the listpicker opens, but if i install the app on my phone the button doesnt work and the list picker doesnt open. I tried to open in screen.initialize but it doesnt work too

Screen Initialise would not be the right place.

It's possible that the List is not being populated. A simple test would be to make a static comma-separated list.


If the test works, then there is probably something missing in your Bluetooth setup. Depending on your Android Version, it could be a Permission.

Getting permissions seems to have fixed it, ty! How sure can I be for this to work in older android versions too?
