Added backup and restore function

[martusi61]

I've searched quite a bit without finding a save and restore settings feature in the companion app, so I guess you're not there. However, it would be very useful to have it available, especially for the numerous widgets and links that can be created in the latest versions.

The app supports android auto backup which does restore upon reinstalling the application.

L'app supporta il backup automatico di Android che viene ripristinato dopo aver reinstallato l'applicazione.

Very nice, but it didn't work with my tablet. My Teclast M40 broke down, so I bought another new one, when I installed it I chose to restore from Google backup of the old tablet, in fact he restored everything including App companion of which he brought only the URL of the home assistant, all the other settings had been delete.

Perhaps it would also be the case to add a manual import export.
