Android Question navigation bar

[Uniko Sistemi srl]

Good morning everyone, I have a curiosity that I wanted to ask if it could be done. Is it possible to insert a background (image) in the navigation bar at the bottom?
Thank you I use b4x, but for ios I succeeded

in the navigation bar at the bottom?

No. It is an device-UI you can not change.

The navigation bar can be made semi-transparent but might be tricky to implement in B4A: https://stackoverflow.com/questions/43352842/draw-image-under-android-navigation-bar
