Different Version of phone Android: tabbar does not work

Hello everyone, I’m developing an app, which uses the tabbar. On iPhones it works perfectly, while on Android systems I have problems because in the latest Android systems the buttons at the bottom are an integral part of the screen (they are software instead of hardware buttons as in the old ones) and therefore I cannot manage the tabbar buttons. Anyone know how to fix this? Is there a “class” of Android type with usable dimensions? I tried to change the dimensions, but they don’t go. Thanks so much.

(If someone has a useful information on this should hop in.)

I’m not entirely sure about this but remember this being an issue related to AndroidX so this will probably be fixed when AndroidX is done. At the moment, only way around seems to be hiding the buttons. (See)
