Kodi needs a third-party PVR-backend to interact with USB TV-tuners and there are no compatible PVR-backends that runs nativly on the Android. It is the same for Xbox One.

For now you either need to get a networked-attached TV-tuner (which can't record) or plugin your USB tuner in a computer on your network and run the PVR-backend on it.

Many people buy a Raspberry Pi to solve this as its a computer that you can plugin your USB tuner and run PVR-backend software on.

Suggest that buy a Raspberry Pi, plugin USB-tuner and try installing LibreELEC on it first

LibreELEC comes preinstalled with some PVR-backend software that is relativly easy to configure, and then you can connect to that PVR-backend from Android over network.
