Android tv on lineage by konstakang.com might be worth looking at. Havent tried it myself but here is a review of android 10 youtu.be/zN3zcUpeW8U?feature=shared which is quite old and I imagine there have been a lot of improvements by now. I might be wrong so anyone feel free to correct: I dont think pi 4 has wifi on android tv only ethernet, but I think pi 5 does have wifi on android plus better graphics drivers.
