No android tv does analog(rca or red yellow white) you would need an adapter

There are HDMI to RCA adapters on Amazon that you can use. I got one for my father's television and hooked a mi box up to it.

Xiaomi mi box has 3.5mm AV output so technically with the right cable it should work, haven't try it myself but I see no reason why it shouldnt work.

Google 3.55mm to Component(or 3.55 to RCA) on amazon,ebay,aliexpress
