I'm a novice developer so someone correct me if I'm wrong.
It's a bit of an odd question since android studio is just the IntelliJ IDE with Android components. While Unity is more of an engine/framework that exports the results effortlessly to Android.
If you've never made a game before on Android Studio from scratch, I'd probably recommend starting with a framework/engine like libdx/framework so you wouldn't have to reinvent the wheel.
Both seem to be heavily documented so you'd probably have great support. For a really simple card game though, you might be able to get away with just Android Studio. Really depends how intricate things get.
Might be confusing since I gave opposite advice but for example of the game is like

Then it's definitely doable with just Android Studio. Hopefully that helps.
I did think about it but there already is a chromecast kings cup app that looks pretty sweet so I figured I'd work on games that complement that instead of compete with it.
Here's the link if you want to download the kings cup app: https://play.google.com/store/apps/details?id=com.expandedlabs.kingscupcast&hl=en
King's Cup Cast - King's Cup with the ability to add custom cards or change the rules (I've added a Joker - tell a joke. Anybody who laughs drinks; if nobody laughs drink twice all by yourself. I've also added player specific cards sometimes - for example Karl - Everybody cheers to Karl and take a drink. Karl takes 3 drinks.).
KaraokeCast - not a drinking game, but fun once drunk
Beermaid uses Chromecast, and has a few drinking games (haven't tried this yet, but looks promising)
iPuke (just on the phone - no Chromecast) is kind-of like truth or dare...either do the action on the card or take the number of assigned drinks
Just a tip: I'd suggest starting the night out with one of these, then swap out to something else. Sometimes it gets dull sitting around a phone/TV. If things start getting slow, pull another one out and try it. Maybe your group of friends are different though, who knows.
