I want to create an android app, but I also don't want to re-download android studio...

Choices... Choices...

Okay fine. I decided to download it again, I hope I won't regret it.

You could always down load Cordova...

@michelle I can feel your pain 😂 I've been there too!!

Just finished a react native project. It’s pretty awesome!

Just use vs

Try out React native with Expo. You can run the code on your phone, You don't need android studio. And If you need to run it on an emulator, download genymotion.

Just use IntelliJ 🙃

React-Native/Expo if you want stay close to native. Cordova/Ionic/whatever-devrant-uses if you want to use existing web-technologies (html/css/js) to prototype quickly and don't care about what it looks like.
.. or you could bite the bullet (if you planning on using it a decent amount) and just download Android Studio + SDK. You only have to do it once.
