I'm just a noob developer myself, but I believe Android Studio is what most devs use. At least it's what I use and what works for me.

Android Studio is the way to go, especially you're new to this space. Be familiar with the official tools before exploring other options.

Back when I learned I just used the resources from Udacity. Google had created a Kotlin based course with them.

Software wise, it basically came down to Android studio, git, and some bash commands (but mostly for git). But this will be shown in the videos anyway.
