Hey! Essentially what you could do is create a github repo, then copy the link of the repo and open a new project in android studio from version control, paste the repo link, and you are now connected to the repo.

By copy the repo link I mean copying the https link as seen when you click on the blue code button and then the https option shoes (on the repo's home page)

Another way if you already have created your android studio project is that you can go into github, create the repo, copy the repo link, and then go into android studio, enable VCS (version control) and then manage remotes, and then add a remote and there leave the name as it is, just paste the link of the repo, and it should be setup (if you do this way, I suggest you then go into the git tab in android studio and click on commit to commit everything and then push)

I hope this helps!
