I tried changing the sdk version and there is still a red underline to it. Can anyone please elaborate what is going on?

    • "red" files in Android Studio means that they aren’t added to git

    • green – just-added files, pending to commit (this is the step you
      should take now)

    • black or white, depend on style – already added to repo files,
      not changed since last commit (also ignored?)

    • blue – these are tracked by repo and changed since last commit

    if you are just messing around and don’t plan to make a repo you can just ignore these colors. repository is strongly recommended for main longer projects
