  • .gitignore (Android Studio)

    Each line in a .gitignore file specifies a pattern. When deciding whether to ignore a path, Git normally checks .gitignore patterns from multiple sources… https://git-scm.com/docs/gitignore

    PATTERN FORMAT

    • # – comment
    • foo/ – will match a directory foo
    • !  – negates the pattern
    • /** - matches everything inside.
