Open source

Til að vinna með Android kóða þarf bæði Git og Repo.

Git

Git is an open-source version-control system designed to handle very large projects that are distributed over multiple repositories

Github

project to simplify sharing code, GitHub has grown into an application used by over a million people to store over two million code repositories http://www.slideshare.net/lornajane/git-github-and-open-source

Repo

Repo is a tool that we built on top of Git. Repo helps us manage the many Git repositories, does the uploads to our revision control system, and automates parts of the Android development workflow. Repo is not meant to replace Git, only to make it easier to work with Git in the context of Android. The repo command is an executable Python script that you can put anywhere in your path.
