AOSP Environment Setup

Set up for AOSP development (9.0 or later)

Before you download and build the main branch of the Android source, ensure that your hardware meets the necessary requirements and that required software is properly installed. You should also be familiar with the following terms:

Git

Git is a free and open source distributed version control system. Android uses Git for local operations such as branching, commits, diffs, and edits. For help learning Git, refer to the Git documentation.

Repo

Repo is a Python wrapper around Git that simplifies performing complex operations across multiple Git repositories. Repo doesn't replace Git for all version control operations, it only makes complex Git operations easier to accomplish. Repo uses manifest files to aggregate Git projects into the Android superproject.

Note: It is created by git

Manifest file

A manifest file is an XML file specifying where the various Git projects in the Android source are placed within an AOSP source tree.
