If the kernel version isn't listed in the git log, obtain it from the system image, as described below. To determine the kernel version used in a system image, run the following command against the kernel file:. It's possible to build a boot image using the kernel build environment. To do this you need a ramdisk binary, which you can obtain by downloading a GKI boot image and unpacking it. Any GKI boot image from the associated Android release will work. The target folder is the top-level directory of the kernel tree the current working directory.
If you're developing with AOSP master, you can instead download the ramdisk-recovery. When you have a ramdisk binary and have copied it to gki-ramdisk.

Downloading sources and build tools For recent kernels, use repo to download the sources, toolchain, and build scripts. Find centralized, trusted content and collaborate around the technologies you use most. Connect and share knowledge within a single location that is structured and easy to search. Hey guys I am new to porting android os. I am trying to download android source and wanted to know which git repository should I download for kitkat.
And alos I want to download the source in GIT windows as I do not want to use linux terminal and repo for downloading the source. Note: I have a very limited download limit at high speeds so I only want to download the relevant source files.
No prebuilt Images or and device Images. I just want to download the source for stock kitkat android and use it in ubuntu for further building. I think that you don't understand the organization of the Android source. It is a forest of git repositories, maintained, as CommonsWare says, with a tool called "repo".
Theoretically, you could clone each of the, approximately, git repos, separately. I suspect it would be pretty hard to do. When you download the source, you will get all of the versions, tagged appropriately. You need only checkout at the right tag. You could try github, to download zip files of the branch you require. It also seems to have android kernel files, but you need to search for what you need. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Because using partial clones means that many operations must communicate with the server, use the following if you're a developer and you're using a network with low latency:. For Windows OS only: if you get an error message stating that symbolic links couldn't be created, causing repo init to fail, reference the GitHub Symbolic Links documentation to create these, or to enable their support. For non-administrators, see the Allowing non-administrators to create symbolic links section.
A successful initialization ends with a message stating that Repo is initialized in your working directory. Your client directory now contains a. To download the Android source tree to your working directory from the repositories as specified in the default manifest, run:.
To speed syncs, pass the -c current branch and -j threadcount flags:. The Android source files are downloaded in your working directory under their project names. To suppress output, pass the -q quiet flag. See the Repo Command Reference for all options. By default, access to the Android source code is anonymous. To protect the servers against excessive use, each IP address is associated with a quota. When sharing an IP address with other users for example, when accessing the source repositories from beyond a NAT firewall , the quotas can trigger even for regular use patterns for example, if many users sync new clients from the same IP address within a short period.
In that case, you can use authenticated access, which then uses a separate quota for each user, regardless of the IP address. First, create a password with the password generator and follow the instructions on the password generator page. You can convert an existing client to use mandatory authentication with the following command:.
When downloading from behind a proxy which is common in some corporate environments , you might need to to explicitly specify the proxy for Repo to use:.
More rarely, Linux clients experience connectivity issues, getting stuck in the middle of downloads typically during receiving objects. You must have root access to modify the TCP setting:. When using several clients, especially in situations where bandwidth is scarce, it's better to create a local mirror of the entire server content, and to sync clients from that mirror which requires no network access.
The download for a full mirror is smaller than the download of two clients, and it contains more information.
