The Android source tree is located in a Git repository hosted by Google. The Git repository includes metadata for the Android source, including changes to the source and when the changes were made. This page describes how to download the source tree for a specific Android code-line.
Sep 20, 2017 By using and examining open source apps, you can learn how to build better apps yourself. The following are my picks for the top open source Android projects. I’ve found these helpful in proving my own ability to ship better production apps.

To start with a factory image for a specific device instead of downloading the source, see Selecting a device build.
Repo is a tool that makes it easier to work with Git in the context of Android. For more information about Repo, see the Repo Command Reference and Repo README.
Repo comes in two parts: One is a launcher script you install, and it communicates with the second part, the full Repo tool included in a source code checkout. To install Repo:
Make sure that you have a bin/
directory in your home directory and that it's included in your path:
Download the Repo Launcher and ensure that it's executable:
Optionally verify the launcher matches our signatures:
If you're using an older system without Python 3.6+, try downloading an older version of the Repo Launcher that still supports Python 2.7. This won't work indefinitely but might help until your system is upgraded.
After installing the Repo Launcher, set up your client to access the Android source repository:
Create an empty directory to hold your working files. If you're using macOS, this has to be on a case-sensitive filesystem. Give it any name you like:
Configure Git with your real name and email address. To use the Gerrit code-review tool, you need an email address that's connected with a registered Google account. Make sure that this is a live address where you can receive messages. The name that you provide here shows up in attributions for your code submissions.
Run repo init
to get the latest version of Repo with its most recent bug fixes. You must specify a URL for the manifest, which specifies where the various repositories included in the Android source are placed within your working directory.
To check out a branch other than master, specify it with -b
. For a list of branches, see Source code tags and builds.
A successful initialization ends with a message stating that Repo is initialized in your working directory. Your client directory should now contain a .repo
directory where files such as the manifest are kept.
To download the Android source tree to your working directory from the repositories as specified in the default manifest, run:
The Android source files are located in your working directory under their project names. To speed syncs, use the -jthreadcount
flag. Also consider adding -qc
to conduct quiet, current branch syncs only. See the Repo Command Reference for more details.
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.
The first step is to create a password with the password generator and follow the instructions on the password generator page.
The second step is to force authenticated access by using the manifest URI https://android.googlesource.com/a/platform/manifest
. Notice how the /a/
directory prefix triggers mandatory authentication. 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 that is then used by Repo:
More rarely, Linux clients experience connectivity issues, getting stuck in the middle of downloads (typically during receiving objects). It's been reported that tweaking the settings of the TCP/IP stack and using non-parallel commands can improve the situation. You need 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, while containing more information.
These instructions assume that the mirror is created in /usr/local/aosp/mirror
. First, create and sync the mirror itself. Notice the --mirror
flag, which you can specify only when creating a new client:
When the mirror is synced, you can create new clients from it. Note that it's important to specify an absolute path:
Finally, to sync a client against the server, sync the mirror against the server, then the client against the mirror:
It's possible to store the mirror on a LAN server and to access it over NFS, SSH, or Git. It's also possible to store it on a removable drive and to pass that drive among users or machines.
Load the following public key into your GnuPG key database. The key is used to sign annotated tags that represent releases.
Copy and paste the key below, then type EOF
(Ctrl-D) to end the input and process the keys.
After importing the keys, you can verify any tag with:
AOSP can't be used from pure source code only and requires additionalhardware-related proprietary libraries to run, such as for hardwaregraphics acceleration. See the sections below for download links and Device binaries for additionalresources.
Some devices package these proprietary binaries on their/vendor
partition.You can download official binaries for the supported devices running taggedAOSP release branches from Google'sdrivers. These binaries add access to additional hardware capabilitieswith non-open source code. To build the AOSP master branch, use theBinaries Preview instead. When building the master branch for a device, usethe binaries for the most recentnumbered release or with the most recent date.
Each set of binaries comes as a self-extracting script in a compressedarchive. Uncompress each archive, run the included self-extracting script fromthe root of the source tree, then confirm you agree to the terms of the enclosedlicense agreement. The binaries and their matching makefiles will be installedin the vendor/
hierarchy of the source tree.
To ensure the newly installed binaries are properly taken into account afterbeing extracted, delete the existing output of any previous build using:
This is “amazing” series of open source projects. See the post published with images: here
This is an extremely competitive list of open source Android apps written in Java. It carefully picks the best Android apps written in Java that are open source. To give you an idea about the quality of this list, the average number of Github stars is 3,874.
The apps are broken down into 13 groups: Social Networking, News, Photos & Videos, Productivity, Music, Game, Messaging, Media, Finance, Architecture, Utilities, Reference, Weather.
Mybridge initially picked the apps. You're welcome to contribute. Let's make sure the quality of app is great.
