XDAndroid is based on the Android open-source project (AOSP). AOSP is separated into many individual repositories for Android programs, frameworks and utilities. The AOSP source tree also includes third-party open-source libraries and programs, used by the Android system to perform various tasks. For all of these repositories, a utility called repo manages the logistics of checking out, updating and modifying the sources.
The following documentation is based highly on the standard AOSP source checkout procedures.
Prerequisites
Building an AOSP source tree requires a Linux build environment. Currently, there is a dependency on glibc 2.11 which also requires a recent distribution such as Ubuntu 10.04 or newer (Ubuntu 11.10 may require addtional steps).
In addition, a number of programs and development packages need to be already installed on the build host. Please check that your system has all of the following packages installed. The procedures for installing required packages varies based on the Linux distribution used on the build host.
- Git (revision control system), version 1.5.4 or higher
- Common source-building utilities: automake, GCC, etc. (the build-essential package on Debian/Ubuntu)
- GNU Privacy Guard (gnupg or gpg)
- Java Development Kit (JDK) 6.0 series (Froyo and earlier require Java Development Kit (JDK) 5.0 series, update 12 or higher.)
- flex, a lexical analyzer
- bison, a parser generator
- gperf, a hash function generator
- libsdl and its development files
- esound (libesd0) and its development files
- WxWidgets GTK 2.6 (libwxgtk2.6) and its development files
- zip, a Zip-archive program
- curl, an HTTP (and others) client and library
An example of installing these packages on Ubuntu/Debian:
$ sudo apt-get install git-core build-essential gnupg flex bison gperf libsdl-dev esound zip curl libwxgtk2.6-0 libc6-dev-i386 g++-multilib lib32z1-dev lib32ncurses5-dev java-common openjdk-6-jdk
If multiple versions of Java JREs or JDKs are available, the system must be configured to use JDK-6 by default. On Debian/Ubuntu systems, this can be done via sudo update-java-alternatives -s java-6-openjdk.
If you need Sun's (Oracle's) Java, see here.
As root, create a new file in /etc/apt/sources.list.d/ named hardy.list. Inside the file, add the following two lines:
deb http://us.archive.ubuntu.com/ubuntu/ hardy multiverse
deb http://us.archive.ubuntu.com/ubuntu/ hardy-updates multiverse
These sources may also be added via the user interface program, under System -> Administration -> Software Sources.
After that, update your local packages list and install the package:
$ sudo apt-get update
$ sudo apt-get install sun-java5-jdk
The build host will also need at least 1.5GiB of RAM and 10GiB of disk space for the Android build. The initial checkout of the source tree will require up to 2GiB of disk space.
Installing repo
It is recommended that repo be installed in a normal user's ~/bin directory.
$ mkdir ~/bin
$ curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
$ chmod +x ~/bin/repo
$ PATH=~/bin:$PATH
Initialize repo And Check Out the Source
The XDAndroid project maintains its own manifest for the repo program. This manifest contains a list of all repositories that repo must clone. The XDAndroid manifest directs repo to download variants of certain pieces of AOSP that require modifications for our devices.
The following examples assume you will be checking out the source tree into the directory ~/xdandroid.
$ mkdir ~/xdandroid
$ cd ~/xdandroid
$ repo init -u git://gitorious.org/xdandroid/manifest.git -b gingerbread
$ repo sync
Your tree can be initialized to track a specific branch by adding -b <branch_name> to the end of the repo init command. For example, to grab the froyo source tree, which will then not be forwarded to gingerbread (and any subsequent releases), the following repo init command would be used:
$ repo init -u git://gitorious.org/xdandroid/manifest.git -b froyo
Without a -b <branch_name> argument, the repositories will track the HEAD branch (master for most of the repositories), which will always be the latest released AOSP tree, with live development.
Wait quite a while and your XDAndroid source tree will be checked out. This will download up to 2GiB of data, so it may take a long time depending on your Internet connection's capacity, or traffic to the source repository servers, etc.
After the conclusion of this process, the build tree may be configured. See Build Configuration.
