What's in the source?

For a description of all the projects that make up the Android source code, see Project layout. To see snapshots and histories of the files available in the public Android repositories, visit the GitWeb web interface.

 

The source is approximentely 2.1GB in size.  You will need 6GB free to complete the build.

=> 약 2.1G 정도 필요하고 build 시 6G 정도 필요하답니다.

Setting up your machine

To build the Android source files, you will need to use Linux or Mac OS. Building under Windows is not currently supported.

Linux

The Android build is routinely tested on recent versions of Ubuntu (6.06 and later), but reports of successes or failures on other distributions are welcome.

Ubuntu Linux (32-bit x86)

=> 구글에서도 Ubuntu를 권장 하네요.

To set up your Linux development environment, make sure you have the following:

• Required Packages:
• Git 1.5.4 or newer and the GNU Privacy Guard. 
  

• JDK 5.0, update 12 or higher.  Java 6 is not supported, because of incompatibilities with @Override.
  

• flex, bison, gperf, libsdl-dev, libesd0-dev, libwxgtk2.6-dev (optional), build-essential, zip, curl.  

$ sudo apt-get install git-core gnupg sun-java6-jdk flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev

=> 다운받기 위해서는 Git 이라는 source 관리 tool 이 필요 합니다.

      위 sudo 명령어를 그래도 실행하면 Git 이 설치 됩니다. (만약, proxy를 사용할경우 proxy 설정에서 설정후 하셔야 합니다.)

• You might also want Valgrind, a tool that will help you find memory leaks, stack corruption, array bounds overflows, etc. 

$ sudo apt-get install valgrind

=> 이것도 설치.

• Intrepid (8.10) users may need a newer version of libreadline:

$ sudo apt-get install lib32readline5-dev

=> 8.10 사용시는 일반적으로 설치 되어 있습니다.

Ubuntu Linux (64-bit x86)

=> 여기서는 안해봤습니다. (하지만, 64 가지고 계신분은.. 아래 설명 그대로....)

This has not been as well tested. Please send success or failure reports to repo-discuss@googlegroups.com.

The Android build requires a 32-bit build environment as well as some other tools:

• Required Packages:
• Git, JDK, flex, and the other packages as listed above in the i386 instructions:  
  
• JDK 5.0, update 12 or higher.  Java 6 is not supported, because of incompatibilities with @Override.
• Pieces from the 32-bit cross-building environment
• X11 development
  

$ sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl sun-java5-jdk zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev ia32-libs x11proto-core-dev libx11-dev lib32readline5-dev

• Set the system to use the right version of java by default:
  
  $ sudo update-java-alternatives -s java-1.5.0-sun
  

• X11: Ubuntu doesn't have packages for the X11 libraries, but that can be worked around with the following command:
  
  $ sudo ln -s /usr/lib32/libX11.so.6 /usr/lib32/libX11.so
  
  

Running Linux in a virtual machine

If you are running Linux in a virtual machine, you will need at least 1.5GB of RAM and 10GB or more of disk space in order to build the Android tree.

Other Linux

There's no reason why Android cannot be built on non-Ubuntu systems. Please send any success or failure reports to repo-discuss@googlegroups.com. In general you will need:

• Python 2.4, which you can download from python.org . 
• JDK 5.0, update 12 or higher, which you can download from java.sun.com . Java 6 is not supported, because of incompatibilities with @Override.
• Git 1.5.4 or newer. You can find it at http://git.or.cz/ .

Anything missing from this list? Please let us know!

Mac OS

Requirements:

• To build the Android files in a Mac OS environment, you need an Intel/x86 machine. The Android build system and tools do not support the obsolete PowerPC architecture.
• Android must be built on a case-sensitive file system.
  
• We recommend that you build Android on a partition that has been formatted with the "Case-sensitive Journaled HFS+" file system:
• A case-sensitive file system is required because the sources contain files that differ only in case.
• Journaled systems are more robust. (This is optional, but recommended.)
• HFS+ is required to successfully build Mac OS applications such as the Android Emulator for OS X.
• If you want to avoid partitioning/formatting your hard drive, you can use a case-sensitive disk image instead.
• To create the image:
  
  • launch /Applications/Utilities/Disk Utility
  • select "New Image"
  • size: 8 GB (this will work, but you can choose more if you want to)
  • volume format: case sensitive, journaled
• This will create a .dmg file which, once mounted, acts as a drive with the required formatting for Android development. For a disk image named "android.dmg" stored in your home directory, you can add the following to your ~/.bash_profile to mount the image when you execute "mountAndroid":
  
  
  # command to mount the android file image
  function mountAndroid  { hdiutil attach ~/android.dmg  -mountpoint /Volumes/android; }
  
  
  Once mounted, you'll do all your work in the "android" volume. You can eject it (unmount it) just like you would with an external drive.

To set up your Mac OS development environment, follow these steps:

1. Install the XCode version 2.4 or later from http://developer.apple.com . We recommend version 3.0 or newer.
   
2. Install MacPorts. To do this:
1. Download the tar file from http://www.macports.org/  and untar the files.
2. Run the following: 
     $ ./configure
     $ make
     $ sudo make install
3. Make sure that /opt/local/bin is in your path before /usr/bin. by running
       $ echo $PATH
   If you don't see /opt/local/bin, edit $HOME/.bash_profile and add the line
     export PATH=/opt/local/bin:$PATH
   (or the equivalent for other shells) after any other PATH-related lines. To verify that your path is now correct, open a new terminal and run echo $PATHagain.
4. Ask MacPorts to update itself:
     $ sudo port selfupdate
   
3. Get the following packages from port:
     $ POSIXLY_CORRECT=1 sudo port install gmake libsdl git-core gnupg
4. Upgrade GNU make to 3.81 or later by running.  Mac OS doesn't come with a recent enough version.
     $ sudo ln -s gmake /opt/local/bin/make
   
5. Set an appropriate per-process file descriptor limit. To do this, add the following lines to your .bash_profile file: 
      # set the number of open files to be 1024
      ulimit -S -n 1024

Installing Repo

Repo is a tool that makes it easier to work with Git in the context of Android. For more information about Repo, see Using Repo and Git. 

To install, initialize, and configure Repo, follow these steps:

1. Make sure you have a ~/bin directory in your home directory, and check to be sure that this bin directory is in your path:
     $ cd ~
     $ mkdir bin
     $ echo $PATH 
2. Download the repo script and make sure it is executable:
   $ curl http://android.git.kernel.org/repo >~/bin/repo
   $ chmod a+x ~/bin/repo

      => Git을 사용할때 repo 라는 tool을 이용하여 얻고자 하는 source를 설정해주는것 같습니다.

            위에서 처럼 (1 , 2 번 모두)  모두 실행합니다. 

Initializing a Repo client

1. Create an empty directory to hold your working files: 
   $ mkdir mydroid
   $ cd mydroid
   
2. Run repo init to bring down the latest version of Repo with all its most recent bug fixes. You must specify a URL for the manifest:
   $ repo init -u git://android.git.kernel.org/platform/manifest.git
• If you would like to check out a branch other than "master", specify it with -b, like:
  $ repo init -u git://android.git.kernel.org/platform/manifest.git -b cupcake
  
3. When prompted, configure Repo with your real name and email address. If you plan to submit code, use an email address that is associated with a Google account. 
   

      =>  1,2 번 실행은  repo 를 사용하기 위하여 초기화 설정을 하는것 입니다.

             일반적으로 android 1.0 버전 (현 master)을 사용하지만, cupcake 버전이 필요하신분은 2 번설명처럼

             -b cupcake 를 사용하여 cupcake branch를 얻을수 있습니다.

 

A successful initialization will end with a message such as
   repo initialized in /mydroid

=> 정상적으로 초기화 되면 위와 같은 메시지를 보실 수 있습니다.

Your client directory should now contain a .repo directory where files such as the manifest will be kept. 

What will my name and email be used for?  

To use the Gerrit code-review tool, you will need an email address that is connected with a registered Google account (which does not have to be a Gmail address). Make sure this is a live address at which you can receive messages. The real name that you provide here will show up in attributions for your code submissions.

What is a manifest file?

The Android source files are divided among a number of different repositories. A manifest file contains a mapping of where the files from these repositories will be placed within your working directory when you synchronize your files. 

Getting the files

To pull down files to your working directory from the repositories as specified in the default manifest, run 

   $ repo sync  

=> 이제는 설정한 repo를 가지고 sync를 하면 source를 설정한 폴더에 받기를 시작 합니다.

      (보통 25분 ~ 1시간 정도 소요됩니다. network 속도에 따라....)

For more about repo sync and other Repo commands, see Using Repo and Git.

The Android source files will be located in your working directory under their project names. 

Building the code

To build the files, run make from within your working directory:
    $ cd ~/mydroid  
    $ make

=> 위와 같이 make 명령을 치면 build를 시작합니다.

If your build fails, complaining about a missing "run-java-tool", try setting the ANDROID_JAVA_HOME env var to $JAVA_HOME before making.  E.g.,

    $ export ANDROID_JAVA_HOME=$JAVA_HOME

=> 빌드가 완료되면 out 이라는 폴더가 생성됩니다.

     그중 아래와 같은 파일 3개를 얻을수 있습니다.

   ~mydroid/out/target/product/generic/ramdisk.img

      ~mydroid/out/target/product/generic/system.img

      ~mydroid/out/target/product/generic/userdata.img

이 파일들을 android sdk 의 image 폴더에 복사를 해두면 build 한 버전으로 emulator 를 실행할 수 있습니다.

폴더 경로는 아래와 같습니다.

        android-sdk-windows-1.1_r1/tools/lib/images

Emulator 실행후 이상 없이 실행될 경우 정상적으로 build 되었다고 볼 수 있습니다.
