Note: The source is approximately 2.6GB in size. You will need 10GB free to complete the build.

참고:소스는 대략 2.6GB이다. 너는 10기가 바이트정도가 있어야 빌드까지 할수 있을것이다.

Setting up a Linux build environment

리눅스 빌드화경 세팅하기 

The Android build is routinely tested in house on recent versions of Ubuntu (10.04 and later), but most distributions should

Detailed instructions for Ubuntu 10.04+ follow.

우분투 10.04 이상의 버전을 위한 상세 설명:

Installing the JDK

JDK설치하기 

The Sun JDK is no longer in Ubuntu's main package repository. In order to download it, you need to add the appropriate

repository and indicate to the system which JDK should be used.

추가하는 것이 필요하고  JDK가 사용될 시스템을 예시해라.(? 그냥 아래 명령 치면 되던데; 뭔말인지 모르겠음; ㅋㅋ)

Java 6: for Gingerbread and newer

(여튼;;)Java 6은 진저 브레드 이상에서 사용되어집니다.

(아래 명령을 터미널을 이용해서 치시면 되요~ 오타있으면 이상한 파일 수정해야 하니깐 만들어지니깐 오타 없이 한번에 성공하도록 하세요.)

$ sudo add-apt-repository "deb http://archive.canonical.com/ lucid partner"
$ sudo add-apt-repository "deb-src http://archive.canonical.com/ubuntu lucid partner"
$ sudo apt-get update
$ sudo apt-get install sun-java6-jdk

Java 5: for Froyo and older

Java 5는 프로요 이하 버전에서~

(이 아래에 있는 명령은 프로요 이하 버전에서 치시면 jdk5를 설치 하실 수 있습니다.)

$ sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu dapper main multiverse"
$ sudo add-apt-repository "deb http://archive.ubuntu.com/ubuntu dapper-updates main multiverse"
$ sudo apt-get update
$ sudo apt-get install sun-java5-jdk

Installing required packages

필수 패키지 설치하기 

To set up your development environment, install the following required packages:

당신의 개발 환경을 세팅하기위해, 필수 패키지들을 아래대로 설치하시오:

(또 터미널에서 명령 치시면 됨)

$ sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev libc6-dev 
  lib32ncurses5-dev ia32-libs x11proto-core-dev libx11-dev lib32readline5-dev lib32z-dev

For building Froyo or an older release on a 64-bit system, several other packages are necessary to establish a 32-bit build environment:

64비트 시스템에서 프로요 또는 그 이하버전을 빌드하기 위해서는 32 비트 빌드 환경을 구성하기 위한 몇몇의 다른 패키지들이 추가로 필요하다.

(아래 명령을 치시면 되요.)

$ sudo apt-get install gcc-multilib g++-multilib libc6-i386 libc6-dev-i386


Configuring USB Access

USB 접근 설정하기 

Under GNU/linux systems (and specifically under Ubuntu systems), regular users can't directly access USB devices by default. The system needs to be configured to allow such access.

The recommended approach is to create a file /etc/udev/rules.d/51-android.rules (as the root user) and to copy the following lines in it. must be replaced by the actual username of the user who is authorized to access the phones over USB.

# adb protocol on passion (Nexus One)
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4e12", MODE="0600", OWNER="<username>"
# fastboot protocol on passion (Nexus One)
SUBSYSTEM=="usb", ATTR{idVendor}=="0bb4", ATTR{idProduct}=="0fff", MODE="0600", OWNER="<username>"
# adb protocol on crespo (Nexus S)
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4e22", MODE="0600", OWNER="<username>"
# fastboot protocol on crespo (Nexus S)
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4e20", MODE="0600", OWNER="<username>"

Those new rules take effect the next time a device is plugged in. It might therefore be necessary to unplug the device and plug it back into the computer.

This is known to work on both Ubuntu Hardy Heron (8.04.x LTS) and Lucid Lynx (10.04.x LTS). Other versions of Ubuntu or other variants of GNU/linux might require different configurations.

Setting up a Mac OS X build environment

To build the Android files in a Mac OS environment, you need an Intel/x86 machine running MacOS 10.4 (Tiger), 10.5 (Leopard), or 10.6 (Snow Leopard). The Android build system and tools do not support the obsolete PowerPC architecture.

Android must be built on a case-sensitive file system because the sources contain files that differ only in case. We recommend that you build Android on a partition that has been formatted with the journaled file system HFS+. HFS+ is required to successfully build Mac OS applications such as the Android Emulator for OS X.

Creating a case sensitive disk image

If you want to avoid partitioning/formatting your hard drive, you can use a case-sensitive disk image instead. To create the image, launch Disk Utility and select "New Image". A size of 12 GB should be sufficient to complete the build. Be sure to select "case sensitive, journaled" as the volume format.

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":

# 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.

Installing required packages

• Install XCode from the Apple developer site. We recommend version 3.0 or newer. If you are not already registered as an Apple developer, you will have to create an Apple ID in order to download.

• Install MacPorts from macports.org.

  Note: Make sure that /opt/local/bin appears in your path BEFORE /usr/bin. If not, add

  export PATH=/opt/local/bin:$PATH
  

  to your ~/.bash_profile.

• Get make, git, and GPG packages from MacPorts:

  $ POSIXLY_CORRECT=1 sudo port install gmake libsdl git-core gnupg
  

  If using Mac OS 10.4, also install bison:

  $ POSIXLY_CORRECT=1 sudo port install bison
  

Reverting from make 3.82

There is a bug in gmake 3.82 that prevents android from building. You can install version 3.81 using MacPorts by taking the following steps:

• Edit /opt/local/etc/macports/sources.conf and a line that says

  file:///Users/Shared/dports
  

  above the rsync line. Then create this directory:

  $ mkdir /Users/Shared/dports
  

• In the new dports directory, run

  $ svn co --revision 50980 http://svn.macports.org/repository/macports/trunk/dports/devel/gmake/ devel/gmake/
  

• Create a port index for your new local repository:

  $ portindex /Users/Shared/dports
  

• Finally, install the old version of gmake with

  $ sudo port install gmake @3.81
  

Setting a file descriptor limit

On MacOS the default limit on the number of simultaneous file descriptors open is too low and a highly parallel build process may exceed this limit.

To increase the cap, add the following lines to your ~/.bash_profile:

# set the number of open files to be 1024
ulimit -S -n 1024

Next: Download the source
