获取 android 源代码， 并编译

参考 http://source.android.com/source/download.html

 

首先安装一些基础软件， 直接在ubuntu上安装， 例如git， java

sudo apt-get install git-core gnupg sun-java5-jdk flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev

 

其次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:

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

$ chmod a+x ~/bin/repo

 

 

 

 

第三步，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~/bindirectory in your home directory, and check to be sure that this bin directory is in your path: 
   $ cd ~
   $ mkdir bin 
   $ echo $PATH 
   
2. Download thereposcript and make sure it is executable: 
   $ curl http://android.git.kernel.org/repo >~/bin/repo
   $ chmod a+x ~/bin/repo

 

第四步，Initializing a Repo client 

1. Create an empty directory to hold your working files: 
   $ mkdir mydroid   [空间必须大于10g] 
   $ 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 . 

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

Your client directory should now contain a.repodirectory 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 w hen you synchronize your files.

第五步 Getting the files

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

$ repo sync 

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. 

Verifying Git Tags

Load the following public key into your GnuPG key database.The key is used to sign annotated tags that represent releases. 

$ gpg --import 

then paste the key(s) below, and press Control-D to end the input and process the keys. After importing the keys, you can verify any tag with 

$ git tag -v tagname 

key 9AB10E78: "The Android Open Source [e-mail]"

第六步， Building the code

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

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

Using an IDE

• Using Eclipse for Android platform development 

Troubleshooting

ImportError: No module na med readline 

Mac users getting this should install Python 2.5.2.

Linux users that installed Python from source, make sure the dependencies for libreadline are installed, and rebuild Python.
