Android::How to Complie Android Source Code

Installing Repo

Repo is a tool that makes it easier to work with Git in the context of Android.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(now ~/Workshop/Android for me):
     $ cd ~/Workshop/Android
     $ mkdir bin
     $ echo $PATH
   
2. Download the repo script and make sure it is executable:
   $ curl >~/Workshop/Android/bin/repo
   $ chmod a+x ~/Workshop/Android/bin/repo

Initializing a Repo client

1. Create an empty directory to hold your working files,cd ~/Workshop/Android:
   $ mkdir djstava
   $ cd djstava
   
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

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

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

   $ repo sync 

Verifying Git TagsLoad 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 Project "

Building the code

To build the files,run make from within your working directory:
    $ cd djstava
    $ make


Note:
Android need java 1.5 supporting,but ONLY java 1.6 in ubuntu karmic's ppa,so remove java 1.6 and download from
sudo apt-get remove java-common

Add executable attri
    chmod +x jdk-1_5_0_21-linux-i586.bin
    ./jdk-1_5_0_21-linux-i586.bin

There will generate a folder jdk1.5.0_21,cp -rf jdk1.5.0_21 /usr/local

    export JAVA_HOME=/usr/local/jdk1.5.0_21
    export JAVA_FONTS=$JAVA_HOME/jre/lib/fonts
    export JRE_HOME=$JAVA_HOME/jre
    export JAVA_PATH=$JAVA_HOME/bin:$JRE_HOME/bin
    export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
    export ANDROID_JAVA_HOME=$JAVA_HOME
    export PATH=$JAVA_PATH:/android/tools:$PATH

And then
    cd djstava
    make
