Ubuntu 10.10从零开始建立android 2.2 froyo开发环境

为了建立android的开发环境，刚安装了一个Ubuntu 10.10 32-bit，记录下建立android 2.2开发环境的过程和解决的问题。

http://blog.csdn.net/l_serein/article/details/6415861

准备下载环境

参照官方网站准备下载环境

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

准备JDK和Eclipse

froyo最新版的build已经不需要JDK1.5了，直接下载一个linux 32-bit的JDK1.6就行。不太喜欢Ubuntu支持JDK/Eclipse带来的新问题，因此直接下载jdk-6u22-linux-i586.bin并在/opt目录运行安装，为了简单，我把安装后的目录换名jdk1.6。

Eclipse一定要下载Java EE版本，因为ADT插件的build需要。我下载的是3.5.2的Eclipse包eclipse-jee-galileo-SR2-linux-gtk.tar.gz。同样展开在/opt目录，方法就不赘述了。

修改/etc/environment并重新登录：

$ sudo ln -s /opt/eclipse/eclipse /usr/bin/eclipse
$ sudo vi /etc/environment
PATH
=
"/opt/jdk1.6/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"
JAVA_HOME
=/opt/jdk1.6
JAVA_BIN
=/opt/jdk1.6/bin
CLASSPATH
=/opt/jdk1.6/lib/dt.jar:/opt/jdk1.6/lib/tools.jar
ECLIPSE_HOME
=/opt/eclipse

下载Android源码

按照官方网页http://source.android.com/source/download.html指导下载Android源码，也不赘述。

$ sudo curl http://android.git.kernel.org/repo 
>
/bin/repo
$ sudo chmod a+x /bin/repo

我是在/work文件系统中建立android下载目录的，注意这里最好有10GB以上剩余空间。 

$ sudo mkdir /work/android
$ sudo chown carl /work/android
$ cd /work/android
$ repo init -u git://android.git.kernel.org/platform/manifest.git
$ repo sync

编译Android SDK

Android 2.2源码直接支持JDK1.6和64-bit Linux，反而32-bit Linux还需要手工修改一些文件。错误如下

Only 64-bit build environments are supported beyond froyo/2.2.

修改方法具体请参阅

编译SDK并配置环境

如下就是编译SDK

$ cd /
work
/android
$ make sdk

编译完后会在out/host/linux-x86/sdk目录下生成一个zip文件，我的是android-sdk_eng.carl_linux-x86.zip。展开到/opt目录下并配置环境 

$ sudo unzip -e /work/android/out/host/linux-x86/sdk/android-sdk_eng.carl_linux-x86.zip
$ sudo chown -R carl  android-sdk_eng.carl_linux-x86/
$ sudo vi /etc/environment
PATH
=
"/opt/android-sdk_eng.carl_linux-x86/tools:/opt/sdk/android-sdk_eng.carl_linux-x86/platform-tools:/opt/jdk1.6/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"

 重新登录下。

编译ADT

我下载的android 2.2源码中有个问题，编译ADT插件的时候会出错，修改sdk/eclipse/scripts目录下的build_plugins.sh即可。原来的CONFIG_DIR目录会/work/android并列目录下生成out，产生权限问题。

$ vi /
work
/android/sdk/eclipse/scripts/build_plugins.sh
...
CONFIG_DIR="../../out/eclipse-configuration-$BUILD_VERSION"
...

如下可以编译Eclipse插件

$ mkdir ~/adt
$ cd /work
/android/sdk/eclipse/scripts
$ ./build_server.sh ~/adt

在~/adt目录下生成了Eclipse插件包android-eclipse-v201011020546.zip。

安装Eclipse插件

Help->Install New Software选取Archive...参见下图安装Eclipse插件(添加链接)

https://dl-ssl.google.com/android/eclipse/

至此Android编译开发环境全部完成。
