下载android4.4.2源码全过程（附已下载的源码）

今天在下载andriod源码，特来与大家分享一下我的经验。当然，网上教下载源码的教程较多，本文主要针对在GFW下下载源码出现的各种问题的解决方法。

1、首先安装下载客户端git , curl。

命令如下：

sudo apt-get install curl git

2、创建一个bin目录，加入到PATH当中。

mkdir ~/bin
PATH=~/bin:$PATH

3、下载repo的脚本并添加可执行权限。

curl http://git-repo.googlecode.com/files/repo-1.13 > ~/bin/repo
chmod a+x ~/bin/repo

在这里，问题就出来了。自5月底开始，谷歌的相关网站，基本上都已经不能直接访问了，当然，我一直用goagentFQ，所受影响不大，除了打不开tools.android.com这个站点之外。在这里，我假设你已经有代理工具的了（如果没有，会折腾的用goagent，不会折腾的一个月花几块钱买一个）。下面我们就需要设置curl的代理，方法很简单，加个参数 -x 代理地址。比如我的代理服务器为我在局域网里的另一部电脑，IP为192.168.137.1，端口为8087.那么上面下载 repo脚本的命令就应该为：

curl -x 192.168.137.1:8087 http://git-repo.googlecode.com/files/repo-1.13 > ~/bin/repo

下载之后，再修改权限，如上面所示。

4、创建源码目录并进入。

mkdir android4.4.2
cd android4.4.2

5、初始化repo。

repo init -u https://android.googlesource.com/platform/manifest -b android-cts-4.2_r2

在-b后面跟着的是分支名。不出意外，这里问题又来了。googlesource.com站点被墙，所以这里不能直接下载，需要设置代码。这里设置代码很简单，设置一下https.proxy的变量就可以了。如下：

https_proxy=192.168.137.1:8087

后面对应的值记得改回你自己的代理服务器地址及端口。

（补述，http的代理也要设置，后面下载代码会用到，方法同上，设置一下http_proxy变量。）

然后我们再执行初始化。这时，问题又来了，控制台输出：

Get https://code.google.com/p/git-repo/
error: server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none while accessing https://code.google.com/p/git-repo/info/refs
fatal: HTTP request failed

显示是证书问题。导入证书我不知道怎么整，不过我找到了另一种方法，就是取消GIT的SSL验证。命令如下：

export GIT_SSL_NO_VERIFY=1

然后我们再执行初始化，这时成功了（如果网络断开请多试一试）。

6、下载源码。

最后，执行repo sync即可。

7、关于获取源码清单

下面说一下如何获取各个版本的分支名。

首先，没有设置代理的要先设置GIT的代理，如下：

export https_proxy=192.168.137.1:8087
export https_proxy=192.168.137.1:8087
export GIT_SSL_NO_VERIFY=1

其中第一、二行分别是设置http及https的代理服务器，后面的值修改为你自己的代替服务器的地址。

第三行是取消SSL验证，不然会出现SSL验证问题。

然后执行以下命令克隆该git 仓库。

 git clone https://android.googlesource.com/platform/manifest

接着执行git branch -a，即可得到各分支名，如下：

msdx@msdx-ubuntu:~/code/A/manifest$ git branch -a

最后，附上我已经下载好的源码：http://zdz.la/KN8Nai。

我下载的东西，其实有51G左右，其中.repo占了约42G，下载源码请留够硬盘
