windows xp 中cygwin 下载android源码

1. 安装Cygwin。因为repo脚本的运行必须在linux下，因此我们要安装Cygwin。Cygwin是一个在Windows平台下运行的Unix模拟环境，点击这里下载。
2. 安装Cygwin的过程中可以选择要安装的包，以下是我们要安装的包：
   1、Net -> curl；
   2、Devel -> git* (git, git-completion, git-gui, gitk)；
   3、Libs -> libreadline6, libiconv2；
   4、Editors -> vim
   5、Python -> python。

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

4. $ curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > ~/bin/repo
   $ chmod a+x ~/bin/repo
   

   4

5. $ mkdir WORKING_DIRECTORY
   $ cd WORKING_DIRECTORY
   

   $ repo init -u https://android.googlesource.com/platform/manifest
   

   To check out a branch other than "master", specify it with -b:

   $ repo init -u https://android.googlesource.com/platform/manifest -b android-4.0.1_r1
   

6. Getting the files

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

7.  

   $ repo sync
   

 

 

 

按照上面的方法，下载时，可能报连接超时，这是因为，android源码，默认下载是用匿名方式的，google为了某种性能和管理目的，做了限制，像一 般的，动态公网IP就 可能下载不了。为此，google提供了认证方式下载。

 

 

Using authentication

By default, access to the Android source code is anonymous. To protect the servers against excessive usage, each IP address is associated with a quota.

When sharing an IP address with other users (e.g. when accessing the source repositories from beyond a NAT firewall), the quotas can trigger even for regular usage patterns (e.g. if many users sync new clients from the same IP address within a short period).

In that case, it is possible to use authenticated access, which then uses a separate quota for each user, regardless of the IP address.

The first step is to create a password from the password generator and to save it in ~/.netrc according to the instructions on that page.

The second step is to force authenticated access, by using the following manifest URI: https://android.googlesource.com/a/platform/manifest. Notice how the /a/ directory prefix triggers mandatory authentication. You can convert an existing client to use mandatory authentication with the following command:

$ repo init -u https://android.googlesource.com/a/platform/manifest 

也就是，

第一步，去google上产生认证信息，点击上面的"the password generator"

第二步：在cygwin当天用户目录下，新.netrc文件，并把产生的认证信息，填入。

第三步 ：使用此方式，初始化repo:

   $ repo init -u https://android.googlesource.com/a/platform/manifest
第四步:

   repo sync

最终挂机6个多小时，下载完成，给个图片让学友们看看
