windows xp 中cygwin 上载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
