本文主要是介绍The steps for download android source code，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
The steps for download android source code. Except for the git tool, all the other steps is for both Windows and Linux.
以下描述是Windows上的操作步骤，其实windows和Linux上面的执行过程没有多大差别，仅在于git安装、Python脚本改成和机器上Python版本相一致。文档最后给出了Linux上获取代码时，执行的所有命令序列。
1. start git-shell:
2. enter the android folder
3. git clone https://android.googlesource.com/platform/manifest.git
This will create the manifest directory, and clone the ./manifest/.git directory.
hp@HP-PC /e/android
$ git clone https://android.googlesource.com/platform/manifest.git
Cloning into 'manifest'...
remote: Counting objects: 106, done
remote: Finding sources: 100% (106/106)
remote: Total 1030 (delta 144), reused 1030 (delta 144)
Receiving objects: 100% (1030/1030), 895.45 KiB | 498.00 KiB/s, done.
Resolving deltas: 100% (144/144), done.hp@HP-PC /e/android
$4. switch to the manifest directory that just cloned.
And list all the tags by 'git tag'.
hp@HP-PC /e/android
$ ls
a.txt android_src_download_steps.txt download_src_new.py recovery-si
android-si download_src.py manifest srchp@HP-PC /e/android
$ cd manifesthp@HP-PC /e/android/manifest (master)
$ git tag

android-4.3_r3.1
android-4.4.1_r1
android-4.4.2_r1
android-4.4.2_r2
android-4.4_r1
android-4.4_r1.1
android-4.4_r1.2
android-cts-2.2_r8
android-cts-2.3_r10
android-cts-2.3_r11
android-cts-2.3_r12
android-cts-4.0.3_r1
android-cts-4.0.3_r2
android-cts-4.0_r1
android-cts-4.1_r1
android-cts-4.1_r2
android-cts-4.2_r2
android-cts-4.4_r1

android-sdk-4.4.2_r1
android-sdk-adt_r16.0.1
android-sdk-adt_r20
android-sdk-support_r11hp@HP-PC /e/android/manifest (master)
$5. check out the android version
hp@HP-PC /e/android/manifest (master)
$ git checkout android-4.4.2_r2
Note: checking out 'android-4.4.2_r2'.You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:git checkout -b new_branch_nameHEAD is now at 1a5a541... Update manifest for android-4.4.2_r2hp@HP-PC /e/android/manifest ((android-4.4.2_r2))
$6. Understand the manifest/default.xml, and write a python script file
to generate a git-clone file.
Then execute the .py file, or all the git-clone will start automatically.
ATTENTION PLS: a. There must be 40G in the disk. b. All the clone will spend many many hours.
hp@HP-PC /e/android
$ ls
a.txt android_4.4.2_r2 download_src.py recovery-si
android-si android_src_download_steps.txt manifest srchp@HP-PC /e/android

7. here is the python file as the link that I have referenced.

# if the dir does not exist, it will be created autoomatically as below.
rootdir = "E:/android/android_4.4.2_r2"#git program path

root = dom.documentElementprefix = git + " clone http://android.googlesource.com/"

附：Linux上下载Android源码的执行命令：
test@myhost /home/test/Android % git clone https://android.googlesource.com/platform/manifest.git
正克隆到 'manifest'...
