Android Framework 批量编译-批量推送 脚本

刚毕业时在某手机厂商任职 Android Framework 研发工程师,工作了一段时间后,深感 Framework 层的编译调试太繁琐,每次都做重复劳动.

因此决定要做一个一揽子解决方案,将整个 编译-打包-安装至手机 的流程用一行命令搞定. 于是写了一年多,写完了这个最终近2000行的脚本.

这是题主从零开始学写 bash 的最初的原因.

现在不再做 Framework 开发了,也再也没哪个脚本写的比这个罗辑更多了.最近整理脚本,觉得不分(xian)享(bai)一下太对不起这脚本了.

需求:

做过 Framework 开发的同学都知道, Framework 层中基本是一个模块一个 Android.mk, 最终的编译生成物有一个的,也有多个的. 编译产物会被放在项目根目录下的固定目录,其路径就对应着这个编译生成物应该推送至手机内的那个路径.

一般的调试流程是: 修改代码 -> 找到模块根目录编译模块 -> 编译 -> 在编译日志中找到编译产物路径 -> 根据编译产物路径将生成物 adb push 到手机

有时一个模块生成多个lib (我记得 installd 会生成7个),少推一个手机就起不来了.

有时一个修改涉及多个模块,那上面的步骤就要重复多次.

我们厂当时代码都放在了服务器上,编译完成后,要把编译生成物放在一个中间服务器(便于审核),再从中间服务器下载到本机,再从本机 push 到手机.那这个流程就又延长且繁琐了,最终每一次编译调试都要五分钟左右,还经常性的出错.

另外系统签名肯定是要放在服务器的,要签名就得上传到签名服务器. 某些模块没有签名的话,直接推也会让手机起不来.

最终要实现的脚本要完成下面事情:

1. 支持指定某个文件为参数,自动找到相应的 Android.mk 编译之

2. 支持指定多个上述文件.多个文件对应一个 Android.mk 时, duplicate 之. 对应多个时,逐个编译之

3. 分析编译日志,找到所有编译产物路径

4. 分析编译产物路径,并用 adb push 逐个将编译产物推送至手机

由于我们厂又多了个中间服务器中转过程,在以上步骤3之后的需求改为如下:

4. 将解析得到的信息汇总,生成 adbpush.sh 的脚本,内含各个编译产物要推送到手机内的路径

5. 将编译产物及 adbpush.sh 打包,并上传至中间服务器

6. 本机编写 adb_auto_push.sh 脚本,从中间服务器下载上一步的压缩包

7. 解压并对需要签名的模块签名(到签名服务器)

8. 执行压缩包内的 adbpush.sh 脚本,将编译产物推送至手机

基于中转服务器,又写了一个脚本,实现轮询中转服务器(每5秒),有新的符合规则的压缩包则下载并推送.这样看起来在服务器转一手看起来就和在本机编译体验一样了.

这个脚本最终完成后,极大的提高了相关工作效率和准确度.

代码:

公司中转服务器的那个脚本就不贴了,这里只贴在本机编译 Framework 并推送的那个脚本.

已经离开Framework相关工作太久,逐一分析太费时间了,这里就偷懒只贴代码了.

这个脚本其实是不限工作环境的,对于现在的 Android 版本,应该稍加修改也还可以用.

#v1.0   compile and push libs to phone
#       $1 should be file or dir you wish to compile
#       without $1 this sh will compile the current dir
#v1.1   add error code for exit
#       1:     pre-compile error
#       2:     adb error
#       3:     post-compile error, most commonly caused by various compile error
#       4:     adb errors, may be caused by "device not found", not critical
#       5:     compile error
#v1.2   add -t option: touch file before compile. the sh will decide which file to touch, usually the last modified file.
#v2.0   2012-03-28
#       add support for multi-dir/file param
#       add -l option: use the given num as "lunch" command param
#v2.1   2012-04-12
#       add support for "choosecombo" when setting up compile environment
#v2.2   2012-04-19
#       add -d option: enable DEBUG
#v2.3   2012-07-03
#       debug: when LocateAndroidmk() return $PROJECT_PATH, exit sh, or it will run "make" in project root dir.

#       1. another way to locate $PROJECT_PATH:
#          run "source build/envsetup.sh", if the return value is 0, than the $PROJECT_ROOT dir is located.
#v3.0   2013-01-17
#       this sh is now independent to environment. changes:
#       1. another way to locate $PROJECT_PATH:
#          just follow "gettop": see if "build/core/envsetup.mk" and "Makefile" exists.
#       2. use getopt to process params.
#       3. change the way of process params to let this shell be less dependent to environment.
#       4. when compile many files, print info after compile even if one of the files failed to compile.
#          this is to ensure that we know which modules has already been compiled.

OPTIONS:
-t : touch the the newest or the given file before compile
-l : use the given number as 'lunch' arg
-d : enable DEBUG, the debug logs will be print
-x : do not push libs to phone after compile
-u : make update-api after compile

DESCRIPTION:
Compile a module based on the given files and dirs, and then push the module(s) to the phone.
By default, the compiled modules will be pushed to the phone.
This shell only compile files or dirs in the same project path.
Note that the options should always come before params.

RETURN CODE:
When things' not all right, this sh will return ERROR CODE as below:
  1:     pre-compile error
  2:     adb error
  3:     post-compile error, most commonly caused by various compile error
  4:     adb errors, may be caused by 'device not found', not critical
  5:     compile error
  6:     input file in different project dir

另: 这个脚本成型于4年前,很多地方处理的并不成熟,

比如找 git 项目根目录的办法

比如 sed 命令的使用

比如 true false 变量的处理

等等等等. 即使是截止到写这篇文章的时间点,题主的bash水平依然有很多不足之处.

说人话就是: 学无止境,欢迎指教,和平讨论~.
