Android Framework 批量編譯-批量推送腳本

剛畢業時在某手機廠商任職 Android Framework 研發工程師,工作了一段時間後,深感 Framework 層的編譯調試太繁瑣,每次都做重複勞動.

因此決定要做一個一攬子解決方案,將整個編譯-打包-安裝至手機的流程用一行命令搞定. 於是寫了一年多,寫完了這個最終近2000行的腳本.

這是題主從零開始學寫 bash 的最初的原因.

現在不再做 Framework 開發了,也再也沒哪個腳本寫的比這個羅輯更多了.最近整理腳本,覺得不分(xian)享(bai)一下太對不起這腳本了.

需求:

做過 Framework 開發的同學都知道, Framework 層中基本是一個模塊一個 Android.mk, 最終的編譯生成物有一個的,也有多個的. 編譯產物會被放在項目根目錄下的固定目錄,其路徑就對應着這個編譯生成物應該推送至手機內的那個路徑.

一般的調試流程是: 修改代碼 -> 找到模塊根目錄編譯模塊 -> 編譯 -> 在編譯日誌中找到編譯產物路徑 -> 根據編譯產物路徑將生成物 adb push 到手機

有時一個模塊生成多個lib (我記得 installd 會生成7個),少推一個手機就起不來了.

有時一個修改涉及多個模塊,那上面的步驟就要重複多次.

我們廠當時代碼都放在了服務器上,編譯完成後,要把編譯生成物放在一箇中間服務器(便於審覈),再從中間服務器下載到本機,再從本機 push 到手機.那這個流程就又延長且繁瑣了,最終每一次編譯調試都要五分鐘左右,還經常性的出錯.

另外系統簽名肯定是要放在服務器的,要簽名就得上傳到簽名服務器. 某些模塊沒有簽名的話,直接推也會讓手機起不來.

最終要實現的腳本要完成下面事情:

1. 支持指定某個文件爲參數,自動找到相應的 Android.mk 編譯之

2. 支持指定多個上述文件.多個文件對應一個 Android.mk 時, duplicate 之. 對應多個時,逐個編譯之

3. 分析編譯日誌,找到所有編譯產物路徑

4. 分析編譯產物路徑,並用 adb push 逐個將編譯產物推送至手機

由於我們廠又多了箇中間服務器中轉過程,在以上步驟3之後的需求改爲如下:

4. 將解析得到的信息彙總,生成 adbpush.sh 的腳本,內含各個編譯產物要推送到手機內的路徑

5. 將編譯產物及 adbpush.sh 打包,並上傳至中間服務器

6. 本機編寫 adb_auto_push.sh 腳本,從中間服務器下載上一步的壓縮包

7. 解壓並對需要簽名的模塊簽名(到簽名服務器)

8. 執行壓縮包內的 adbpush.sh 腳本,將編譯產物推送至手機

基於中轉服務器,又寫了一個腳本,實現輪詢中轉服務器(每5秒),有新的符合規則的壓縮包則下載並推送.這樣看起來在服務器轉一手看起來就和在本機編譯體驗一樣了.

這個腳本最終完成後,極大的提高了相關工作效率和準確度.

代碼:

公司中轉服務器的那個腳本就不貼了,這裏只貼在本機編譯 Framework 並推送的那個腳本.

已經離開Framework相關工作太久,逐一分析太費時間了,這裏就偷懶只貼代碼了.

這個腳本其實是不限工作環境的,對於現在的 Android 版本,應該稍加修改也還可以用.

#       THIS SHELL IS ENVIRONMENT INDEPENDENT

#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.
#v3.1   2013-02-01

USAGE:
compile_and_push.sh [-t] [-x] [-d] [-u] [-l lunch_number] PATH

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: 這個腳本成型於4年前,很多地方處理的並不成熟,

比如找 git 項目根目錄的辦法

比如 sed 命令的使用

比如 true false 變量的處理

等等等等. 即使是截止到寫這篇文章的時間點,題主的bash水平依然有很多不足之處.

說人話就是: 學無止境,歡迎指教,和平討論~.
