命令行下載更新Android SDK

編輯:關於Android編程

前序

最近需要在服務器上用Jenkins自動打包Android app,從google官網上下載的Linux版本sdk結果發現裡面就只有一個tools目錄有文件,其他的都沒有。。。
無奈,服務器是沒有界面的,之前都習慣用IDE去安裝更新,現在嘗試用命令行下載更新了。

下載Android SDK for Linux

從google的官網下載最新Linux版本SDK,由於dl.google.com域名一直沒有被牆,所以才可以直接從官網下了。這點不錯~

$ wget https://dl.google.com/android/android-sdk_r24.4.1-linux.tgz

解壓
$ tar zxvf android-sdk_r24.4.1-linux.tgz

更新Android SDK

前面說到了,我們下載的這個包其實只有tools目錄下才有東西。既然google給了我們這個,表示這裡面肯定有可以更新SDK的工具啦。
其實就是tools/android這個文件

$ cd android-sdk-linux/tools

查看命令幫助
$ ./android --help
       Usage:
       android [global options] action [action options]
       Global options:
  -s --silent     : Silent mode, shows errors only.
  -v --verbose    : Verbose mode, shows errors, warnings and all messages.
     --clear-cache: Clear the SDK Manager repository manifest cache.
  -h --help       : Help on a specific command.

因為是首次安裝,所有有非常多的版本可下載。
我們可以有2個選擇:

安裝所有版本的SDK 只安裝我們需要SDK版本
因為是在服務器上,建議直接安裝所有版本的吧,不然後續可能有些app需要這個版本,又有的需要那個版本。還不如一開始就全部安裝好。

更新命令

根據上面的工具使用幫助,可以看到更新命令是使用update sdk
但是這個命令又是如何使用的呢?查看幫助

$ ./android update sdk --help

Usage:
       android [global options] update sdk [action options]
       Global options:
  -s --silent     : Silent mode, shows errors only.
  -v --verbose    : Verbose mode, shows errors, warnings and all messages.
     --clear-cache: Clear the SDK Manager repository manifest cache.
  -h --help       : Help on a specific command.

                     Action "update sdk":
  Updates the SDK by suggesting new platforms to install if available.
Options:
  -f --force     : Forces replacement of a package or its parts, even if
                   something has been modified.
  -n --dry-mode  : Simulates the update but does not download or install
                   anything.
     --proxy-host: HTTP/HTTPS proxy host (overrides settings if defined)
  -s --no-https  : Uses HTTP instead of HTTPS (the default) for downloads.
  -t --filter    : A filter that limits the update to the specified types of
                   packages in the form of a comma-separated list of
                   [platform, system-image, tool, platform-tool, doc, sample,
                   source]. This also accepts the identifiers returned by
                   'list sdk --extended'.
  -u --no-ui     : Updates from command-line (does not display the GUI)
     --proxy-port: HTTP/HTTPS proxy port (overrides settings if defined)
  -p --obsolete  : Deprecated. Please use --all instead.
  -a --all       : Includes all packages (such as obsolete and non-dependent
                   ones.)

在這裡,重點關注-u-t參數就好。

-u --no-ui  表示在命令行環境下使用,剛好符合我們服務器環境
-t --filter 表示過濾,只安裝指定版本的sdk 

好了,我們現在就開始更新吧

首先下載更新全部可安裝的SDK版本,不指定過濾即可
$ ./android update sdk -u

經過漫長時間的等待基本都安裝好了。。
如果只需要安裝指定版本的話,就需要過濾了,如何過濾呢?我們上面已經介紹查看可安裝更新sdk版本命令list sdk了。根據查看到的序號過濾即可。

只安裝指定序號的版本
$ ./android  update sdk -u -t 序號
如:安裝Build-tools, revision 24.0.3
$ ./android update sdk -u -t 3
需要同意license,輸入 y 回車即可

安裝後可跳轉到上一級目錄查看是否已經有了。

$ cd ..
$ ls
add-ons  build-tools  platforms  SDK Readme.txt  temp  tools
$ cd build-tools
$ ls
24.0.3

可以看到安裝成功了。

總結

通過這些我們也可以推測出其實那些IDE圖形界面底層調用的也是這些命令吧。。
