Android SDK Tools 25.2.3版本(及更高版本)包含了新的工具sdkmanager，它简化了从命令行安装构建工具的任务。 它位于android_sdk/tools/bin文件夹中。

用法(来自文档):

List installed and available packages: sdkmanager --list [options] \ [--channel=channel_id] // Channels: 0 (stable), 1 (beta), 2 (dev), or 3 (canary) Use the channel option to include a package from a channel up to and including channel_id. For example, specify the canary channel to list packages from all channels. Install packages: sdkmanager packages [options] The packages argument is an SDK-style path, wrapped in quotes (for example, "build-tools;25.0.0" or "platforms;android-25"). You can pass multiple package paths, separated with a space, but they must each be wrapped in their own set of quotes.

示例用法(在我的Mac上):

alex@mbpro:~/sdk/tools/bin$ ls ../../build-tools/  
25.0.0/   
alex@mbpro:~/sdk/tools/bin$ ./sdkmanager "build-tools;25.0.2"  
done   
alex@mbpro:~/sdk/tools/bin$ ls ../../build-tools/  
25.0.0/ 25.0.2/

您还可以指定各种选项，例如强制所有连接使用HTTP(——no_https)，或者为了使用代理服务器(——proxy_host=address和——proxy_port=port)。

要检查可用选项，使用——help标志。在我的机器(Mac)上，输出如下:

alex@mbpro:~/sdk/tools/bin$ ./sdkmanager --help
Usage: 
  sdkmanager [--uninstall] [<common args>] \
    [--package_file <package-file>] [<packages>...]
  sdkmanager --update [<common args>]
  sdkmanager --list [<common args>]

In its first form, installs, or uninstalls, or updates packages.
    <package> is a sdk-style path (e.g. "build-tools;23.0.0" or 
             "platforms;android-23").
    <package-file> is a text file where each line is a sdk-style path
                   of a package to install or uninstall.
    Multiple --package_file arguments may be specified in combination
     with explicit paths.
In its second form (with --update), currently installed packages are
    updated to the latest version.
In its third form, all installed and available packages are printed out.

Common Arguments:
    --sdk_root=<sdkRootPath>: Use the specified SDK root instead of the SDK containing this tool
    --channel=<channelId>: Include packages in channels up to <channelId>.
                           Common channels are:
                           0 (Stable), 1 (Beta), 2 (Dev), and 3 (Canary).

    --include_obsolete: With --list, show obsolete packages in the
                        package listing. With --update, update obsolete
                        packages as well as non-obsolete.
    --no_https: Force all connections to use http rather than https.
    --proxy=<http | socks>: Connect via a proxy of the given type.
    --proxy_host=<IP or DNS address>: IP or DNS address of the proxy to use.
    --proxy_port=<port #>: Proxy port to connect to.

* If the env var REPO_OS_OVERRIDE is set to "windows",
  "macosx", or "linux", packages will be downloaded for that OS.

Android更新SDK

此命令将更新和安装所有最新版本的SDK工具，构建工具，SDK平台工具。

这是我的工作。

当我试图从命令行安装所有Android SDK相关的东西时，我遇到了一个很棒的信息来源，就是这个Dockerfile。在Dockerfile中，您可以看到作者执行了一个命令来安装平台工具和构建工具，而没有任何其他交互。在行动计划提出的情况下，该命令将被调整为:

echo y | $ANDROID_HOME/tools/android update sdk --all --filter build-tools-21.1.0 --no-ui

Try

1. 列出所有软件包

android list sdk --all

2. 使用以下命令安装包

android update sdk -u -a -t package1, package2, package3 //comma seperated packages obtained using list command 

大多数答案似乎忽略了这样一个事实，即您可能需要在没有超级用户权限的无头环境中运行更新，这意味着脚本必须自动回答所有y/n许可提示。

下面是一个例子。

FILTER=tool,platform,android-20,build-tools-20.0.0,android-19,android-19.0.1

( sleep 5 && while [ 1 ]; do sleep 1; echo y; done ) \
    | android update sdk --no-ui --all \
    --filter ${FILTER}

No matter how many prompts you get, all of those will be answered. This while/sleep loop looks like simulation of the yes command, and in fact it is, well almost. The problem with yes is that it floods stdout with 'y' and there is virtually no delay between sending those characters and the version I had to deal with had no timeout option of any kind. It will "pollute" stdout and the script will fail complaining about incorrect input. The solution is to put a delay between sending 'y' to stdout, and that's exactly what while/sleep combo does.

expect在一些linux发行版上默认是不可用的，我没有办法将它作为我的CI脚本的一部分安装，所以必须使用最通用的解决方案，没有什么比简单的bash脚本更通用的了，对吗?

事实上，我在博客上写过(NSBogan)，如果你感兴趣，可以在这里查看更多细节。
