我想从命令行设置Android开发环境,遇到以下问题:

wget http://dl.google.com/android/android-sdk_r22.0.5-linux.tgz

解压完成后,运行

tools/android update sdk --no-ui

但是,它跑起来太慢了

Fetching https://dl-ssl.google.com/android/repository/addons_list-2.xml

结果是在文件夹build-tools中什么都没有,我想要的是apapt和apkbuilder,因为我想从命令行构建apk而没有ant。


当前回答

如果你安装了sdkmanager(我使用MAC)

执行sdkmanager——list命令列出可用的包。

如果要安装构建工具,请从可用软件包列表中复制首选版本。

要安装首选版本,请运行

sdkmanager "build-tools;27.0.3"

但是,它跑起来太慢了

是的,我也遇到过同样的问题。有些文件下载非常慢(至少在过去几天是这样)。如果你想下载所有的东西,你可以做的不多。

结果是在文件夹build-tools中什么都没有,我想要的是apapt和apkbuilder,因为我想从命令行构建apk而没有ant。

你让它跑完吗?

您可以做的一件事是使用-t开关过滤正在下载的包。

例如:

tools/android update sdk --no-ui -t platform-tool

当我前几天尝试这样做时,我安装了18.0.0版本的构建工具。由于某种原因,最新版本18.0.1没有包含在这个过滤器中,获得它的唯一方法是使用——all开关安装所有东西。

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.

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。

默认情况下,命令行中的SDK管理器不包括列表中的构建工具。它们属于“过时”的类别。要查看所有可用的下载,使用

android list sdk --all

然后从命令行获取列表中的一个包,使用:

android update sdk -u -a -t <package no.>

其中-u代表——no-ui, -a代表——all, -t代表——filter。

如果你需要安装多个包,请:

android update sdk -u -a -t 1,2,3,4,..,n 

在1、2、…,n为上面list命令列出的包号

我就遇到了这个问题,所以我最终通过读取和解析可用工具列表来编写了一行bash dirty解决方案:

 tools/android update sdk -u -t $(android list sdk | grep 'Android SDK Build-tools' | sed 's/ *\([0-9]\+\)\-.*/\1/')
