更新

最新版本引入了sdkmanager，这是一个命令行工具，允许您查看、安装、更新和卸载Android SDK包。

sdkmanager工具在Android SDK Tools(25.2.3及以上版本)包中提供，位于android_sdk/ Tools /bin/目录下。

  sdkmanager [--uninstall] [<common args>] [--package_file <file>] [<packages>...]
  sdkmanager --update [<common args>]
  sdkmanager --list [<common args>]
  sdkmanager --licenses [<common args>]

In its first form, installs, or uninstalls, or updates packages.
    By default, the listed packages are installed or (if already installed)
    updated to the latest version.

    --uninstall: uninstalled listed 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), all installed packages are
    updated to the latest version.

In its third form, all installed and available packages are printed
    out.

In its fourth form (with --licenses), show and offer the option to
     accept licenses for all available packages that have not already been
     accepted.

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.

因此，要更新运行的包

sdkmanager --update

为了接受许可证，

yes | sdkmanager --licenses

旧的答案

(请注意:android命令已弃用!)

你离自动化越近的可能是:

android update sdk --no-ui

Android为自动更新提供了以下选项:

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
  -u --no-ui    Updates from command-line (does not display the GUI)
  -o --obsolete Installs obsolete packages
  -t --filter   A filter that limits the update to the specified types of packages in the form of
                a comma-separated list of [platform, tool, platform-tool, doc, sample, extra]
  -s --no-https Uses HTTP instead of HTTPS (the default) for downloads
  -n --dry-mode Simulates the update but does not download or install anything

如果您想要列出可用于安装的软件包，则可以使用

android list sdk

例如，您将获得一个有序的包列表

Packages available for installation or update: 9
   1- ARM EABI v7a System Image, Android API 15, revision 2
   2- Intel x86 Atom System Image, Android API 15, revision 1
   3- Android Support, revision 8
   4- Google AdMob Ads SDK, revision 6
   5- Google Analytics SDK, revision 2
   6- Google Play APK Expansion Library, revision 1
   7- Google Play Billing Library, revision 2
   8- Google Play Licensing Library, revision 2
   9- Google Web Driver, revision 2

此外，如果使用——filter选项，可以将更新限制在所需的组件上

android update sdk --filter <component> --no-ui

哪个组件是一个或多个

android列表SDK返回的数字(即1，也称为包索引) 附加组件 医生 额外的 平台 platform-tool 样本 源 系统映像 工具

或可以是一个或多个特定的标识符。例如，如果你只想下载一小部分特定的软件包，你可以这样做:

android update sdk -u --filter platform-tools,android-16,extra-android-support

您将获得平台工具、API级别16和支持包JAR文件。如果您只是构建一个构建机器，并且必须为下载所有您永远不会使用的额外内容付费，那么这非常方便。

要查看您可以使用的可用选项，例如help

android --help list sdk

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

                   Action "list sdk":
  Lists remote SDK repository.
Options:
  -o --obsolete  : Deprecated. Please use --all instead.
  -a --all       : Lists all available packages (including obsolete and
                   installed ones)
     --proxy-host: HTTP/HTTPS proxy host (overrides settings if defined)
     --proxy-port: HTTP/HTTPS proxy port (overrides settings if defined)
  -s --no-https  : Uses HTTP instead of HTTPS (the default) for downloads.
  -e --extended  : Displays extended details on each package
  -u --no-ui     : Displays list result on console (no GUI) [Default: true]

从Android Plugin for Gradle version 2.2.0开始，丢失的SDK组件会自动下载。

我也对此感到沮丧，并建立了一个名为com.quittle的Gradle插件。Setup-android-sdk会检测并安装你需要的东西。它可以在Windows, OS X和Linux上工作，如果你用Gradle构建，它不需要任何额外的依赖。

对于那些还在寻找下载所有Android软件包的方法的人，我已经写了一个脚本来完成这个任务。它将下载所有未过时的包。

#!/binbash
# Install all non-obsolete Android SDK packages.
# author: Tai Le Tien (letientai299 at gmail.com)

function install_sdk {
  android update sdk -u -s -a -t "$1"
}

function fetch_non_obsoled_package_indices {
  # Fetch the SDK list using non-https connections
  android list sdk -u -s -a |\
    # Filter obsoleted packages
    sed '/\(Obsolete\)/d' |\
    # Filter to take only the index number of package
    sed 's/^[ ]*\([0-9]*\).*/\1/' |\
    # Remove the empty lines
    sed -n 's/^[^ $]/\0/p'
}

for package_index in  $(fetch_non_obsoled_package_indices)
do
  echo "====================================================================="
  echo "Start to install package:  ${package_index}"
  echo "====================================================================="
  # Auto accept license
  echo -e "y" | install_sdk "${package_index}"
  echo
  echo
done

你也可以在我的GitHub存储库中看到它

优点:

不依赖期望。 无头的。

缺点:

你仍然需要手动安装基本的SDK，并将android放到你的路径中。 该脚本只能在Unix上运行。

一个脚本只下载需要的，非{过时的，source, emultor -image, doc}包:

#!/bin/bash
set -e

# cd into where tools/android can be found
if [[ -d "$ANDROID_HOME" ]]; then
  cd "$ANDROID_HOME"
elif [[ -x "$(dirname "$0")/tools/android" ]]; then
  cd "$(dirname "$0")"
else
  echo "FAILED: Cannot find ANDROID_HOME/tools/android"
  exit 1
fi

android () {
  "$(dirname $0)/tools/android" "$@"
}

needed_packages () {
  android list sdk -u -s -e         \
    | grep '^id:'                   \
    | cut -d'"' -f2                 \
    | grep -v 'source'              \
    | grep -v 'sys-img'             \
    | grep -v 'doc'                 \
    | paste -d, -s -
}

main () {
  (while : ; do
  echo 'y'
  sleep 1
  done) | android update sdk -u -s -a -t "$(needed_packages)"
}

main
