对于Android开发的朋友来说，首先要做的就是配置开发环境，目前官方提供的IDE是AndroidStudio，不过个人还是习惯于Eclipse。由于国内的网络环境原因，通过官方的SDK Manager的下载速度一般很慢，因此采用离线下载比较简单。简单来说就是先把安装需要的压缩包通过迅雷等P2P软件下载到本地，然后再配置改动一些参数来本地安装。但是一般方法费时费力，主要是因为网上贴出来的下载网盘链接或者官方下载地址总在不断更新，不具有时效性。这篇文章对Android SDK的下载和配置进行了分析，提供了有效获取离线SDK的方式。

原理概述

本文主要对SDK Manager如何解析xml进行分析，得到对应的文件下载地址，以及下载到本地后如何配置参数来完成Android SDK的安装。这种方法既不提供实时的下载地址和分享链接，又不会因为SDK地址更新失效，关键是分析弄清楚SDK Manager的工作原理。Android SDK主要通过Android SDK Manager来管理，而这个Manager管理资源主要包括

Tools

这部分主要有下列三个工具：

• Android SDK Tools
• Android SDK Platform-tools
• Android SDK Build-tools

Platform

这部分就包括对应不同Android版本的平台库，示例文件和google官方的API接口文件，以及对应版本的源码：

• SDK Platform
• Samples for SDK
• Google APIs
• Sources for Android SDK （始于API 14，也即是Android 4.0之后的版本才有源码可以通过Manager 下载管理）

Extras

以下的额外文件有些是必须的开发库，比如Support Library等，其他的主要是集成google的一些资源，比如应用商店google play等，各个文件的作用就不作介绍了，一般都能搜到相关资料。

• Android Support Library
• Android Support Repository
• Google Repository
• Google Play Licensing Library
• Google Play APK Expansion Library
• Google Play services for Froyo
• Google Play services
• Google USB Driver
• Google Play Billing Library
• Google AdMob Ads SDK
• Google Analytics App Tracking SDK
• Google Web Driver
• Google Cloud Messaging for Android Library
• Android Auto API Simulators

具体操作

首先得先在Eclipse中把插件ADT装好，不过在2013年时候Android官网已经提供集成ADT的Eclipse下载,最新官方版本已经更改为Android Studio了，但是都使用Android SDK Manager来管理。因此第一步安装ADT工作基本可以略过了（如果确实不会装，请自行查资料解决，不在本文讨论范围内），后续操作都是在已经安装好SDK Manager的前提下进行的。

Load XML文件

打开Manager就可以看到底下状态栏显示Parsing XML和Fetching 一些XML文件了，通过manager Log也可以看到爬取记录，如下图：

managerLog.png

解析到的的XML文件就是repository-10.xml，addons_list-2.xml，addon-6.xml，addon.xml。最重要是repository-10.xml和addon.xml这两个，前者包含了平台资源文件的下载地址，后者则主要是前面介绍的Extras内容地址。所以，只需要打开log窗口，然后复制出这两个XML文件的地址(比如本文写作时的地址是https://dl-ssl.google.com/android/repository/repository-10.xml 和https://dl-ssl.google.com/android/repository/addon.xml)，将其复制到浏览器打开保存或者直接用下载软件下载就可以了。

解析资源地址

通过上一步得到了repository-10.xml和addon.xml，接下来就是对应分析XML中的地址了，其实这两个XML打开后稍微分析下就可以发现规律了，如下所示可以在repository-10.xml文件中搜索每一行后面的跳到对应位置提取地址。

必须安装的TOOL资源：

• Tools
  Android SDK Tools
• Platform-tools
  Android SDK Platform-tools
• Build-tools
  Android SDK Build-tools

对于每一个API level :

• Platform
  SDK Platform
• Samples
  Samples for SDK
• Sources
  Sources for Android SDK
  在addon.xml文件中搜索跳到对应位置提取Google APIs地址。
• Google APIs

在addon.xml文件中搜索以下关键词定位到Extras类别的下载地址位置

• Extras
  Android Support Library
  Android Support Repository
  Google Repository
  Google Play Licensing Library
  Google Play APK Expansion Library
  Google Play services for Froyo
  Google Play services
  Google USB Driver
  Google Play Billing Library
  Google AdMob Ads SDK
  Google Analytics App Tracking SDK
  Google Web Driver
  Google Cloud Messaging for Android Library
  Android Auto API Simulators

提取SDK下载地址

推荐下载API Level为10、14、15、16、17、19的SDK，截至本文写作时的地址为:

安装配置

通过迅雷等软件直接下载到本地后都是压缩包，如图：
<img src="/images/sdkZip.png" height='50%' width='50%'/>
下一步就是找到SDK Manager的目录，打开sdk文件夹后，主要含有如下文件夹：

• add-ons
• build-tools
• extras
• platforms
• platform-tools
• samples
• sources
• temp
• tools

add-ons

对于add-ons文件夹，需要将google_apis-10_r02.zip（其他API Level类似）解压进去，并重命名为addon-google_apis-google-10，然后进入目录，新建source.properties文件，写入如下内容：

General Legal Terms\n\n14.1 The License Agreement constitutes the whole legal agreement between you and Google and governs your use of the SDK (excluding any services which Google may provide to you under a separate written agreement), and completely replaces any prior agreements between you and Google in relation to the SDK.\n\n14.2 You agree that if Google does not exercise or enforce any legal right or remedy which is contained in the License Agreement (or which Google has the benefit of under any applicable law), this will not be taken to be a formal waiver of Google's rights and that those rights or remedies will still be available to Google.\n\n14.3 If any court of law, having the jurisdiction to decide on this matter, rules that any provision of the License Agreement is invalid, then that provision will be removed from the License Agreement without affecting the rest of the License Agreement. The remaining provisions of the License Agreement will continue to be valid and enforceable.\n\n14.4 You acknowledge and agree that each member of the group of companies of which Google is the parent shall be third party beneficiaries to the License Agreement and that such other companies shall be entitled to directly enforce, and rely upon, any provision of the License Agreement that confers a benefit on (or rights in favor of) them. Other than this, no other person or company shall be third party beneficiaries to the License Agreement.\n\n14.5 EXPORT RESTRICTIONS. THE SDK IS SUBJECT TO UNITED STATES EXPORT LAWS AND REGULATIONS. YOU MUST COMPLY WITH ALL DOMESTIC AND INTERNATIONAL EXPORT LAWS AND REGULATIONS THAT APPLY TO THE SDK. THESE LAWS INCLUDE RESTRICTIONS ON DESTINATIONS, END USERS AND END USE.\n\n14.6 The License Agreement may not be assigned or transferred by you without the prior written approval of Google, and any attempted assignment without such approval will be void. You shall not delegate your responsibilities or obligations under the License Agreement without the prior written approval of Google.\n\n14.7 The License Agreement, and your relationship with Google under the License Agreement, shall be governed by the laws of the State of California without regard to its conflict of laws provisions. You and Google agree to submit to the exclusive jurisdiction of the courts located within the county of Santa Clara, California to resolve any legal matter arising from the License Agreement. Notwithstanding this, you agree that Google shall still be allowed to apply for injunctive remedies (or an equivalent type of urgent legal relief) in any jurisdiction.\n\nJune 2014.\n    
Pkg.LicenseRef=android-sdk-license
Pkg.Revision=2
Pkg.SourceUrl=https\://dl-ssl.google.com/android/repository/addon.xml

其他API版本，则需要改动上述代码中的对应数字和Revision号，即

AndroidVersion.ApiLevel=10
Pkg.Desc=Android + Google APIs, API 10, revision 2
Pkg.Revision=2

这三行中数字，比如将10改为14、15、17、19，revision后的2改为对应的1、2者3等，具体信息解压缩后的文件夹名称可以体现出来，google_apis-10_r02则说明API Level为10，Revision号为2。

build-tools

解压后重命名为版本号即可，如压缩包名称为build-tools_r21.1.2-windows.zip，解压后重命名文件夹为21.1.2放进build-tools文件夹即可。

extras

extras文件夹下主要为android和google这两个文件夹，将前面Extras列表下的Google开头文件对应压缩包解压后放在google文件夹里，Android开头的压缩包则解压缩后放进android文件夹。

platforms

直接将对应的android SDK版本解压后放进去即可，比如android-17_r03.zip解压后为android-4.2.2文件夹。

platform-tools

直接解压放进去即可

samples

比如解压samples-16_r01.zip得到android-4.1文件夹，重命名为android-16后放进samples文件夹。

sources

同上samples方法，解压后得到src文件夹，重命名为对应名称如android-16放进sources文件夹。

temp

通过SDK Manager下载的压缩包一般临时放在此文件夹下，安装完成后压缩包会被删除。

tools

直接解压放进去即可。
