自己动手编译最新Android源码及SDK ： http://blog.csdn.net/dd864140130/article/details/51718187官方文档，怎样编译sdk ： https://android.googlesource.com/platform/sdk/+/master/docs/howto_build_SDK.txt
Android N Car源码到手，但官方还没有发布最新的SDK，源码中开发应用就有很大的难度，有了自己的SDK，无论framework层如何变动，都可以在Android Studio中开发得心应手。

1- Foreword
-----------
This document explains how to build the Android SDK and the ADT Eclipse plugin.
It is designed for advanced users which are proficient with command-line
operations and know how to setup the pre-required software.
Basically it‘s not trivial yet when done right it‘s not that complicated.
--------------------------------------
2- Building an SDK for MacOS and Linux
--------------------------------------
First, setup your development environment and get the Android source code from
git as explained here:
http://source.android.com/source/download.html
For example for the cupcake branch:
$ mkdir ~/my-android-git
$ cd ~/my-android-git
$ repo init -u https://android.googlesource.com/platform/manifest -b master -g all,-notdefault,tools
$ repo sync
Then once you have all the source, simply build the SDK using:
$ cd ~/my-android-git
$ . build/envsetup.sh
$ lunch sdk-eng
$ make sdk
This will take a while, maybe between 20 minutes and several hours depending on
your machine. After a while you‘ll see this in the output:
Package SDK: out/host/darwin-x86/sdk/android-sdk_eng.<build-id>_mac-x86.zip
Some options:
- Depending on your machine you can tell ‘make‘ to build more things in
parallel, e.g. if you have a dual core, use "make -j4 sdk" to build faster.
- You can define "BUILD_NUMBER" to control the build identifier that gets
incorporated in the resulting archive. The default is to use your username.
One suggestion is to include the date, e.g.:
$ export BUILD_NUMBER=${USER}-`date +%Y%m%d-%H%M%S`
There are certain characters you should avoid in the build number, typically
everything that might confuse ‘make‘ or your shell. So for example avoid
punctuation and characters like $ & : / \ < > , and .
------------------------------
3- Building an SDK for Windows
------------------------------
Full Windows SDK builds are now only supported on Linux -- most of the
framework is not designed to be built on Windows so technically the Windows
SDK is build on top of a Linux SDK where a few binaries are replaced. So it
cannot be built on Windows, and it cannot be built on Mac, only on Linux.
I‘ll repeat this again because it‘s important:
To build the Android SDK for Windows, you need to use a *Linux* box.
A- Pre-requisites
-----------------
Before you can even think of building the Android SDK for Windows, you need to
perform the steps from section "2- Building an SDK for MacOS and Linux" above:
setup and build a regular Linux SDK. Once this working, please continue here.
Under Ubuntu, you will need the following extra packages:
$ sudo apt-get install tofrodos
tofrodos adds a unix2dos command
B- Building
-----------
To build, perform the following steps:
$ . build/envsetup.sh
$ lunch sdk-eng
$ make win_sdk
Note that this will build both a Linux SDK then a Windows SDK.
The result is located at
out/host/windows/sdk/android-sdk_eng.${USER}_windows/
C- Building just the tools
--------------------------------------
You can also build isolated windows tools directly on Linux without building
the full SDK.
To build, perform the following steps:
$ cd ~/my-android-git
$ . build/envsetup.sh
$ lunch sdk-eng
$ make winsdk-tools
A specific tool can be built using:
$ make host_cross_adb
Then the binaries are located at
out/host/windows-x86/bin/adb.exe
-------------------------------------
4- Building an ADT plugin for Eclipse
-------------------------------------
We‘ve simplified the steps here.
It used to be that you‘d have to download a specific version of
Eclipse and install it at a special location. That‘s not needed
anymore.
Instead you just change directories to your git repository and invoke the
build script by giving it a destination directory and an optional build number:
$ mkdir ~/mysdk
$ cd ~/my-android-git # <-- this is where you did your "repo sync"
$ sdk/eclipse/scripts/build_server.sh ~/mysdk $USER
The first argument is the destination directory. It must be absolute. Do not
give a relative destination directory such as "../mysdk" -- this would make the
Eclipse build fail with a cryptic message:
BUILD SUCCESSFUL
Total time: 1 minute 5 seconds
**** Package in ../mysdk
Error: Build failed to produce ../mysdk/android-eclipse
Aborting
The second argument is the build "number". The example used "$USER" but it
really is a free identifier of your choice. It cannot contain spaces nor
periods (dashes are ok.) If the build number is missing, a build timestamp will
be used instead in the filename.
The build should take something like 5-10 minutes.
When the build succeeds, you‘ll see something like this at the end of the
output:
ZIP of Update site available at ~/mysdk/android-eclipse-v200903272328.zip
or
ZIP of Update site available at ~/mysdk/android-eclipse-<buildnumber>.zip
When you load the plugin in Eclipse, its feature and plugin name will look like
"com.android.ide.eclipse.adt_0.9.0.v200903272328-<buildnumber>.jar". The
internal plugin ID is always composed of the package, the build timestamp and
then your own build identifier (a.k.a. the "build number"), if provided. This
means successive builds with the same build identifier are incremental and
Eclipse will know how to update to more recent ones.

5- Conclusion
-------------
This completes the howto guide on building your own SDK and ADT plugin.
