配置Ubuntu13.10 64bit 编译Android源码

本文提供了一种在Ubuntu 13.10 Saucy Salamander 64位系统上初始化全新Android编译环境的方法,包括安装正确的JDK、必备软件包及设置repo工具。

From XDA

Initializing a fresh Android Build Environment in Ubuntu 13.10 sucks, right? The instructions at the AOSP page are outdated and inaccurate. Near as I can tell, they try to have you install 2 JDKs, the first one not even being the correct link for Saucy Salamander, and the second being OpenJDK. Which might work. But I dunno about all that, I'd rather have Oracle's official stamp when it comes to building for Android.


Currently most of the guides are up to 12.04 LTS, which is fine and dandy, but being on the cutting edge is nice too.

This guide applies to all variations of Ubuntu 13.10 Saucy Salamander 64 bit. Do not use the 32 Bit version. Also, PAY CLOSE ATTENTION when to use "sudo" and when to not. It can make things funky if you do something as root that you shouldn't.

Much thanks goes out to Google, ProTekk, Canonical, and everyone else that I read a random paragraph here and snippet there.

First, let's set up the correct JDK.

Many of you probably have some kind of wrong Java installed unless you're starting with a fresh Ubuntu base, and even then maybe.

Let's get rid of that. Copy and paste this into a Terminal window:

Code:
sudo apt-get purge openjdk-\* icedtea-\* icedtea6-\*
Follow the instructions to remove OpenJDK. If you must keep it, it's possible. But I'm not going to tell you how to do it here. I don't want any chance of confusion or mistake.

Now copy and paste the following into the Terminal:

Code:
sudo add-apt-repository ppa:webupd8team/java
This will add the correct PPA to your system for updated builds of Java 6 JDK that are compatible with 13.10. No more unrecognized Java version errors! And it will update automatically with the rest of your system.

Next, we actually need to install the package. More copy-paste:

Code:
sudo apt-get update && sudo apt-get install oracle-java6-installer
Follow the on-screen instructions. You have to Accept the Licensing Agreement to complete the install. Hopefully no human centipede clauses.

Let's make sure the correct version of Java is activated, run the following Terminal command:

Code:
java -version
You should see something like the following:

Code:
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01, mixed mode)
Ok, back to a fresh Terminal prompt. Time for installing the guts to build stuff in Ubuntu:

Code:
sudo apt-get install git-core ccache gnupg flex bison gperf build-essential zip curl zlib1g-dev zlib1g-dev:i386 libc6-dev lib32ncurses5 lib32z1 lib32bz2-1.0 lib32ncurses5-dev x11proto-core-dev libx11-dev:i386 libreadline6-dev:i386 lib32z-dev libgl1-mesa-glx:i386 libgl1-mesa-dev g++-multilib mingw32 tofrodos python-markdown libxml2-utils xsltproc readline-common libreadline6-dev libreadline6 lib32readline-gplv2-dev libncurses5-dev lib32readline5 lib32readline6 libreadline-dev libreadline6-dev:i386 libreadline6:i386 bzip2 libbz2-dev libbz2-1.0 libghc-bzlib-dev lib32bz2-dev libsdl1.2-dev libesd0-dev squashfs-tools pngcrush schedtool libwxgtk2.8-dev python
When that is done installing, run the following command in your Terminal window:

Code:
sudo ln -s /usr/lib/i386-linux-gnu/mesa/libGL.so.1 /usr/lib/i386-linux-gnu/libGL.so
That's it on the package side of things.

You guessed it, time for more Terminal. This really is the easiest way, seriously. And it's totally worth it when you're basking in the glory of a bunch of people on XDA.

The binary for a program called "repo" will let you talk to git servers and download all that precious source code. That second part after the && allows it to be executable:

Code:
mkdir ~/bin && curl http://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo && chmod a+x ~/bin/repo
Use your favorite text editor to open ~/.bashrc

I like nano:

Code:
sudo nano ~/.bashrc
At the very bottom, add the following line:

Code:
export PATH=~/bin:$PATH
Save it. In nano that would be Ctrl-O and then Enter. Then Ctrl-X to exit back to a prompt. Restart bash:

Code:
source ~/.bashrc
In the terminal, navigate to where you would like to store the Android source code. The directions below will make it in your home folder, but if you have limited space, you may want to create it somewhere else. Faster is better, i.e. SSD would be best, USB external is basically unusable. Here we go:

Code:
mkdir ~/android
cd ~/android
Now you're going to initialize the repo. Here's where you decide the flavor of Android you want to build for, ie AOKP, CyanogenMod, AOSP etc. The following, for the purposes of this tutorial, will initialize for AOKP Jellybean MR-2:

Code:
repo init -u git://github.com/AOKP/platform_manifest.git -b jb-mr2
Almost there. Last step, but it's a doozy. You're going to get the source. Prepare yourself, mere mortal. 10+ GB of downloading await you. Don't worry, it's automated. Go to sleep. Eat something. Perhaps you have heard of this new thing the kids are doing called "going outside"? Yeah, I didn't think so. Me neither. The final terminal command, to be run from your android directory:

Code:
repo sync
Check back periodically every hour or so. It really all depends on how fast your internet connection is.

That should be everything. Now you're ready to build Android the right way. Luck!
内容概要:本文详细介绍了一个基于Java和Vue的联邦学习隐私保护推荐系统的设计与实现。系统采用联邦学习架构,使用户数据在本地完成模型训练,仅上传加密后的模型参数或梯度,通过中心服务器进行联邦平均聚合,从而实现数据隐私保护与协同建模的双重目标。项目涵盖完整的系统架构设计,包括本地模型训练、中心参数聚合、安全通信、前后端解耦、推荐算法插件化等模块,并结合差分隐私与同态加密等技术强化安全性。同时,系统通过Vue前端实现用户行为采集与个性化推荐展示,Java后端支撑高并发服务与日志处理,形成“本地训练—参数上传—全局聚合—模型下发—个性化微调”的完整闭环。文中还提供了关键模块的代码示例,如特征提取、模型聚合、加密上传等,增强了项目的可实施性与工程参考价值。 适合人群:具备一定Java和Vue开发基础,熟悉Spring Boot、RESTful API、分布式系统或机器学习相关技术,从事推荐系统、隐私计算或全栈开发方向的研发人员。 使用场景及目标:①学习联邦学习在推荐系统中的工程落地方法;②掌握隐私保护机制(如加密传输、差分隐私)与模型聚合技术的集成;③构建高安全、可扩展的分布式推荐系统原型;④实现前后端协同的个性化推荐闭环系统。 阅读建议:建议结合代码示例深入理解联邦学习流程,重点关注本地训练与全局聚合的协同逻辑,同时可基于项目架构进行算法替换与功能扩展,适用于科研验证与工业级系统原型开发。
