安裝Oracle JDK
第一步：區(qū)分32位還是64位操作系統(tǒng)
先確定你的ubuntu linux是32位還是64位的秒啦，方法很多，這里介紹一種即可搀玖。
$uname -a
第二步：卸載OpenJDK
先執(zhí)行如下命令看是否安裝了OpenJDK余境，如果已經(jīng)安裝，會(huì)顯示java的信息灌诅。
$java -version
如果安裝了OpenJDK芳来，可用如下方法全部卸載：
$sudo apt-get purge openjdk-\*
第三步：下載Oracle JDK版本，選擇"Java SE Development Kit 6u45"延塑，然后在新打開的頁面點(diǎn)選接受Accept License Agreement. 接受之后绣张，選擇jdk-6u45-linux-x64.bin即可進(jìn)行下載。如果你沒有登錄关带，系統(tǒng)會(huì)先轉(zhuǎn)到登錄頁面侥涵，輸入你在Oracle網(wǎng)站注冊(cè)的用戶名和密碼即可。
第三步：安裝Oracle JDK
(1) 創(chuàng)建java目錄
$ sudo mkdir -p /usr/local/java
將你下載的jdk-6u45-linux-x64.bin拷貝至/usr/local/java目錄
$ cd /usr/local/java
$ sudo cp /home/dennis/Downloads/jdk-6u45-linux-x64.bin .
(2) 解壓bin文件
$ sudo chmod +x jdk-6u45-linux-x64.bin
$ sudo ./jdk-6u45-linux-x64.bin
$ sudo rm -rf jdk-6u45-linux-x64.bin
第四步：配置Orache JDK
(1) 配置JAVA_HOME和PATH環(huán)境變量
$ sudo vi /etc/profile
在該文件的末尾加上如下部分：
JAVA_HOME=/usr/local/java/jdk1.6.0_45
PATH=$PATH:$HOME/bin:$JAVA_HOME/bin
export JAVA_HOME
export PATH
(2) 配置ubuntu的JDK和JRE的位置
$ sudo update-alternatives --install "/usr/bin/java" "java" "/usr/local/java/jdk1.6.0_45/bin/java" 1
$ sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/local/java/jdk1.6.0_45/bin/javac" 1
$ sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/local/java/jdk1.6.0_45/bin/javaws" 1
(3) 配置Oracle為系統(tǒng)默認(rèn)JDK/JRE
$ sudo update-alternatives --set java /usr/local/java/jdk1.6.0_45/bin/java
$ sudo update-alternatives --set javac /usr/local/java/jdk1.6.0_45/bin/javac
$ sudo update-alternatives --set javaws /usr/local/java/jdk1.6.0_45/bin/javaws
配置完成后宋雏，執(zhí)行如下命令使其立即生效芜飘。
$ . /etc/profile
再次執(zhí)行"java -version"顯示如下：
dennis@dubuntu1404:~$ java -version
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 20.45-b01, mixed mode)
安裝必備工具軟件(Ubuntu 14.04 64 bit)
$ sudo apt-get install bison g++-multilib git gperf libxml2-utils
配置USB訪問權(quán)限
將如下內(nèi)容加入到/etc/udev/rules.d/51-android.rules文件中
# adb protocol on passion (Nexus One)
SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4e12", MODE="0600", OWNER="<username>"

SUBSYSTEM=="usb", ATTR{idVendor}=="18d1", ATTR{idProduct}=="4ee0", MODE="0600", OWNER="<username>"
然后執(zhí)行如下命令，將上述文件中的username替換為你的用戶名磨总。
$sudo sed -i 's/username/root/g' /etc/udev/rules.d/51-android.rules
下載源碼
安裝repo
(1) 創(chuàng)建目錄
$ mkdir ~/bin
$ PATH=~/bin:$PATH
(2) 下載repo工具
curl http://git-repo.googlecode.com/files/repo-1.12 > ~/bin/repo
(3) 增加可執(zhí)行權(quán)限
$ chmod a+x ~/bin/repo
初始化Repo客戶端
(1)創(chuàng)建目錄
$mkdir Android-4.4.2_r1
$cd Android-4.4.2_r1
(2) 初始化repo
$repo init -u https://android.googlesource.com/platform/manifest -b android-4.4.2_r1
下載源代碼
$repo sync
好了嗦明，慢慢等吧，短則數(shù)小時(shí)蚪燕，長(zhǎng)則幾天幾夜娶牌！我花了5個(gè)小時(shí)

============================================
開始編譯
qq@dubuntu1404:~/android-4.4.4_r1$ make -j4
j4中的數(shù)字跟你的CPU個(gè)數(shù)和核數(shù)有關(guān)
將img加載到物理機(jī)
編譯完成后，連接手機(jī)（nexus5）馆纳，打開USB調(diào)試诗良，運(yùn)行如下命令刷入img
$ adb reboot bootloader
// 系統(tǒng)將會(huì)重啟
$ fastboot flashall -w
