repo init -u https://android.googlesource.com/platform/manifest
repo sync 之后
這樣初始化之后，相當於下載了全部的分支,
本想編譯源碼燒錄到手機Nexus 5，編譯時才發現找不到aosp_hammerhead_userdebug，畢竟nexus5明確不支持android-7.0
那么如何切換成自己想要的分支
查看可切換的分支
cd .repo/manifests
git branch -a | cut -d / -f 3
以android-6.0.1_r8為例
repo start android-6.0.1_r8 --all
查看當前的分支
repo branches
示例如下：
但最終還是無法完成編譯
其實命令repo start android-6.0.1_r8 --all 只是在每個git庫上新建一個分支，代碼並不會切到指定分支
repo abandon android-6.0.1_r8 清除本地分支
-----------------------------------分割線-------------------------------------------
上面使用每月初始化包的方式沒能通過編譯，無奈，老老實實下載吧
1、下載
mkdir aosp cd aosp repo init -u https://aosp.tuna.tsinghua.edu.cn/platform/manifest -b android-6.0.1_r3
sh myrepo.sh
myrepo.sh是為避免repo失敗過程，對repo sync 重試過程進行的封裝，見下方
#!/bin/sh repo sync -j4 while [ $? -ne 0 ] do repo sync -j4 done
同步過程出現 curl: (22) The requested URL returned error: 404 Not Found Server does not provide clone.bundle; ignoring. 直接無視即可
下載完整個目錄大小為54G ninjame@ubuntu1604:~$ du -sh aosp/ 54G aosp/
2、編譯

據說這個錯誤只在ubuntu16.04 上出現
1 更換軟件源為阿里雲
為了更快的安裝軟件，我們需要更換軟件源為國內的軟件源，這里推薦使用Ubuntu官方指定的國內軟件源阿里雲，博主之前使用的是網易的軟件源，結果發現OpenJDK7裝不上去，於是換成了阿里的，具體方法是：
sudo gedit /etc/apt/sources.list 在文件最前面加入下面代碼：
deb http://mirrors.aliyun.com/ubuntu/ quantal main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ quantal-security main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ quantal-updates main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ quantal-proposed main restricted universe multiverse deb http://mirrors.aliyun.com/ubuntu/ quantal-backports main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ quantal main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ quantal-security main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ quantal-updates main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ quantal-proposed main restricted universe multiverse deb-src http://mirrors.aliyun.com/ubuntu/ quantal-backports main restricted universe multiverse2 安裝依賴
sudo apt-get install -y git flex bison gperf build-essential libncurses5-dev:i386 sudo apt-get install libx11-dev:i386 libreadline6-dev:i386 libgl1-mesa-dev g++-multilib sudo apt-get install tofrodos python-markdown libxml2-utils xsltproc zlib1g-dev:i386 sudo apt-get install dpkg-dev libsdl1.2-dev libesd0-dev sudo apt-get install git-core gnupg flex bison gperf build-essential sudo apt-get install zip curl zlib1g-dev gcc-multilib g++-multilib sudo apt-get install libc6-dev-i386 sudo apt-get install lib32ncurses5-dev x11proto-core-dev libx11-dev sudo apt-get install lib32z-dev ccache sudo apt-get install libgl1-mesa-dev libxml2-utils xsltproc unzip m4Ubuntu 16.04請務必使用上面的依賴，Ubuntu 16.04需要的依賴和Ubuntu 14.04所需要的依賴是不同的
3 修改源碼
修改 mydroid/art/build/Android.common_build.mk 文件，定位到75行，將下面的代碼：
ifneq ($(WITHOUT_HOST_CLANG),true)改為：
ifeq ($(WITHOUT_HOST_CLANG),false)如果不修改這里，會遇到一個比較棘手的編譯錯誤，修改的目的是把CLANG這個編譯選項關掉，詳見后面的編譯記錄，百度搜狗都無解，這個錯誤只會在Ubuntu16.04上遇到，Ubuntu14.04則不存在這個問題，

3、刷機
刷機過程碰到 fastboot reboot < waiting for any device > fastboot devices no permissions (verify udev rules); see [http://developer.android.com/tools/device.html] fastboot fastboot命令一直識別不了手機，一開始以為時fastboot版本的問題，后來發現不是這么回事 需要設置usb權限 因為ubuntu這樣的系統都是默認以非root身份在運行的，要使用usb調試，需要sudo支持。 fastboot模式下插入手機 $ lsusb ninjame@ubuntu1604:~$ lsusb Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 002: ID 04d9:a0cd Holtek Semiconductor, Inc. Bus 001 Device 030: ID 18d1:4ee0 Google Inc. Bus 001 Device 003: ID 093a:2510 Pixart Imaging, Inc. Optical Mouse Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub $sudo vim /etc/udev/rules.d/60-android.rules //60-android.rules為新建的。 加入以下內容： SUBSYSTEM=="usb", ATTRS{idVendor}=="18d1", ATTRS{idProduct}=="4ee0",MODE="0666" 其中的idvendor idProduct指的是USB的ID可以使用lsusb查詢得到。 比如我的是： lsusb Bus 001 Device 030: ID 18d1:4ee0 Google Inc. ID 18d1 就是idVendor ，4ee0就是 idProduct 運行命令，重啟udev： $sudo chmod a+rx /etc/udev/rules.d/60-android.rules $sudo service udev restart (很重要)拔掉usb重新連上再執行： fastboot devices ninjame@ubuntu1604:~$ fastboot devices 0779af0143a66640 fastboot
