过程：

根据链接下载 三个 tgz的文件，

解压后是sh文件放到源码的跟目录，

执行sh文件，会在源码根目录下生存vendor文件夹。

命令:

mkdir drivers

内核：

参考：

参考网址：http://blog.csdn.net/qq1084283172/article/details/54880488

官网：https://source.android.com/source/building-kernels

内核配置菜单的支持库：

sudo apt-get install lib32ncurses5-dev

内核编译：

cd android-4.4.4_r1/

mkdir kernel

cd kernel/

git clone https://android.googlesource.com/kernel/msm.git

git branch -a

git checkout origin/android-msm-hammerhead-3.4-kk-r1

export PATH=/home/fbb/android-4.4.4_r1/prebuilts/gcc/linux-x86/arm/arm-eabi-4.7/bin:$PATH

export CROSS_COMPILE=/home/fbb/android-4.4.4_r1/prebuilts/gcc/linux-x86/arm/arm-eabi-4.7/bin/arm-eabi-

export ARCH=arm

export SUBARCH=arm

make distclean//内核编译清空

make hammerhead_defconfig

make menuconfig //调用配置的菜单。enable loadable module suppot (启动模块支持，驱动模块内部的一些设置)

make -j16

编译后的内核文件路径:arch/arm/boot/zImage-dtb

查看内核版本命令：

cd arch/arm/boot/

dd if=zImage-dtb bs=1 skip=$(LC_ALL=C od -Ad -x -w2 zImage-dtb | grep 8b1f | cut -d ' ' -f1 | head -1) | zgrep -a 'Linux version'

编译完后的内核版本：

Linux version 3.4.0-g9eb14ba (fbb@fbb-pc) (gcc version 4.7 (GCC) ) #1 SMP PREEMPT Mon Aug 14 11:29:51 CST 2017

新编译的内核替换原来的内核：

cp /home/fbb/android-4.4.4_r1/device/lge/hammerhead-kernel/zImage-dtb /home/fbb/test/zImage-dtb //原来的内核备份

cp /home/fbb/android-4.4.4_r1/kernel/msm/arch/arm/boot/zImage-dtb /home/fbb/android-4.4.4_r1/device/lge/hammerhead-kernel/zImage-dtb

系统自带的内核版本：

Linux version 3.4.0-gd59db4e (android-build@vpbs1.mtv.corp.google.com)

(gcc version 4.7 (GCC) ) #1 SMP PREEMPT Mon Mar 17 15:16:36 PDT 2014

Nexus 5内核文件路径：device/lge/hammerhead-kernel

此处有两种方法：

1，把新编译的内核替换为下载下来的内核，然后重新对android源码编译。

2，用工具重新置编辑bootimg，然后只刷boot.img.(这种方法是，android源码已经编译完了，后编译的内核。建议不要用这种，亲测的结果是，内核一会是之前的版本，一会是新编译的版本)

编译android源码

参考：

android 源码官网：https://source.android.com/source/building

参考网址：http://blog.csdn.net/qq1084283172/article/details/54562606

清理:为了确保新安装的二进制文件在解压后会被适当考虑在内，请使用以下命令删除所有以前编译操作的已有输出：

make clobber

设置环境:使用 envsetup.sh 脚本初始化环境。请注意，将 source 替换成 .(一个点)可以省去一些字符，这种简写形式在文档中更为常用。

source build/envsetup.sh

或

. build/envsetup.sh

选择目标：

编译代码：

刷机

参考(网页下面写了一些android的驱动的配置)：http://blog.csdn.net/qq1084283172/article/details/54562606

前提：先配置usb的配置文件：

sudo gedit /etc/udev/rules.d/51-android.rules

sudo sed -i 's/username/fbb/g' /etc/udev/rules.d/51-android.rules

进入刷机模式的命令：

adb reboot bootloader

查看usb：

lsusb

真机刷机：

fastboot -w flashall
