刷机使用. 不需要编译源码, 直接刷机.
下载刷机包
https://developers.google.com/android/images
https://developers.google.com/android/ota
刷入:
$sudo ./flash_all.sh
源码下载 #
repo init -u https://aosp.tuna.tsinghua.edu.cn/platform/manifest -b android-6.0.1_r77
repo sync -j8
适用于pixel 的: NZH54D android-7.1.2_r33 OPM4.171019.021.P1 android-8.1.0_r38
repo init -u https://aosp.tuna.tsinghua.edu.cn/platform/manifest -b android-7.1.2_r33
repo init -u https://aosp.tuna.tsinghua.edu.cn/platform/manifest -b android-8.1.0_r38
编译 #
直接编译userdebug版本, 方便我们调试
安装jdk
sudo add-apt-repository ppa:openjdk-r/ppa
sudo apt-get update
sudo apt-get install openjdk-7-jdk
编译, 如果要刷真机的话, 需要提前下载驱动到源码目录, 并解压之后运行.sh, ACCEPT后释放出来驱动相关文件.(https://developers.google.com/android/drivers)
$source ./build/envsetup.sh
$lunch
编译全部源码
$make -j12
编译某个module
$make -j12 libart_32
输入系统
这里不需要sudo
$fastboot flashall -w
root #
root无源码的机型.
- 解锁boot
- 刷入twrp
- 装入supersu.apk
- 重启

# Reboot System
调试 #
更改system分区读写权限
$adb disable verity
$mount -o remount,rw /system
emulator测试 #
- 列出创建avd
emulator -list-avd
- emulator 启动avd
$emulator -avd PixelN
- 使
system分区可写
$emulator -writable-system -avd PixelN
启动之后
$adb remount
