Android Framework之编译源码

熬夜喝酒写代码2025-12-26 10:35

环境

系统版本：Ubuntu 20.04

内存：32G

硬盘：1T

Android版本：Android10

开发环境搭建

bash 复制代码

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install git-core gnupg flex bison build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 libncurses5 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z1-dev libgl1-mesa-dev libxml2-utils xsltproc unzip fontconfig python

下载repo工具

bash 复制代码

mkdir ~/bin
curl https://mirrors.tuna.tsinghua.edu.cn/git/git-repo -o ~/bin/repo chmod +x 
~/bin/repo

bash 复制代码

git config --global user.email "xxxxxxxx@exmple.com"
git config --global user.name "UserNmae"

mkdir aosp
cd aosp
repo init -u https://mirrors.tuna.tsinghua.edu.cn/git/AOSP/platform/manifest -b android-10.0.0_r41
repo sync

编译

bash 复制代码

source build/envsetup.sh
lunch aosp_x86_64-eng

#亲测j4即可、j16
make -j4

到这里就算编译成功啦

bash 复制代码

emulator -verbose -cores 4 -show-kernel

问题集

1.模拟器启动失败

输入emulator -verbose -cores 4 -show-kernel命令后出现

bash 复制代码

emulator：未找到命令

这种情况大概率是编译环境出了问题，按照上面重新编译一遍即可

Clang编译器崩溃报错

输入make -j16命令后出现

bash 复制代码

clang++: error: unable to execute command: Segmentation fault (core dumped)
clang++: error: clang frontend command failed due to signal (use -v to see invocation)

解决方法：减少并行任务

bash 复制代码

make -j4

文件损坏问题

bash 复制代码

FAILED: ninja: out/soong/build.ninja:1569065: unexpected NUL byte
    descrIption =
                 ^ near here
00:17:56 ninja failed with: exit status 1

解决方法：删除相关文件并重新生成

bash 复制代码

rm -rf out/

# 重新构建系统
source build/envsetup.sh
lunch aosp_x86_64-eng
make -j4
