一、硬件要求

编译 Android 源码对硬件资源要求较高，推荐配置：

• CPU：8 核及以上（推荐 16 核，支持 AVX 指令集）
• 内存：至少 16GB（推荐 32GB 及以上，避免编译时内存溢出）
• 存储：至少 1TB SSD（源码 + 编译产物约占 150GB+，SSD 可大幅提升编译速度）

二、系统准备及安装依赖

• 建议系统为ubuntu22.04及以上版本
• 安装依赖库

  代码块
  language shell title bash
  sudo apt update && sudo apt upgrade -y sudo apt install -y \ git-core \ gnupg \ flex \ bison \ build-essential \ zip \ curl \ zlib1g-dev \ libc6-dev \ libncurses5-dev \ x11proto-core-dev \ libx11-dev \ libgl1-mesa-dev \ libreadline6-dev \ libglu1-mesa-dev \ g++-multilib \ tofrodos \ python3 \ python3-pip \ python3-setuptools \ libxml2-utils \ xsltproc \ mkisofs \ liblz4-tool \ bc \ rsync \ schedtool \ libssl-dev \ liblzma-dev \ libbz2-dev \ libzstd-dev \ libncursesw5-dev \ pkg-config \ libffi-dev

• 安装Java环境，Android 14 强制要求使用 OpenJDK 17，不兼容其他版本：

  代码块
  language shell title bash
  # 安装OpenJDK 17 apt install -y openjdk-17-jdk openjdk-17-jre # 验证Java版本（输出应包含 "17.x.x"） java -version javac -version

• Ubuntu 22.04 默认已安装 Python 3.10，需确保python命令指向 Python 3

  代码块
  language shell title bash
  # 查看Python版本 python3 --version # 应输出 "Python 3.10.x" # 建立软链接（若python命令未指向python3） ln -s /usr/bin/python3 /usr/bin/python # 安装Python依赖包 pip3 install --upgrade pip pip3 install pycryptodome

• 设置CCACHE，CCACHE 可缓存编译产物，大幅减少二次编译时间：

  代码块
  language shell title bash
  # 安装ccache apt install -y ccache # 配置缓存大小（建议设为50GB，根据磁盘空间调整） ccache -M 50G # 添加环境变量到~/.bashrc（确保每次登录生效） echo 'export USE_CCACHE=1' >> ~/.bashrc echo 'export CCACHE_EXEC=/usr/bin/ccache' >> ~/.bashrc source ~/.bashrc # 立即生效

I. Hardware Requirements

Compiling Android source code requires high hardware resources. Recommended configuration:

• CPU: 8 cores or more (recommended 16 cores, supports AVX instruction set)

• Memory: At least 16GB (recommended 32GB or more to avoid memory overflow during compilation)

• Storage: At least 1TB SSD (source code + build artifacts take about 150GB+, SSD significantly improves compilation speed)

II. System Preparation and Dependency Installation

• Recommended system: Ubuntu 22.04 or higher

• Install dependency libraries:

sudo apt update && sudo apt upgrade -y
sudo apt install -y \
  git-core gnupg flex bison build-essential zip curl zlib1g-dev libc6-dev \
  libncurses5-dev x11proto-core-dev libx11-dev libgl1-mesa-dev \
  libreadline6-dev libglu1-mesa-dev g++-multilib tofrodos python3 \
  python3-pip python3-setuptools libxml2-utils xsltproc mkisofs \
  liblz4-tool bc rsync schedtool libssl-dev liblzma-dev libbz2-dev \
  libzstd-dev libncursesw5-dev pkg-config libffi-dev

• Install Java environment. Android 14 requires OpenJDK 17:

# Install OpenJDK 17
apt install -y openjdk-17-jdk openjdk-17-jre

# Verify Java version (output should contain "17.x.x")
java -version
javac -version

• Ubuntu 22.04 comes with Python 3.10 by default. Ensure python command points to Python 3:

# Check Python version
python3 --version  # Should output "Python 3.10.x"

# Create symlink (if python command doesn't point to python3)
ln -s /usr/bin/python3 /usr/bin/python

# Install Python dependencies
pip3 install --upgrade pip
pip3 install pycryptodome

• Set up CCACHE. CCACHE caches build artifacts, significantly reducing recompilation time:

# Install ccache
apt install -y ccache

# Configure cache size (recommended 50GB)
ccache -M 50G

# Add environment variables to ~/.bashrc
echo 'export USE_CCACHE=1' >> ~/.bashrc
echo 'export CCACHE_EXEC=/usr/bin/ccache' >> ~/.bashrc
source ~/.bashrc
