Android12 编译环境搭建

1. 准备台电脑，编译 Android 对机器要很高，推荐标准配置，避免机器某个导致 Android 编译失败。

最低配置：
• 64 位处理器 16 线程
• 64 位物理内存 16GB（16GB只能使用1线程编译， 2线程或多线程编译会导致内存溢出而编译失败）
• 硬盘 263GB 空闲的磁盘空间

标准配置：
• 64 位处理器 32 线程
• 64 位物理内存 32GB
• 固态硬盘 1TB 空闲的磁盘空间
• 系统：使用 Ubuntu 20.04 操作系统或更高版本

2. 安装依赖。每个人电脑安装软件包不一样，环境搭建也不一样，我们根据 Ubuntu20.04 去安装依赖

使用 lsb_release -a 查看ubuntu 系统版本：

digipro@P510:~$ lsb_release -a
LSB Version:    core-11.1.0ubuntu2-noarch:security-11.1.0ubuntu2-noarch
Distributor ID: Ubuntu
Description:    Ubuntu 20.04.6 LTS
Release:        20.04
Codename:       focal

安装改依赖

sudo apt-get update
sudo apt-get install -y openjdk-8-jdk git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev libgl1-mesa-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev libncurses5 libssl-dev libxml2-utils xsltproc unzip python2 bc imagemagick ccache schedtool libncurses* clang

可能有部分会出错， 例如 Depends: libcurl4 (= 7.68.0-1ubuntu2.20) but 7.68.0-1ubuntu2.19 is to be installed 等等， 我这边就遇到如下问题， 可先忽略。
