ANDROID_SDK 编译

SDK（Software Development Kit，软件开发工具包）是一套为特定软件框架、硬件平台或操作系统提供的开发工具集合，旨在帮助开发者更高效地创建应用程序。

编译环境配置

在PC上安装Ubuntu，进行SDK编译。

硬件：PC满足RAM ≥ 16 GB，CPU core ≥ 4，Hard Drive ≥ 500GB
软件：Ubuntu 22.04，虚拟机磁盘空间分配 ≥ 200GB

配置安装

sudo apt-get update
sudo apt install autoconf bc binfmt-support bison build-essential bzip2
sudo apt install chrpath cmake cpp-aarch64-linux-gnu curl device-tree-compiler diffstat
sudo apt install expat expect expect-dev fakeroot flex

sudo pip install pyelftools
sudo ln -s /usr/bin/python2 /usr/bin/python

获取 SDK 源码

Note

1.SDK不可放在共享目录下编译。
2.编译主机不可用ROOT账号登陆

1.Android SDK 源码下载，release_sdk.sh 脚本下载，通常选择日期后缀最新的文件。

2.存放 tar.gz、md5sum、release_sdk.sh 文件到编译主机同一级目录下。

rk-android13.0-*.tar.gz
rk-android13.0-*.md5sum
release_sdk.sh

3.运行脚本还原 SDK 源码

chmod +x ./release_sdk.sh
./release_sdk.sh

完整编译

1.进入编译主机的代码路径，执行如下命令配置编译目标；

./build.sh lunch

根据板卡型号和SOC选择配置文件。

主板	SOC	配置文件
K1	rk3568	BoardConfig-rk3568-kickpi-k1.mk
K1B	rk3568	BoardConfig-rk3568-kickpi-k1b.mk
K3	rk3562	BoardConfig-rk3562-kickpi-k3.mk
K8	rk3588	BoardConfig-rk3588-kickpi-k8.mk

K1 配置示例：

./build.sh lunch
will lunch sdk

2.完整镜像编译。

./build.sh -AUCKu

单独编译

编译多屏识别镜像

./build.sh -UCKAum

单编Uboot

./build.sh -Uu

单编安卓

./build.sh -Au

单编kernel

./build.sh -CKu

配置 Kernel defconfig

./build.sh -M

常见问题

由于代码位置变化，路径错误导致 android 编译错误?

先清除数据，然后重新编译

source build/envsetup.sh
lunch rk3568_t-userdebug
make clean -j32

编译空间不足？

目前默认线程 -j32，通过降低线程数进行编译，编译方式添加带 -J 线程

如： 修改线程为1，-J1
./build.sh -AUCKu -J1
