ROCK Pi 4 > Android7
Recommend build host is Ubuntu 16.04 64bit, for other hosts, refer official Android documents Establishing a Build Environment.
Repo
radxa$ wget 'https://storage.googleapis.com/git-repo-downloads/repo' -P /tmp/ radxa$ sudo cp /tmp/repo /usr/local/bin/repo radxa$ sudo chmod +x /usr/local/bin/repo
In China Download Repo:
radxa$ echo "export REPO_URL='https://mirrors.tuna.tsinghua.edu.cn/git/git-repo/'" >> ~/.bashrc radxa$ source ~/.bashrc radxa$ curl https://mirrors.tuna.tsinghua.edu.cn/git/git-repo -o /tmp/repo radxa$ sudo cp /tmp/repo /usr/local/bin/repo radxa$ sudo chmod +x /usr/local/bin/repo
Init Environment
Android's source code primarily consists of Java, C++, and XML files.
To compile the source code, you'll need to install OpenJDK 8, GNU C and C++ compilers, XML parsing libraries, ImageMagick, and several other related packages.
radxa$ apt-get update -y && apt-get install -y openjdk-8-jdk python git-core gnupg flex bison gperf build-essential \
zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 \

libgl1-mesa-dev libxml2-utils xsltproc unzip mtools u-boot-tools \
htop iotop sysstat iftop pigz bc device-tree-compiler lunzip \
dosfstools vim-common parted udev
Configure the JAVA environment
radxa$ export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64 radxa$ export PATH=$JAVA_HOME/bin:$PATH radxa$ export CLASSPATH=.:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar

RUN which repo
ENV REPO_URL='https://mirrors.tuna.tsinghua.edu.cn/git/git-repo/' USER=android7-docker
ARG USER_ID=0
ARG GROUP_ID=0
RUN groupadd -g ${GROUP_ID} jenkins-docker && useradd -m -g jenkins-docker -u ${USER_ID} android7-docker
USER android7-docker
Build DockerFile
radxa$ docker build -t android-builder:7.x --build-arg USER_ID=`id -u` --build-arg GROUP_ID=`id -g` $(which-dir-dockerfile-in)
Download source code
radxa$ mkdir rockpi4-android7 radxa$ cd rockpi4-android7
Then run:
radxa$ repo init -u https://github.com/radxa/manifests -b rk3399-all-7.1 -m rk3399_n_all_release.xml radxa$ repo sync -d --no-tags -j4
It might take quite a bit of time to fetch the entire AOSP source code(around 86G)!
Build u-boot
radxa$ cd u-boot radxa$ ./make.sh rock-pi-4b-rk3399 radxa$ cd ..
The generated images are **rk3399_loader_v_xxx.bin** , **idbloader.img** and **uboot.img**
Building kernel
For DSI 480P, support Raspberry Pi official 7" Display.
radxa$ cd kernel radxa$ make rockchip_defconfig radxa$ make rk3399-rockpi-4b.img -j$(nproc) radxa$ cd ..
For HDMI 4K
radxa$ cd kernel radxa$ make rockchip_defconfig radxa$ make rk3399-rockpi-4b-hdmi.img -j$(nproc) radxa$ cd ..
The generated images are **kernel.img** and **resource.img**:
- kernel.img, kernel with rkcrc checksum
- resource.img, contains dtb and boot logo, Rockchip format resource package
Building AOSP
radxa$ source build/envsetup.sh radxa$ lunch rk3399_all-userdebug radxa$ make -j$(nproc)
It takes a long time, take a break and wait...
Generate images
radxa$ ln -s RKTools/linux/Linux_Pack_Firmware/rockdev/ rockdev radxa$ ./mkimage.sh
The generated images under rockdev/Image are
├── boot.img ├── idbloader.img ├── kernel.img ├── MiniLoaderAll.bin ├── misc.img ├── parameter.txt ├── pcba_small_misc.img ├── pcba_whole_misc.img ├── recovery.img ├── resource.img ├── system.img ├── trust.img └── uboot.img
Generated RkUpdate Image
radxa$ cd rockdev radxa$ ln -s Image-rk3399_all Image radxa$ ./mkupdate.sh
The images under rockdev/ are `update.img`
Generated GPT Image
radxa$ cd rockdev radxa$ ln -s Image-rk3399_all Image radxa$ ./android-gpt.sh

The images under rockdev/Image are `gpt.img`
Installation
GPT Image Install on eMMC module
RkUpdate Image Install on eMMC module
There may be some performance loss when using microSD.
