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 \

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

Build DockerFile
radxa$ docker build -t android-builder:8.x --build-arg USER_ID=`id -u` --build-arg GROUP_ID=`id -g` $(which-dir-dockerfile-in)
Download source code
radxa$ mkdir rockpi-n10-android8 radxa$ cd rockpi-n10-android8
Then run:
radxa$ repo init -u https://github.com/radxa/manifests.git -b rk3399pro-android-8.1 -m rk3399pro-rk-vendor-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 rk3399pro_dual radxa$ cd ..
The generated images are **rk3399_loader_v_xxx.bin** , **idbloader.img** and **uboot.img**
Building kernel
For HDMI 4K
radxa$ cd kernel radxa$ make rockchip_defconfig radxa$ make rk3399pro-rockpi-n10-android.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
Android Tablet:
radxa$ source build/envsetup.sh radxa$ lunch rk3399pro-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 ota
