</code>

==== 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.
<code bash>
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
</code>
Configure the JAVA environment
<code bash>
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
</code>

Build DockerFile
<code>
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 ====
<code bash>
radxa$ mkdir rockpi4-android7-tv
radxa$ cd rockpi4-android7-tv
</code>
Then run:
<code bash>
radxa$ repo init -u https://github.com/radxa/rockpi4-android-tv-7.1.git -m rockchip_tv_nougat_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)!

<code bash>
radxa$ cd u-boot
radxa$ make rock-pi-4b-rk3399_defconfig
radxa$ ./mk-uboot.sh

The generated images are **rk3399_loader_v_xxx.bin** , **idbloader.img** and **uboot.img**

<code bash>
radxa$ cd kernel
radxa$ make rockchip_defconfig
radxa$ make rk3399-rockpi-4b.img -j$(nproc)

The generated images are **kernel.img** and **resource.img**:
