3.1 Establishing a Build 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.

Ubuntu 16.04 64bit

   radxa$ apt-get update -y && apt-get install -y openjdk-8-jdk python python-pip git-core gnupg flex bison gperf build-essential \\

          zip curl liblz4-tool zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 \\

          lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev ccache \\

          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 lzop rsync

   radxa$ pip install pycrypto

Configure 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

3.2 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 -k

   radxa$ sudo cp /tmp/repo /usr/local/bin/repo

   radxa$ sudo chmod +x /usr/local/bin/repo

3.3 Get source

export GIT_SSL_NO_VERIFY=1

git config --global user.email "[e-mail]"

git config --global user.name "Your Name"

radxa:rockpi4-android9$ repo init -u https://github.com/radxa/manifests.git -b rockpi-box-9.0 -m rockpi-release.xml

   radxa:rockpi4-android9$ repo sync -d --no-tags

添加环境变量

sudo vi /etc/enviroment

JAVA_HOME=”/usr/lib/jvm/java-8-openjdk-amd64”

PATH=”$JAVA_HOME/bin:$PATH”

CLASSPATH=”$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar”

SSL_CERT_DIR=”/etc/ssl/certs”

4.3 Building AOSP

$ source build/envsetup.sh

$ lunch rk3399-userdebug

# build Android TV
