To get started with Android/LineageOS, you'll need to get familiar with Repo and Version Control with Git.

To initialize your local repository using the LineageOS trees, use a command like this:

repo init -u git://github.com/LineageOS/android.git -b lineage-17.1

Add anbox manifest:

wget https://raw.githubusercontent.com/Anbox-halium/anbox-halium/lineage-17.1/anbox.xml -P .repo/local_manifests/

Then to sync up:

repo sync

Then to apply anbox patches:

anbox-patches/apply-patches.sh --mb

Please see the LineageOS Wiki for building environment setup.

To build anbox:

. build/envsetup.sh
lunch lineage_anbox_arm64-userdebug
make systemimage -j$(nproc --all)
make vendorimage -j$(nproc --all)

Execute command blew:

wget -O - https://github.com/Anbox-halium/anbox-halium/raw/lineage-17.1/scripts/install.sh | bash

Note: Run installer on the user you are willing to install anbox on

Running anbox requires:

• Veth for networking
• Ashmem
• Specific binder nodes (anbox-binder anbox-hwbinder anbox-vndbinder) Checkout defconfig kernel patcher script for patching halium devices kernel.

check-kernel-config.sh halium_device_defconfig -w 

On mainline devices it is highly recommanded to use needed drivers as module. (binder_linux and ashmem_linux)
