Android Build

Yeah, that's about it...
Just whatever I use to build Android for my phones with.

Setup

1. Ensure you are running a semi-recent Windows 11 version (using IoT LTSC 2024 in this case)

2. Enable WSL, Hyper-V, Windows Hypervisor Platform, and Virtual Machine Platform (will require a restart)

3. Install Ubuntu 22.04.3 from the Microsoft Store

4. Run the Ubuntu-22.04.3 App from the Start Menu and configure it

5. Create a .wslconfig folder in your User folder and add this code (specific to my CPU, adjust based on your specs):

   [wsl2]
   memory=48GB
   processors=12
   swap=32GB

6. Terminate WSL and open it again:

   wsl --terminate Ubuntu-22.04.3

7. Update the Ubuntu WSL instance:

   sudo apt update
   sudo apt upgrade

8. Install the dependencies:

   sudo apt-get install git-core gnupg flex bison build-essential zip curl zlib1g-dev libc6-dev-i386 \
   x11proto-core-dev libx11-dev lib32z1-dev libgl1-mesa-dev libxml2-utils xsltproc unzip fontconfig \
   python-is-python3 repo git-lfs libssl-dev

9. Download and replace the repo applet in /usr/bin from here
   (needed to avoid git-lfs errors because the repo binary version that the deb ships is horribly outdated)

Building

1. Create your working directory on the VHDX (I would suggest using your WSL user's /home directory)

2. Set up repo / git:

   git config --global user.name [your user]
   git config --global user.email [your email]
   repo init -u https://github.com/PixelOS-AOSP/manifest.git -b fourteen --git-lfs

3. Create the local_manifests folder in the .repo directory and place the roomservice.xml in it:

   cd .repo
   git clone https://github.com/legofanlovessayori/android_build.git local_manifests

4. Initiate the source download:

   repo sync --force-sync --optimized-fetch -j `nproc`

5. Run the product configuration:

   . build/envsetup.sh
   lunch aosp_a71-ap2a-[buildtype]

6. Start the build:
