AxionOS

Getting Started

To get started with AxionOS, you'll need to be familiar with Source Control Tools.

Initializing the Source

Initialize your local repository using the AxionOS manifest:

repo init -u https://github.com/AxionAOSP/android.git -b lineage-22.1 --git-lfs

Then sync the source:

repo sync

Build Environment Setup

Make sure your build environment is properly set up by following the LineageOS build guide.

Before building, configure the environment:

. build/envsetup.sh

Device Flags

Modify your device trees to inherit LineageOS common settings and disable EPPE (if applicable):

TARGET_DISABLE_EPPE := true
$(call inherit-product, vendor/lineage/config/common_full_phone.mk)

AxionOS-Specific Flags

These flags are needed for About Phone section UI and GMS framework.

📷 Camera Flags

# Define rear camera specs (multiple sensors supported)
AXION_CAMERA_REAR_INFO := 50,48  # Example: 50MP + 48MP

# Define front camera specs
AXION_CAMERA_FRONT_INFO := 42  # Example: 42MP

👤 Device Maintainer & Processor Info Flags

# Maintainer name (use "_" for spaces, e.g., "rmp_22" → "rmp 22" in UI)
AXION_MAINTAINER := rmp

# Processor name (use "_" for spaces)
AXION_PROCESSOR := Snapdragon_CPU_1

🔧 Build Variant Flags

By default, GMS (Google Mobile Services) is enabled. To disable it, set it to MICROG/VANILLA:

AXION_BUILD_VARIANT := MICROG/GMS/VANILLA

Building AxionOS

🔑 Generate Private Keys

Before building, generate private keys:

gk -s

📲 Lunch Command

Set up the build environment for your device:

axion <device_codename>

🔄 Syncing Source

After setting up the build environment and syncing the whole source, easily sync the latest source changes with:

axionSync

⚙️ Build for Fastboot Flashing (fastboot flashall)

Compile the ROM with:

ax -j<count>

Replace <count> with the number of CPU threads for faster compilation (e.g., ax -j16).

📜 Credits

AxionOS is built upon the hard work of the Android Open Source Project (AOSP) and LineageOS teams. Special thanks to all contributors!

🚀 Happy Building!
