~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  Wondering whether to use user, userdebug or eng?

  user        The builds that ship to users. Reduced debugability.
  userdebug   High fidelity to user builds but with some debugging options
              enabled. Best suited for performance testing or day-to-day use
              with debugging enabled.
  eng         More debugging options enabled and faster build times, but
              runtime performance tradeoffs. Best suited for day-to-day
              local development when not doing performance testing.

    Solution for AOSP 14 Build Error

    I found the solution. The error occurred due to insufficient memory (16GB of RAM isn't enough). To fix this, you need to create a swapfile on your SSD.

    Here’s how to create a 34GB swapfile:

    1. Check Available Disk Space:

      df -h

    2. Create a 34GB Swapfile:

      sudo fallocate -l 34G /swapfile

      If fallocate is unavailable:

      sudo dd if=/dev/zero of=/swapfile bs=1G count=34

    3. Set Permissions:

      sudo chmod 600 /swapfile

    4. Format as Swap:

      sudo mkswap /swapfile

    5. Activate the Swapfile:

      sudo swapon /swapfile

    6. Verify:

      sudo swapon --show
free -h

    7. Make It Permanent:

      echo '/swapfile none swap sw 0 0' | sudo tee -a /etc/fstab

    Additional Advice

    After setting up the swapfile, it's recommended to

    • delete the existing source,
    • reinitialize the repo - repo init,
    • clone it again,
    • and repo sync -j$(nproc)

    The error looks explicit – you need at least 64GB of RAM to build AOSP AOSP Build Requirements
