Workarounds for building Android 12 on 8GB RAM
Raw
8GB_android-12_compilation-note
Workarounds for building S on 8GB RAM environment:
1. At the start of the build:
[ 99% 138/139] /mnt/ssd/lineage/out/soong/.bootstrap/bin/soong_build /mnt/ssd/lineage/out/soong/build.ninja
This used to take around 30mins, after enabling zram now it takes around 30secs (thanks to @kdrag0n for the zram idea) which is on par with what happens in 16GB RAM building environments
sudo apt install zram-config for installing zram-config package
sudo nano /etc/fstab and add a # in front of the swap disk if you have one and then reboot
After booting cat /proc/swaps to check if zram is enabled or not
2. To avoid issues while building metalava (outOfMemoryException: java heap space)

I don't think so, try searching guide for A13.

Yupp these things are still working just have to increase Java max heap size limit by 1gb more.
