Workarounds for building Android 12 on 8GB RAM

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)

Im at the file. Am i adding code.

Yes, go here verNANDo57/android_build_soong@ffc8846, copy the contents of the file in the link. Also, are you using a gui or just cli?

Window manager simular to i3 but built for mouse and has some functions simular to desktop. Distro arch linux.

I know how to use the command line. So no problem. But i also have vim and a light weight gui text editor.

Also where exaxtly are the xontents being pasted to. In which spot.

So, search the file for cmd.BuildTool, and replace it and some lines after it with the edited version.

I found the cmd.buildtool. Where do I stop pasting at.

I see where the metalava stops but do you think I should add the lint lines to?

Add Flag("-J-Xmx6114m") under Flag(config.JavacVmFlags)

Add Flag("-J-Xmx6114m") under Flag(config.JavacVmFlags)

Its already there

All right, so just try to build it and see (I think the error from before is because the modified version mentioned in the post is based on lineage os and it is different from aosp.

Aicp uses lineage base and tosses out what it doesnt use when it comes to its own base. Its in the default.config
It regenerated but the whent back way way back. Its gonna be a whole what the heck happened.

Perhaps your computer is not powerful enough to perform this task. A lot depends not only on the memory size, but also on the PC configuration. Anyway, if it freezes, that doesn't mean that it won't unfreeze, you should just wait.

I faced the same problems when I had slow samsung laptop (RC530), it always froze on metalava. I always had to wait for about a hour or two. Just try doing what I did back then, if it doesn't help that means something is wrong with sources.

Good luck!

Your configurtion worked. I finally got past the meta lava. Build is almost done.

Hello I creatin lineageos 19.0 but ı 8gb ram wit build rom but lineage/out/soong/.bootstrap/bin/soong_build /mnt/ssd/lineage/out/soong/build.ninja ı can't pass, even it take my time, ı looked at what was said here, but you did not understand anything, can you help me please.

If you have 8gb of ram, i recommend at least a 24gb swapfile.

(you can Google how to add one)

How do i do it?

hello ı have 8gb ram and 27gb swap but not build android.

And eşit but close terminal

Hello how do create cmd.BuildTool

Its already there you have to change the heap. Lineage is currently combing to files into one. I post later. What your gonna do is change the value on every of heap. Once you do this it will build.

will this work for android 13?

will this work for android 13?

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

will this work for android 13?

WELL my friend built los 20 with 8gb ram + 36gb zram (fedora)

will this work for android 13?

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.
