PureAOSP

Android Platform Manifest for Building Pure Android

PureAOSP is a free and Open-source unmodified Android OS also known as Pure Android with Upstream Linux Kernel.
This repository is aimed for reducing AOSP Source Code's filesize for my personal PureAOSP project.
Remove unused Android Git repositories. Example: device trees, kernel trees, prebuilts, system packages and etc..
You can use this PureAOSP manifest repository if you need AOSP Android Platform Sources.

To get started with PureAOSP sources to build Android system image, you'll need to get familiar with Git and Repo.

To initialize your local repository using the PureAOSP trees to build Android system image:

   repo init -u https://github.com/zawzaww/aosp-android.git -b android-11.0.0

(OR)

To initialize a shallow clone, which will save even more space, use a command like this:

   repo init --depth=1 -u https://github.com/zawzaww/aosp-android.git -b android-11.0.0

Then to downloading the sources:

   repo sync

(OR)

Additionally, you can define the number of parallel download repo should do:

   repo sync -jN -f --force-sync --no-clone-bundle --no-tags

You can type this:

   repo sync  -f --force-sync --no-clone-bundle --no-tags -j$(nproc --all)

After syncing is done, use these commands to build:

cd <source-dir>

. build/envsetup.sh

lunch <device_name>

make -j4 (OR) make -j$(nproc --all)

For make -jN command

Official AOSP Docs: Build everything with GNU make can handle parallel tasks with a -jN argument and it's common to use a number of tasks N that's between 1 and 2 times the number of hardware threads on the computer being used for the build. For example, on a dual-E5520 machine (2 CPUs, 4 cores per CPU, 2 threads per core), the fastest builds are made with commands between make -j16 and make -j32.
