RvOS

Setting up your machine

You must be running a 64-bit Linux distribution and must have installed some packages to build Paranoid Android. Google recommends using Ubuntu for this and provides instructions for setting up the system (with Ubuntu-specific commands) on the Android Open Source Project website.

Once you have set up your machine according to the instructions by Google, return here and carry on with the rest of the instructions.

Grabbing the source

Repo is a tool provided by Google that simplifies using Git in the context of the Android source.

Installing Repo

# Make a directory where Repo will be stored and add it to the path
mkdir ~/.bin
PATH=~/.bin:$PATH

# Download Repo itself
curl https://storage.googleapis.com/git-repo-downloads/repo > ~/.bin/repo

# Make Repo executable
chmod a+x ~/.bin/repo

Initializing Repo

# Create a directory for the source files
# You can name this directory however you want, just remember to replace
# WORKSPACE with your directory for the rest of this guide.
# This can be located anywhere (as long as the fs is case-sensitive)
mkdir RvOS
cd RvOS

# Install Repo in the created directory
# Use a real name/email combination, if you intend to submit patches
repo init -u https://github.com/RvOS-CLO/manifest -b tiramisu

Downloading the source tree

This is what you will run each time you want to pull in upstream changes. Keep in mind that on your first run, it is expected to take a while as it will download all the required Android source files and their change histories.

# Let Repo take care of all the hard work
#
# The -j# option specifies the number of concurrent download threads to run.
# 4 threads is a good number for most internet connections.
# You may need to adjust this value if you have a particularly slow connection.
repo sync --no-clone-bundle --current-branch --no-tags -j4

Syncing specific projects

In case you are not interested in syncing all the projects, you can specify what projects you do want to sync. This can help if, for example, you want to make a quick change and quickly push it back for review. You should note that this can sometimes cause issues when building if there is a large change that spans across multiple projects.

# Specify one or more projects by either name or path

# For example, enter AOSPA/android_frameworks_base or
# frameworks/base to sync the frameworks/base repository

repo sync PROJECT

Building

The bundled builder tool ./rom-build.sh handles all the building steps for the specified device automatically. As the device value, you just feed it with the device codename (for example, 'beryllium' for the Pocophone F1).

# Go to the root of the source tree...
cd RvOS
# ...and run the builder tool.
./rom-build.sh DEVICE
