Export XR site to Oculus Mobile APK

This guide explains how to package your XR site with the Exokit Engine as an APK for Oculus Mobile (Oculus Go, Oculus Quest) devices.

Set default site

In the Exokit main.cpp is where you will find the default site that the Exokit APK will load into. Change the jsString to your site URL or file path.

OPTION 1- Docker

The upside of docker is that it requires minimal environment setup. The downside is that it will do every instruction everytime it is run.

Building an APK with the Dockerfile is as simple as:

  • docker pull debian:latest
  • docker build -f android.Dockerfile -t exokit .
  • docker run exokit cat exokit.apk >exokit.apk

OPTION 2- Manual environment setup


Node 11.15.0
Latest Exokit
Ubuntu Windows Subsystem for Linux (WSL)

Install Android sdkmanager

Instructions for getting the Android SDK manager, adb, ndk-bundle, etc:

To install it on a Debian-based system, simply do:

# Install latest JDK
sudo apt install default-jdk

# install unzip if not installed yet
sudo apt install unzip

# get latest sdk tools - link will change. go to https://developer.android.com/studio/#downloads to get the latest one
cd ~
wget https://dl.google.com/android/repository/sdk-tools-linux-4333796.zip

# unpack archive
unzip sdk-tools-linux-4333796.zip

rm sdk-tools-linux-4333796.zip

mkdir android-sdk
mv tools android-sdk/tools

Then add the Android SDK to your PATH: open ~/.bashrc in editor and add the following lines into the file:

# Export the Android SDK path
export ANDROID_HOME=$HOME/android-sdk
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools

# Fixes sdkmanager error with java versions higher than java 8
export JAVA_OPTS='-XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee'


source ~/.bashrc

Show all available SDK packages:

sdkmanager --list

Accept all sdkmanager licenses:

yes | $ANDROID_HOME/tools/bin/sdkmanager --licenses

Identify latest android platform (here it’s 28) and run:

sdkmanager "platform-tools" "platforms;android-28"

Now you have adb, fastboot and the latest sdk tools installed.

To install NDK directly, run:

sdkmanager "ndk-bundle"

Build APK

Confirm that $ANDROID_HOME points to Android/Sdk directory

Make the NDK standalone toolchain:

cd exokit

Build the APK:

# Run this inside Ubuntu WSL

If you want to now install and run in your plugged-in device using adb:
