Get started with targeting your ARCore Unity apps to Android.
This guide shows you how to set up your development environment and try out an ARCore sample app.
An ARCore supported device
A USB cable to connect your device to your development machine
Make sure to include Android Build Support during installation
The Universal Render Pipeline (formerly known as Ligthweight Render Pipeline or LWRP) is not supported by the ARCore SDK for Unity
When using Unity 2019, the following Unity packages are required:
