Google has announced ARCore, which brings augmented reality (AR) functionality to Android smartphones starting today. This is great news because you can immediately get started with Google’s developer preview of ARCore, which includes Unreal Engine support!

ARCore enables AR development across Android ecosystem, giving developers the ability to make compelling AR experiences without the need for any additional hardware. 

Today, the ARCore SDK supports the Google Pixel, Pixel XL, and the Samsung Galaxy S8 running Android 7.0 Nougat and above. As the developer preview is refined, Google is adding new devices, with a target of 100 million devices at launch.

We at Epic are working to empower developers to create amazing AR experiences using Unreal Engine, which is gaining deeper AR platform support by the day. Unreal Engine 4.18, coming in mid-October, is shaping up to be a major release for AR, with more mature ARKit support, along with early access support for ARCore.
