ARCore Instant Preview not working

Questions & Answers

Hi :slight_smile:
I have a problem using the Instant Preview (https://developers.google.com/…/deve…/unity/instant-preview…) with ARCore 1.16 and Unity 2018.4.20f1 LTS for Android. If I click play (Smartphone is connected via USB) the errors in the screenshots attached appear, nothing happens on my smartphone. Builds work perfectly.

The PlugIn missing according to the errors is actually there. I tried with another Unity version (2019.3.6f1) same problem. I would like to try it via Wifi, unfortunately therefor i need the Instant Preview App for Android, which should be installed starting the Instant Preview via USB, which is not working as mentioned before.

Would be awesome if smn knows a solution or knows if I can download the Instant Preview App somewhere else (In the PlayStore or when searching on Google I cant find anything) to try it via Wifi

If there is a chance you can upgrade your project to Unity 2019.2 or newer, there is a plugin I wrote to remotely test AR in Editor. It relies on AR Foundation v3.1.3 and supports ARCore.

While the feature-set is very limited (plane detection, camera pose, points cloud) it can greatly assist in the development and debugging of AR applications.
