Can't get ARCore session to start

mickeyvanolst · October 9, 2021, 4:31am

So far I’ve tried this with SDK versions 24, 26, 29, 30, and UE4.26.2 and 4.27

I’m simply running the default example project for AR using Android. I’ve verified my phone is able to run ARCore.

I’m able to compile the app and install it on my phone, after starting it I get presented with the button asking me to scan my environment. An overlay appears and I give permission for the app to use the camera.

The camera image never appears, the app doesn’t respond and crashes continuously after that. Here is the feedback I get from the console:

I’ve searched on most internet pages I could find about people having issues with Unreal and ARCore, though I can’t find anyone with the exact same issue.

It seems to me that somehow there’s a bug in the ARCore plugin that doesn’t properly register the permission given to use the camera, even though the permission is granted.

I’m kind of running out of ideas, does anyone have any points for me how to move forward?

Kind regards and thanks,
Mickey

Can you post some extra info? Which brand+model device(s) have you tested on? Do your SDK/NDK settings have the full path (project settings>Platforms>Android SDK)? Can you launch your project on your device from the editor directly?

I just dug up and tested (on my S20FE) an AR project (4.25) configured using the nVidia method; jdk1.8.0_77, android-ndk-r21e, installed in C:/NVPACK/

Jain93 · October 11, 2021, 11:28pm

I have the same problem and I also make different combinations of SDK and NDK, but I have no progress from the welcome page of the template, I have tried it with different computers and different devices (Samsung s21 ultra and s20) but none progresses; I was only able to get it to work once and what I did was change the quality from realistic to scalable 2d; Maybe it will work for you, however it did not work again for me and I could not compile and I really want to develop in AR with ArCore and Unreal.

PD: I have a post in the forums, but I have not had answers, hopefully you will
Problem running AR Handheld in UE4.27 ARCore - UE4 AnswerHub (unrealengine.com)

VictorLerp · October 12, 2021, 4:46pm

We just released 4.27.1 which fixed ARCore not working on Android 11. Download the update and try the HandHeld AR Template

wickerman123 · October 12, 2021, 8:51pm

Have you been able to verify this? I’m still getting the exact same issue as before the hotfix. This is with a fresh installation of Android Studio 4.0 and a fresh copy of the Handheld AR Template.

Yes, but I can’t verify if you’re having the same problem.

I’v updated to 4.27.1, but the issue remains the same

If you’re still having this issue, make sure you target android SDK version 24 and check “Support Arm64” in project settings

Jain93 · November 2, 2021, 11:47pm

when i do that, the editor show this messages

I have the same issue with this as well, I have an android 11 phone.

anonymous_user_7f28b442 · November 18, 2021, 3:39am

I stuck in this screen, it just doesnt allow me to scan at all

jyashi · November 18, 2021, 10:01am

Thats a problem because Google forces you to target SDK 30 from November onwards so we need to target Min 30…

jyashi · November 18, 2021, 10:06am

Anyone got a solution to this? For me AR works TILL SDK 29… but as soon as i do SDK 30 it throws either a descriptor file not found error or if you implement it in a different project it just does not show the camera feed to scan…

We need to target SDK 30 for Google play store… Come on Unreal… I don’t want to start up a fresh Flutter project just for the AR feature …

Jain93 · November 19, 2021, 4:59pm

This is what worked for me, and with this all my projects have been executed properly, on all my devices (s21-ultra and s20).

in unreal

in android studio

VictorLerp · November 23, 2021, 4:52pm

SDK Level 30 requires ARCore version 1.25 or higher. 4.27 is currently on ARCore version 1.22, but we’re working on updating ARCore to version 1.26 in UE 5.0. There are API-changes between 1.22 and newer versions of ARCore that prevent us from doing another version update in a hotfix, unfortunately.

jyashi · November 25, 2021, 5:09am

Thanks for the update.

It would be great if this info was on the unreal docs AR page so others wouldn’t be as lost as me.

Thanks again.

Aldebahran_1 · December 12, 2021, 8:51pm

Hi all,
Sorry of my english
I think I have solved the problem of stucking in start menu. (S20+)
By unchecking in project settings/platform/android/build “support armv7” and check "support armv64

Tell me if this work on other devices
Thank you.

JayChang-zhe · February 25, 2022, 4:50am

Hey, is it possible to fixed the bug that re-start AR Session after “Stop AR Session” ? Right now the re- start AR Session can’t use the camera directly

21shabutie13 · May 13, 2022, 1:18pm

Found a fix for this that resolved the issue on my end. Remove or comment-out Line 81(r.OpenGL.ForceDXC=0) from the DefaultEngine.ini in your project (or in the HandheldAR template before creating a new project). Also, disable Vulkan, as ARCore does not support Vulkan yet.

This fixed the issue on my end. This is slated to be fixed in UE 5.0.2 which should be released around the end of May.

Code_Reaper · July 20, 2022, 2:22am

I started working with UE 5.0.3 and was trying to figure out why the call to Start AR Session didn’t do anything. This response is what led me to my answer. In the latest editor the project setting, “Platforms->Android->Build->Support Vulkan”, must be turned off or you will not be able to use the AR functions. This is as of 7/19/2022.
