Any updates on when ArCore is getting released ? Any one ?
Is it possible to subscribe to changes in camera position using session class?
Would like any information on this as well.
I use Pixel XL (Android 8.0) to run.
It show error log.
My Android Studio had been reinstalled ,so I thought Android Studio SDK was ok.
Other Settings`s settings as same as [https://developers.google.com/ar/develop/unity/getting-started]
Use this for works on S8 Plus !
Just one file to change.
It works for me
I've just updated to Unity last official version: 2017.2
I don't want any of the VR features, and I intend to build in the lowest Android SDK version: 16 (4.1 Jelly Bean), but I can't because it gets messed up with tango library. The Error:
Temp/StagingArea/android-libraries/libtango_3d_reconstruction_api/AndroidManifest.xml as the library might be using APIs not available in 16
The suggestions provided are:
Suggestion: use a compatible library with a minSdk of at most 16,
or increase this project's minSdk version to at least 19,
or use toolsverrideLibrary="com.projecttango.tangosupport" to force usage (may lead to runtime failures)
I tried the second, but it doesn't work. With the first, it works, but what I really want is to disable this library to get included or involved on the apk, so I can build with 16 SDK version, not 19.
once a plane is detected whats the best way to extend it to several metres to give you several flat metres to play on without the plane visualiser then showing?
Very happy to share ARCore version of Sahi Labs
I'm trying to run the HelloAR scene on a Pixel 2 following this guide but the app keeps crashing (built with Unity 2017.2.0f3)
I'm running HelloAR scene and the only thing that doesn't work is the camera feed as the background. As I understand it that should be a feature within the HelloAR example scene. The app only displays the camera background blue color. I can see feature points and the app will cover found-planes with the plane triangle texture asset. But no camera feed. How come the camera feed isn't working for me? Does the HelloAR example scene need additional features implemented?
Here's my check list:
PC OS: Windows 10 Pro
Unity Version: 2017.2.0b9
Android SDK Build Tools:* Updated to 27.0.1
Android SDK Platform Tools: 26.0.2
Android SDK Platform:* Updated to 27
Android SDK Tools: 25.2.5
JDK Version: 8.0.510.16
Development Test Device:
Phone Model: Pixel
Phone Android Version: 7.1.2
Can confirm I gave the test app and arcore service camera permissions.
Edit: After hookin' up to logcatz I'm consistently getting this error:

You may need to manually give the app permission to access the camera. Happened to me as well. The permissions popup dialog doesn't seem to work with the latest set of tools for some reason.
I forgot to write that but yes. The installed app and arcore service have camera permissions. I'm working on getting logs.
Do Google and/or Unity have any plans for updating the ARCore plugin for Unity? The current preview of ARCore for Unity have been out for 3 months almost, without any significant updates. I sure hope it's not abandoned, because we have plenty of good ideas to try using ARCore. Are there any updates coming in the near future?
Thanks a lot in advance.
@timmunity Would love any information as well!
@Flarup During the keynote speech in Unite Austin they said this was going to change a lot over the coming months. I bet they're mid development of a pretty big update/change to the plugin.
Came back to this 2 weeks later and it automagically works.
Only things that changed is that I'm using Unity 2017.3.0.b10 and re-downloaded the ar core unity package just in case that updated to.
Does anyone have any ideas on how to initialize/shutdown/reset ARCore properly? I thought loading a scene that didn't use any ARCore components might clear out any ARCore necessary instances and then I could load an ARCore scene again and have it initialize properly but that is not the case.
Thanks for any advice.
There's a comment in the plugin code that you can't actually "connect" to an ARCore session twice in the same application lifetime, and that this is understood as a limitation that's going to be fixed. Based on my own experiments I've sort of felt like I just need to live with that limitation for now and pray it won't exist when ARCore goes 1.0. If you really, really must work around it I would suggest parenting all ARCore related stuff to an object with DontDestroyOnLoad enabled, then enable / disable it when going in and out of AR. You may need to re-initialize things because all of the pre-existing planes and such will still be there. I had too much trouble with this re-initialization process and decided to spend my time elsewhere.
I'm having trouble getting an ARCore-enabled game to work with Gradle builds. It's an ARCore mode impelmented in a much bigger non-AR game, which has recently hit the dex limit that forces us to use Gradle instead of the internal build process. Unfortunately, when entering AR mode I get the DllNotFoundException that's a symptom of not having the ARCore preview SDK installed:
I have installed the ARCore preview SDK, and this issue does not happen with "Interal" builds, only Gradle ones.
I posted about the issue here and was told it's probably a Unity issue.
My suspicion is that it's a gradle configuration issue. I've been trying to add dependencies to "tango_client_api2" and "arcore_client", along with including the "arcore_client.aar" lib that's available here (https://github.com/google-ar/arcore-android-sdk) but to no avail. I'm pretty stumped here. I'm fully comfortable with shipping the game with the tango libs it needs, for the short term I'll basically do anything to get it working. It's very annoying to have to switch to a "prototype" branch where I've stripped out a lot of critical android libs to get below the dex limit just so AR mode will work.
hey guys... i am about to cry here! i have tried everything and i am stuck in the 'build and run' step. =/
it seems that the are some manifest confusion in my mac.
(i am using osx, S8 with 7.0 android, unity 2017.3, android studio updated today)

Is there a way I could sim all of this on a computer before pushing it to the phone.. It would help with the debug process.
Hello all and @timmunity
Is there a way to stop searching for more tracking planes, after the first tracking plane have been found?
Basically, I just want a single plane to build on, and once that have been found I don't want any additional planes to show up. I can easily disable rendering of additional planes, but the problem is that they still exist in the ARCore session and will by hit by raycasts.
I'm using ARCore preview 2. Thank you very much in advance for your help.
I'm stuck on this for quite some time now. When I use SessionComponent, I need to pass a Camera object for m_firstPersonCamera in the script and it is this camera that will have the background webcam feed rendering. All good till now. But what if I need to render the background to a RenderTexture and to the screen as well ? I cannot even use another camera ( one for rendering on screen and one for rendering on Render Texture). Since there can be only one session component and it only takes one camera object (where it renders the background), I cannot get the rendering data on a RenderTexture. Is their a way to achieve this ? Rendering both on screen and Render Texture ?
I'm pretty sure the HelloAR demo polls for new planes every frame using Frame.GetNewPlanes(ref mNewPlanes) - in our own version we move away from this polling once a plane has been interacted with in some way. Not had any issues like what you describing with regards to them still appearing.
Is there a known issue with no camera permission being requested? Using Unity 2017.3f3, with or without permissions forcibly added to the manifest, the resulting app is not request camera permission, and subsequently ARCore is failing on load, and crashing out.
Builds have also been tested out of Unity 2017.2, and 2017.1. Despite having this working a month ago (I have since updated the ARCore plugin from the google developer site), it no longer functions even on a clean project.
Update - Now the plugin is version 2, it also means the google AR Core preview (that is installed separately) also needs to be updated. I was running a month old version of that other app.
If anyone is having this issue:
Then that means you installed arcore-preview2.apk (the latest version) onto your device. Tango related classes are only in the older arcore-preview.apk (the firstversion). So, the errors you are getting are telling you exactly that -- there are no Tango Api related classes in arcore-preview2.
If you REALLY are determined to run an app running the older arcore-preview, then downgrade to arcore-preview.apk and install it on your phone. This will REPLACE arcore-preview2.apk on your device (remember to install preview2 again if you wish to use the latest arcore features).
Honestly, I recommend using the latest if at all possible and update your project to the latest arcore preview.
I'm an absolute beginner and was confused about this install- Do you use Android Studio for that install process? Or is it just a command line with the phone connected+ USB debugging enabled?
Have you find a solution? I'm having this same issue when I build with "Development build" disabled. When enabled it works properly.
I am checking the Java api has much more methods than the Unity api
How do i access the Virtual positioning service? I dont see any method for it
I am testing ARCore for the first time. I am using Unity and have setup all the necessary stuff.
I am using the following SDK (but I did try all the higher versions also)
Get a popup on phone stating ARCore "stopped working"; this is what I see if i view the log:
I reviewed the list of devices supported, which I have hlited mine:
Any ideas? Is Note 8 actually supported yet?
Thanks in advance!
Could I change the ARCore camera matrix information before rendering?
How we can find and set true heading in arcore scene? In ARkit Unity AR aligment gravity and heading option is available. Is there any way to implement this in ARCore?
I am trying to put AR object in my game scene on the base of it's GPS location in real world and also launch the app in the direction user is facing in the real world. But the problem is the object starts to place in direction of camera and not the direction in which user is facing. So how to apply true heading rotation to camera in ARCORE and place object in Scene.

project available for download anywhere?
Has anyone else had issues with ARCore and the latest Android OS... I have been working on an ARCore project which was working fine, however after upgrading my Android OS for my S8 last week and now cannot get ARCore working?
Now every scene in my project that utilizes ARCore crashes.
Is anyone else experiencing this?
I am using Android SDK v8.0 OREO and Java Development Kit V8.0_162. Anything newer crashed on me during builds.
There is a rendering issue in ARCore. I need a landscape oriented scene in ARCore. I worked on an example scene in ARCore sdk. I changed the orientation to landscape left. I just put a game object 1m in front the camera. When I run the project everything works fine. But what my problem is, at first the game object renders in portrait mode, then it changes its orientation to landscape mode. Which means there is a flickering on game object in orientation when starting. I think this happens from ARCore itself. That is not good to go. Kindly help me to fix this issue if you can. Any help is appreciated. And thanks in advanced.
Have you got the solution to fix this. If it is please share it. Thank you.
I haven't got the fix for it but I can no longer reproduce the same. Updating ArCore would have fixed it I assume
I'm trying to understand how the `Tracked Pose Driver` works along with ArCore. All the example scenes of ArCore have this component attached and everywhere the `Update Type` of this component is set to `Before Render`. When I make a build with this setting I see my GameObjects a little jittery, i.e. they don't seem to stick to one single spot but keep moving by a very small distance and quite frequently. In other case, when I set `Update Type` to `Update And Before Render` , my GameObjects look very smooth, i.e they stick to one single spot and I hardly notice any position change there. The documentation here https://docs.unity3d.com/ScriptRefe...eDriver.UpdateType.UpdateAndBeforeRender.html is not helping enough. Can somebody from Unity help explain what is going on in background with `Tracked Pose Driver` and also why are the example scenes not using `Update and Before Render`
Will it work on a Tribute 5 Android phone?
Here is the list of supported devices: https://developers.google.com/ar/discover/supported-devices
I don't see the Tribute 5 there, but Google also add new devices over time.
I want to change detected plane of arcore
in arcore generated plane is not perfect square or rectangle,it has no definite shape
i want generated plane should be rectangle or sqaure like this i mean with definite shape
Hey guys, Is there any way to adjust camera settings like exposure within unity? i dont want the phone camera adjust light/brightness by itself. its really bad for my app and i'd like to have control over it by myself. I know we can do it out of unity. But I cant write plugins. if there is no way, then how can I request it to unity team?
PS: also focusing in the area that i tapped is another useful thing to have access.
I would need exactly the same feature - there is no way to see anything near window as whole camera image from the inside goes black as it focuses on exterior.
Let me know if you found anything @asa989
I havent found anything yet. also camera image wont work in lightweight render pipeline!!
Hello, Arcore is supported in Samnsung Galaxy A7 (2018)?
This is the official list: https://developers.google.com/ar/discover/supported-devices
I use Unity 2018.3.2f1, the latest arcore unity package.Build the apk & install on my phone(Hwawei- RNE-AL00).
When I run the HelloAR app it say "ARCore encountered a problem connecting.Please start the app again".
Is the reason that my phone does not support the arcore?
Or is there any other issue?
