Adding the resolution of this issue here for others with the same issue.


For most developers that recently upgraded to Spaces 0.11.1 the resolution is to: 


  1. Uninstall Spaces Services and the Samples app
  2. Power off the device
  3. Power it back on again
  4. Reinstall services
  5. Reinstall the samples app
  6. Grant permissions to both


You might also need to check if your Motorola Edge and A3 firmware is up to date. Here are the current firmware versions (as of 03/24/2023):

  • Motorola Edge: S3SHS32.12-41-4-4
  • A3: A3_user_S1040001_2208180059_sdm710_postcs8
  • Lenovo UDC: 22.09.0.43

You can check your A3 version in the Lenovo Universal Device Client app and your Motorola Edge version under Settings > System updates .


If you cant update you might need to factory reset your device.

I have also been trying the Spatial Mapping sample as well as a custom app with spatial mapping enabled.  I have not been able to get the mesh visualization to work.  I am using AR Foundation 4.2.7 and have latest Spaces Service APK and SDK installed (0.11.1).  

After installing the latest Spaces Services, please try restarting the phone to verify that the new OpenXR instance is properly set up and running, and that the Camera permission has been set in the Services apk and the app.

I have tried restarting the device as well as confirmed Camera Permissions are properly set.

I believe there is an issue with external camera access, as I have seen this behavior when trying to develop applications to use the Camera on the A3.   

Some additional info I was able to grab from device, the following messages are continuously scrolling when running the scene when trying to use spatial mapping:

We unfortunately ran into the same problem. Spatial Meshing is not executing properly. We tried building the samples ourselves and also just running the "SnapdragonSpaces_Unity_Samples_0_11_1.apk". Both version display the following error over and over again in the LogCat, when running:

Hi,


Besides the new SDK and Samples, Spatial Mapping and Meshing also requires the latest version of the Snapdragon Spaces Services apk running on the device, and this is included with the Unity SDK download. Can you make sure this latest services apk is updated and the phone is restarted? Note that this is not the Samples apk but the *Services* apk that I'm referring to.


Thanks,

-Steve


I can confirm the latest Services APK is installed on my devices and have restarted those devices a few times.

Can you go into the Snapdragon Spaces Services apk, turn off / turn back on the Camera permissions, and do that also with your app apks?

We tried to update the Spaces Service on the device via the Spaces Service APK provided in the latest SDK download (update & also fresh reinstall) and also tried to install the service apk directly over ADB, but we still encounter the same errors as before

Hi all, 


just so I can properly investigate - when you run the samples does this panel show up for you? 



Thanks

-Simon

Regarding the logs:


2023.03.15 12:49:49.432 22268 22556 Error Unity [XR] Failed to update mesh infos

2023.03.15 12:49:49.448 22268 22556 Warn Unity [XR] Scene understanding step is not update meshes, cannot update meshes yet!


They can happen during correct behavior, but should eventually stop after a few seconds.  



@Tim If you have done a clean install of the runtime (uninstalling, then re-installing via adb, then granting permissions) and it still is not working, can you please provide a full logcat? 


Thanks again,

-Simon 

 Hey Simon,


you'll find the complete Log attached here. It starts with connecting the glasses to the device, running the Sample app, starting spatial meshing, keep it running for a few seconds and then quitting out. I hope this is helpful to you!

I forgot to mention, when running the Spatial Meshing scene I don't see the "Feature unavailable" screen. All I see Is the header "Spatial Meshing", the Snapdragon Logo and the back Button
