Hello Snapdragon Team, 

We are having issues with the Camera Frame Access Sample Scene.

For context:

We were given: 

ThinkReality A3 Leveno (HMD) 

Motorola Edge Plus (Phone)

Versions:

We have tried both the 1.0 and pre-release versions of SnapDragon Spaces, along with each version of Unity, and no configuration seemed to resolve our issue.

We made sure not to change anything with the sample before we ran the apk on our HMD the first time, and it gave us an error:

We already have the Camera Access feature enabled, so we assumed that the issue was permissions.

We then used a script that we got from another forum post that would give permission so that we could use our device's camera:

using UnityEngine;
using UnityEngine.Android;

public class CameraPermissions : MonoBehaviour
{
  internal void PermissionCallbacks_PermissionDeniedAndDontAskAgain(string permissionName)
  {
  Debug.Log($"{permissionName} PermissionDeniedAndDontAskAgain");
  }

  internal void PermissionCallbacks_PermissionGranted(string permissionName)
  {
  Debug.Log($"{permissionName} PermissionCallbacks_PermissionGranted");
  }

  internal void PermissionCallbacks_PermissionDenied(string permissionName)
  {
  Debug.Log($"{permissionName} PermissionCallbacks_PermissionDenied");
  }

  void Start()
  {
  if (Permission.HasUserAuthorizedPermission(Permission.Camera))
  {
  // The user authorized use of the camera.
  Debug.Log("Camera permission already granted.");
  }
  else
  {
  bool useCallbacks = true; // Set to true to use callbacks
  if (!useCallbacks)
  {
  // We do not have permission to use the camera.
  // Ask for permission or proceed without the functionality enabled.
  Permission.RequestUserPermission(Permission.Camera);
  }
  else
  {
  var callbacks = new PermissionCallbacks();
  callbacks.PermissionDenied += PermissionCallbacks_PermissionDenied;
  callbacks.PermissionGranted += PermissionCallbacks_PermissionGranted;
  callbacks.PermissionDeniedAndDontAskAgain += PermissionCallbacks_PermissionDeniedAndDontAskAgain;
  Permission.RequestUserPermission(Permission.Camera, callbacks);
  }
  }
  }
}

This still did not fix the issue. 

We are just confused as to why the given sample is not functioning by default. Is there anything that we are missing regarding this issue? Thanks.

Here is the screen shot that we attached to our post 

Hello Afedorch,  I hope you're doing well. I wanted to check if there are any updates on this issue. Additionally, are there any other references or resources that could help guide me in solving this problem?

Hello Andriy,

I am collaborating with Elijah on this project. We are currently using the .23 SDK version with Unity 2021.3.16f1, as we encountered issues with SDK 1.0.

If the sample functions correctly with the Lenovo ThinkReality A3, we are prepared to transition to Unity 2022.3.16f1 along with SDK 1.0.

Could you please send the sample to [email protected]?

Let me know if you need any further details or a different configuration.

Best regards,

Kyle B
