using Vuforia;

VuforiaRenderer.Instance.Pause(true);

In our sample app, the CameraSettings.cs script has the following function that properly stops and restarts Vuforia:

private bool RestartCamera(CameraDevice.CameraDirection direction)
    {
        ObjectTracker tracker = TrackerManager.Instance.GetTracker<ObjectTracker>();
        if (tracker != null)
            tracker.Stop();

        CameraDevice.Instance.Stop();
        CameraDevice.Instance.Deinit();

        if (!CameraDevice.Instance.Init(direction))
        {
            Debug.Log("Failed to init camera for direction: " + direction.ToString());
            return false;
        }
        if (!CameraDevice.Instance.Start())
        {
            Debug.Log("Failed to start camera for direction: " + direction.ToString());
            return false;
        }

        if (tracker != null)
        {
            if (!tracker.Start())
            {
                Debug.Log("Failed to restart the Tracker.");
                return false;
            }
        }
           
        return true;
    }

Could you try something similar to what is being done in this function and let me know if that resolves your issue.

Thanks and sorry for the delayed response,

hi,

Please find the attached script which I am using to pause and resume the camera.

when application restarted means background to foreground the image(texture) has been lost. I want the same image on the camera screen.

Thanks

Hello satampratham,

What code are you using to pause the ARCamera? Are you doing this to because you need to run some code that requires Vuforia to not be running?

Thanks,
