Vuforia init error #151

Open davidGM-00 opened 4 years ago

davidGM-00 commented 4 years ago

Hi, I'm working in a flutter + Unity + Vuforia app and when I install the app in my device the unity scene works, but if I come back with the android button the app crash and when I open the app again and I can't start the unity scene because Vuforia can't init, "Vuforia Engine Initialization Error", "Init Error"

Hi there, I had the same error, I could fix it by setting Delayed Initialization in Vuforia setting

and add a script to the camera to initialize it after some delay (for me it works when I put 3 seconds delay)

using System.Collections; using System.Collections.Generic; using UnityEngine; using Vuforia;

public class VuforiaInit : MonoBehaviour { public Camera ARCamera; int index = 0; private float timeLeft = 0.0f;

void Update()
{
    timeLeft+=Time.deltaTime;
    if (timeLeft>=3.0)
    {
        VuforiaRuntime.Instance.InitVuforia();
        ARCamera.GetComponent<VuforiaBehaviour>().enabled = true;
        print(timeLeft.ToString());
    }
}

}
