部署到移动设备时不会加载来自 amazon s3 的资产

Question

这是我第一次尝试使用amazon s3，我还在学习中。我正在尝试从 Amazon s3 为一个简单的 AR 应用程序加载资产包。当相机正在查看特定图像时，我正在使用 Vuforia 加载蜘蛛。该资产在未从亚马逊加载时工作得很好，但现在在构建到我的 phone 时从未加载该资产，但它确实会统一加载。我已经设置了权限，所以每个人都可以从资产包中读取。

我不确定 android SDK 中是否有我需要做的事情。

这是我用于从 amazon s3 加载资产的脚本：

public Text debugText;
// initialization
void Start()
{
    string url = "This is a url";
    WWW www = new WWW(url);
    StartCoroutine(WaitForReq(www));


}

IEnumerator WaitForReq(WWW www)
{
    yield return www;
    AssetBundle bundle = www.assetBundle;
    if (www.error == null)
    {
        GameObject SPIDER = (GameObject)bundle.LoadAsset("SPIDER");


        //For debugging, see if asset is being loaded
        debugText.text = ("Object has loaded");


        //Instantiates at the location of where the ImageTarget is
        var loadedAsset = Instantiate(SPIDER, new Vector3(transform.position.x, transform.position.y, transform.position.z), Quaternion.identity); 
        //Makes transform of loadedAsset the transform of the ImageTarget 
        loadedAsset.transform.parent = gameObject.transform;
        loadedAsset.gameObject.active = false;
    }
    else
    {
        Debug.Log(www.error);
    }
}

好的，谢谢 dome12b。感谢您发布如何让 android 调试器运行，我能够自己解决它。原来在我开始这个项目的时候，我统一创建了资产包到错误的构建目标。我所要做的就是将资产包的构建目标更改为 android 并且很快，它现在可以工作了！。再次感谢您为我指明了正确的方向。
