广告加载错误

当广告加载失败时，系统会调用失败回调，以提供 LoadAdError 对象。

对于任何广告格式，如果广告加载失败，系统都会调用以下回调：

public void OnAdFailedToLoad(object sender, AdFailedToLoadEventArgs args)

以下代码段会在广告加载失败时检索错误信息：

public void OnAdFailedToLoad(object sender, AdFailedToLoadEventArgs args)
{
    LoadAdError loadAdError = args.LoadAdError;

    // Gets the domain from which the error came.
    string domain = loadAdError.GetDomain();

    // Gets the error code. See
    // https://developers.google.com/android/reference/com/google/android/gms/ads/AdRequest
    // and https://developers.google.com/admob/ios/api/reference/Enums/GADErrorCode
    // for a list of possible codes.
    int code = loadAdError.GetCode();

   // Gets an error message.
   // For example "Account not approved yet". See
   // https://support.google.com/admob/answer/9905175 for explanations of
   // common errors.
   string message = loadAdError.GetMessage();

   // Gets the cause of the error, if available.
   AdError underlyingError = loadAdError.GetCause();

   // All of this information is available via the error's toString() method.
   Debug.Log("Load error string: " + loadAdError.ToString());

   // Get response information, which may include results of mediation requests.
   ResponseInfo responseInfo = loadAdError.GetResponseInfo();
   Debug.Log("Response info: " + responseInfo.ToString());
}

此信息可用于更准确地确定导致广告出现的原因 加载失败。尤其是当网域为 com.google.admob 下的错误时， iOS 和 Android 上的 com.google.android.gms.ads，GetMessage() 可 在此帮助中心内查找过 文章，详细了解 说明以及可以采取哪些措施来解决问题。
