广告加载错误

请选择平台： Android iOS Unity Flutter

如果广告加载失败，系统会调用一个失败回调函数，该回调函数会提供一个 LoadAdError 对象。

以下代码段会在广告加载失败时检索错误信息：

public void OnAdFailedToLoad(LoadAdError error)
{
    // Gets the domain from which the error came.
    string domain = error.GetDomain();

    // Gets the error code. See
    // https://developers.google.com/admob/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 = error.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 = error.GetMessage();

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

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

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

此信息可用于更准确地确定导致广告加载失败的原因。需要特别指出的是，对于网域 com.google.admob（在 iOS 上）和 com.google.android.gms.ads（在 Android 上）下的错误，可在这篇帮助中心文章中查询 GetMessage()，以获取更多详细说明并了解可以采取哪些措施来解决相应问题。
