廣告載入錯誤

如果廣告無法載入，系統會呼叫 回呼 ，提供 LoadAdError物件。

針對 an AdView，會呼叫以下內容：

public void onAdFailedToLoad(LoadAdError adError);

fun onAdFailedToLoad(error: LoadAdError)

以下程式碼片段說明廣告載入失敗時可用的資訊：

@Override
public void onAdFailedToLoad(LoadAdError error) {
  // Gets the domain from which the error came.
  String errorDomain = error.getDomain();
  // Gets the error code. See
  // https://developers.google.com/android/reference/com/google/android/gms/ads/AdRequest#constant-summary
  // for a list of possible codes.
  int errorCode = 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 errorMessage = error.getMessage();
  // Gets additional response information about the request. See
  // https://developers.google.com/admob/android/response-info for more
  // information.
  ResponseInfo responseInfo = error.getResponseInfo();
  // Gets the cause of the error, if available.
  AdError cause = error.getCause();
  // All of this information is available using the error's toString() method.
  Log.d("Ads", error.toString());
}

override fun onAdFailedToLoad(error: LoadAdError) {
  // Gets the domain from which the error came.
  val errorDomain = error.domain
  // Gets the error code. See
  // https://developers.google.com/android/reference/com/google/android/gms/ads/AdRequest#constant-summary
  // for a list of possible codes.
  val errorCode = error.code
  // Gets an error message.
  // For example "Account not approved yet". See
  // https://support.google.com/admob/answer/9905175 for explanations of
  // common errors.
  val errorMessage = error.message
  // Gets additional response information about the request. See
  // https://developers.google.com/admob/android/response-info for more
  // information.
  val responseInfo = error.responseInfo
  // Gets the cause of the error, if available.
  val cause = error.cause
  // All of this information is available using the error's toString() method.
  Log.d("Ads", error.toString())
}

您可以利用這項資訊，更準確地判斷廣告載入失敗的原因。 特別是針對 MobileAds.ERROR_DOMAIN 網域下的錯誤，訊息 可在這篇說明中心文章中查詢，瞭解更詳細的說明，以及可採取的解決問題行動。
