廣告載入失敗時,一律會呼叫 回呼 ,藉此提供LoadAdError
物件。
對 an AdManagerAdView
來說,系統會呼叫下列程式碼:
Java
public void onAdFailedToLoad(LoadAdError adError);
Kotlin
fun onAdFailedToLoad(error: LoadAdError)
下列程式碼片段說明廣告無法載入時可用的資訊:
Java
@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. 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 via the error's toString() method. Log.d("Ads", error.toString()); }
Kotlin
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. 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 via the error's toString() method. Log.d("Ads", error.toString()) }
這項資訊可用來更準確地判斷出廣告載入失敗的原因。
