如果广告加载失败,则一定会调用 回调 ,以此来提供LoadAdError
对象。
对于 an AdView
,系统将调用以下内容:
Java
public void onAdFailedToLoad(LoadAdError adError);
Kotlin
fun onAdFailedToLoad(error: LoadAdError)
以下代码段说明了广告加载失败时可用的信息:
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. // 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 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. // 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 via the error's toString() method. Log.d("Ads", error.toString()) }
此信息可用于更准确地确定导致广告加载失败的原因。
尤其需要注意的是,对于网域
MobileAds.ERROR_DOMAIN
( ,以了解更详细的说明和可以解决的问题对应的操作。
