广告加载错误

如果广告加载失败，系统会调用 回调 ，以提供 LoadAdError对象。

对于 an AdView，调用以下内容：

public void onAdFailedToLoad(LoadAdError adError);

fun onAdFailedToLoad(error: LoadAdError)

以下代码段说明了广告加载失败时可用的信息：

@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())
}

此信息可用于更准确地确定导致广告加载失败的原因。 尤其是对于网域 MobileAds.ERROR_DOMAIN 下的错误 ，以获取更详细的说明以及可以采取哪些措施来解决问题。

调试常见错误日志记录消息

在 Google 移动广告 SDK 23.5.0 版中，增强了详细日志记录功能，以包含广告无法加载位置的堆栈轨迹。这些消息并不表示发生了崩溃，而是会指明导致错误的唯一来源。 下表提供了常见的错误日志、说明和建议的解决操作：
