错误处理
如果广告加载或展示失败，您的广告展示委托或回传接口会收到调用。 该调用带有一个错误代码。 本页介绍了这些错误代码。
错误对象
您在回传中收到的错误是一个实现 MAError 的一等 (first-class) 错误对象。
该对象具有以下 API：
code- 错误代码，见下表。
message- 描述该错误的可读信息。
mediatedNetworkErrorCode- 被聚合平台针对该错误的错误码。 仅适用于广告展示失败回传中返回的错误。
mediatedNetworkErrorMessage- 返回被聚合平台针对该错误的错误信息。 默认为空字符串。 仅适用于广告展示失败回传中返回的错误。
getWaterfall()- Allows you to see the information about the current waterfall for an ad that loads or fails to load. The network responses provide the ad load state, latency, credentials, and mediated network information for each ad in the waterfall. If an ad in the waterfall fails to load, the network response provides error information. You can learn more about this method in Advanced Settings: Waterfall Information API.
