Flutter : Facebook audience network Banner error_message: No Fill, error_code: 1001 当回到之前的路由

Question

当我回到以前的路线时，我收到了 Facebook 横幅广告的这个错误:

{error_message: No Fill, error_code: 1001, invalidated: false, placement_id: **************}

Answer 1

此消息非常明显，此错误表示您实现了广告但广告未填充。您必须将您的应用上传到 Playstore，然后您的添加将自动填充。

注意:您必须从 Playstore 下载您的应用程序，然后它才会显示真正的广告。

我个人面临这个错误，只找到了这个解决方案。

您可以在测试设备中进行测试:

https://developers.facebook.com/docs/audience-network/guides/test/

facebook提到了以下原因:

Error 1001 - No Fill. May be due to one or more of the following:
User not logged into Native Facebook App on Mobile Device
Limit Ad Tracking turned on (iOS)
Opt out of interest-based ads turned on (Android)
No Ad Inventory for current user
Your testing device must have the native Facebook application installed.
Your application should attempt to make another request after 30 seconds.
