我尝试了广告单元测试及其工作，但我的单元没有

Answer 1

在我 posted 组 Google 移动广告 SDK 技术论坛 之后，他们回复了

"I suggest to load test ads instead of live ads to avoid invalid activities. You may do this with your live Ad Unit ID and enabling test device. The error code 3 that you encountered means that an ad request is successful but it can't return ads due to lack of ad inventory. Also, please note that that loading your Ad Unit IDs on an unpublished app may have an impact fill rate."

在我发布应用后，广告成功展示
