android - Admob Native 广告加载失败，错误代码为 0

Question

我遇到了某种问题。

我尝试使用

手动

https://developers.google.com/admob/android/native

快速入门

https://developers.google.com/admob/android/quick-start .

对于由 AdView 加载的简单横幅来说还可以，但是当我改为通过 AdLoader 加载原生广告时，我真的卡住了。

我正在使用 Idea + Gradle 和 Android Annotations。

这是 Logcat(已更新，请查看问题的结尾):

我错过了什么吗？

或者 Admob 仍然不支持原生广告？

我还尝试了将我的应用程序单元 ID 从测试更改为真实单元、在模拟器/设备上进行测试以及清除设备上 Google Play 服务的缓存数据等操作 - 结果相同。

任何帮助/想法将不胜感激......

更新:我已经从 gradle 的配置中删除了 multidex 模式，并将 buildToolsVersion 更改为最新版本 (22.0.1)，logcat 已更新到问题的顶部。现在方法 fetchAd 的第一次调用失败，代码为 2(超时)，接下来的调用如前所述失败，代码为 0。请查看更新后的 Logcat

更新2:真实设备的日志(android api 级别 15):

注释来自 documentation

Note: At the current time, publishers should not use the addTestDevice method with native ad requests. Using the above ad unit ID with calls to addTestDevice is the current best practice for testing.
