有谁知道如何集成 Millennial Media 原生广告适配器？
我读了这个页面： https: //support.millennialmedia.com/hc/en-us/articles/205081010-MoPub-Integrations
下载了 android 适配器，然后用我的 APID 替换 APID，但不知道 DCN 是什么，我无法在他们的网站上找到它。
我想我收到以下错误是因为我没有输入 DCN：
03-24 22:07:12.832 29491-29491/? D/MoPub：尝试调用自定义事件：com.mopub.nativeads.MillennialNative 03-24 22:07:12.850 29491-29491/? V/MoPub：原生广告加载失败，出现错误：CustomEventNative 配置不正确.. 03-24 22:07:13.328 29491-29491/? D/MoPub：尝试调用自定义事件：com.mopub.nativeads.MoPubCustomEventNative
这是我正在使用千禧年媒体的他们的适配器：
