android admob拒绝对先前失败的类java.lang.Class <uo>进行重新初始化：java.lang.NoClassDefFoundError eror

时间：2018-12-03 06:02:37

标签： android admob

任何时候都没有admob广告出现时，我会收到此错误消息。

解决方法是什么？

在我的记忆中，该广告最初正常显示，但从没出现过。

受测设备的Android版本为8.0.0、8.1.0。

MainActivity.java:432 => MobileAds.initialize("~");

我同时检查了App ID和Unit ID。
