Firebase Unity SDK 4.3.0 "java.lang.AbstractMethodError"

i将Firebase Unity SDK更新为4.3.0版，并运行了Android解析器。现在，当游戏启动时，场景开始加载错误之后，它崩溃了：

注意：在我迁移到Mac并更新到Firebase Unitysdk 4.3.0

之前，它工作正常。

我能够通过以Unity删除图书馆文件夹的内容来解决此问题，并以各种订单重新刷新所有firebase软件包（我最终以4.4.1，但只是从4.4.0更新到4.4.1并未单独执行技巧）并运行Google Play架动器"强制更新"（我在更新firebase之前也尝试过，并且在清除库文件夹后，没有运气）。

我不能说这些事情最终修复了，但是如上所述，它们都没有孤立地工作，也没有对我的任何代码或资产进行任何更改。它似乎完全是一个壁炉。

有趣的是，Firebase软件包如何用不相同的文件相互覆盖，因此1）它们不是独立的，2）您导入它们至关重要的顺序。我希望他们只能创建一个多合一的资产并通过它来完成。
