我将Firebase Unity SDK更新到版本4.3.0并运行了Android解析器。现在，当游戏启动时，它会在场景开始加载后崩溃：

注意：在我迁移到Mac并更新到Firebase UnitySDK 4.3.0 之前，它工作正常
答案 0 :(得分：0)
我能够通过删除Unity中的Library文件夹的内容来解决这个问题，以不同的顺序多次重新导入所有Firebase软件包（最后是4.4.1，但只是从4.4.0更新到4.4。 1并没有自己动手）并运行GooglePlay Resolver＆＃34;强制更新＆＃34; （我在更新Firebase之前尝试了这一点，并在清除了Library文件夹之后，没有运气）。
我不能说这些事情中的哪一个最终修复了它，但如上所述，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Firebase的一部分。
有趣的是Firebase软件包如何使用不相同的文件覆盖彼此，所以很明显1）它们不是独立的，2）导入它们的顺序很重要。我希望他们能够创建一个单一的一体化资产并完成它。
