Android IllegalStateException无法在分离视图上启动此动画师

我正在尝试对Crashlytics报告的Android应用程序崩溃进行故障排除。据Crashlytics称，崩溃只发生在Android OS 8.1上，而不会发生在任何其他OS版本上

问题是Crashlytics的堆栈跟踪根本没有给我任何关于崩溃发生在哪里/如何发生的线索，因为它只显示了Android SDK调用堆栈。以下是堆栈跟踪：

我搜索了Stackoverflow以及其他关于“无法在分离视图上启动此动画师”的网站，但所有这些都涉及调用它们自己的自定义类。然而，在我的情况下，似乎Android SDK本身崩溃了

以前有人有过类似的经历吗？堆栈跟踪有什么意义吗？我应该从哪里着手调查这个问题？活动转换？动画代码

非常感谢您的帮助

我知道为时已晚，但对于其他面临这个问题的人来说，我也有这个问题。

我正在使用，问题是当用户打开一个活动，并且希望出现一个

showCase

时，如果用户立即关闭当前活动，该活动将分离所有布局小部件。因此，显示动画无法启动，因为视图已不存在！这是一个。

我希望这能帮助您：您是否正在使用

材质ShowCaseView

？
