Question

我正在尝试解决Crashlytics针对Android应用报告的崩溃问题。根据Crashlytics的说法，崩溃只发生在Android OS 8.1上，而不是任何其他操作系统版本。

问题是来自Crashlytics的堆栈跟踪并没有给我任何关于崩溃发生位置/方式的任何线索，因为它只显示了Android SDK调用堆栈。这是堆栈跟踪：

我搜索了Stackoverflow以及其他网站关于“无法在独立视图上启动此动画制作者”，但所有这些都涉及他们自己调用的自定义类。但是，就我而言，似乎Android SDK本身崩溃了！

以前有人有类似的经历吗？堆栈跟踪是否可以说明任何内容？我应该在哪里开始研究这个问题？活动过渡？动画代码？

非常感谢任何帮助！

我知道已经晚了，但是对于其他面临此问题的人，我也有此问题。我正在使用MaterialShowcaseView，问题是当用户打开一个活动而要显示一个showCase时，如果用户立即关闭当前活动，则该活动将分离所有布局小部件。因此，显示动画无法开始，因为视图不再存在！这是open issue in github。
