无法弄清楚 Google Play 控制台堆栈跟踪峰值

Question

最近，我的 Google Play 管理中心崩溃率开始大幅上升。我无法弄清楚到底发生了什么。这是去混淆的堆栈跟踪，但它并没有真正告诉我发生了什么。我无法复制这个问题，但我每天会收到数百个。它似乎可能与一个班级联系在一起，但给了我一行 0，这显然没有帮助。在所有这些语句中，我以前从未见过像这样的堆栈跟踪。有人知道是什么原因造成的吗？

编辑：见New Google developer console crashes stack traces are not accurate anymore，这是因为当缺少行号时，proguard 去混淆是不明确的。
