android - 新的 Google 开发者控制台崩溃堆栈跟踪不再准确

Question

Google 最近更新了 Google Play 管理中心，现在会自动报告崩溃情况。

因为我得到的几乎所有堆栈跟踪都不再准确:

• 堆栈跟踪充满 <OR>方法，所以我猜充满了可能的候选人？
• 所有行号均为0

请注意，我使用 Proguard(而不是 Multidex)，并且我强烈怀疑这是问题的原因。

我修复了这个错误，问题出现在 getItemViewType 中方法而不是第一个显示的方法( getItemCount )。所以这些堆栈跟踪与之前的堆栈跟踪相比确实毫无用处。您知道存在错误，但不知道它到底发生在哪里。

您是否也遇到过同样的问题？ 有人知道如何解决吗？

Answer 1

我认为这是因为当省略行号时，proguard retrace 无法明确识别堆栈帧(请参阅 https://www.guardsquare.com/en/proguard/manual/retrace#without )。

从这些文档来看，似乎有必要保留 LineNumberTable 以消除歧义。
