问题
Google has recently updated the Google Play Console, and now crashes are automatically reported.
Since almost all stack traces I got are not accurate anymore:
- The stack trace is full of
<OR>methods, so I guess full of possible candidates? - All the line numbers are
0
Note that I use Proguard (and not Multidex) and I strongly suspect it is the cause of the problem.
Example:
java.lang.ClassCastException:

I fixed this bug and the issue was in the getItemViewType method and not in the first displayed one (getItemCount). So these stack traces are really useless compared to previous ones. You know there is a bug but you don't know exactly where it occurs.
Do you experience the same issues? Does someone know how to fix it?
回答1:
I think this is because proguard retrace cannot unambiguously identify the stack frame when line numbers are omitted (see https://www.guardsquare.com/en/proguard/manual/retrace#without).
From these docs, it looks like it's necessary to preserve the LineNumberTable in order to remove ambiguity.
