@romtsn what's about -renamesourcefileattribute SourceFile? it's been removed but it was in the official docs.

Sorry I've been meaning to leave some comments here but got lost in testing the changes 😄

So I thought that we probably don't need -renamesourcefileattribute because our sdks are open-source, and there's no reason to hide the names of the files - I think this is something the consumers can decide whether they want to hide filenames from stacktraces or not and add this on themselves. This doesn't break de-obfuscation or anything, just there for security reasons (to make it harder to find out what files are causing problems)

@marandaneto should I approve it since I can't add you as a reviewer? 🤣

Also, this is what's kept at the moment (I think we did not miss anything and I gave it thorough testing, including bytecode manipulation stuff - still works, because it happens pre-R8 phase)

This crashes on release builds on AGP 7.2.1 due to the NdkIntegration using reflection.

Thanks for the report, would you mind raising a new issue with more context and stack trace? Thanks.

[romtsn]

Yeah we'd need more details - we explicitly keep SentryNdk class, so unless there's a rule which removes it, it should work fine (also, tried to reproduce - no luck)
