Crash with R8 full mode enabled

[dnaka91]

Describe the bug
When enabling the full mode of R8, I directly get a crash when starting the app.

After some debugging, I found out that the problem is a reflection access through StubCreator. With full mode enabled, it modifies the ErrorReporter interface and turns it into something else (not important into what I guess, just not an interface anymore).

Expected behavior
The call should not fail.

Version

• Android: 12 (32)
• ACRA: 5.9.1

Possible solution
I got my app working again, by adding a rule to keep the ErrorReporter interface. Probably this should be added to the ProGuard rules, bundled with the acra releases.

-keep interface org.acra.ErrorReporter

I don't see any crashes in a test app, even with full mode enabled. Do you have a reproducer?

[dnaka91]

Could reproduce it very easily in a sample app:

• Created a new project with Android Studio Canary with Jetpack Compose + Material3.
• Added ACRA and called initAcra {} (without any further configuration).
• Enable R8's full mode.
