Build System

AGP Version

NA

Proguard

Enabled

Version

6.23.0

Steps to Reproduce

1. Create a simple Android app
2. Run the following code in debug mode to trigger a ArrayIndexOutOfBoundsException
   
3. Note the line number in Sentry is correct (525)
4. Run the same code again but now in release mode

Expected Result

The line number in the crash report from release mode is the same is in the debug mode. This is the screenshot from the debug mode:

Actual Result

The line number in the crash report is incorrect (line 3)

Proguard mapping is uploaded to the project and applied to the affected event:
Event:

"uuid": "123e8712-e89b-12d3-a456-426614174910",
"type": "proguard"

The result using retrace also shows line 3 as the affected line:

@rodolfoBee if retrace yields the same result I doubt we can do much more about it from our side. This is how lambdas are optimized by r8, and if they themselves cannot recover the original stacktrace I'm not sure we can.
