Summary
The bundled proguard.txt consumer rules in rollbar-android contain a global ProGuard/R8 option (-renamesourcefileattribute) that should not be specified in library consumer rules. Android's build tooling flags this as a violation and reports it to developers via lint.
Steps to Reproduce
- Add
rollbar-android as a dependency in any Android project - Run Android Studio's built-in code analyzer (or build with lint enabled)
- Observe the following warning:
The consumer keep rules at rollbar-android-2.2.0/proguard.txt contains a global option which should not be specified in library consumer rules:
-renamesourcefileattribute rollbar
Root Cause
rollbar-android's proguard.txt contains:
-renamesourcefileattribute rollbar
-renamesourcefileattribute is a global ProGuard/R8 option. When placed in a library's consumer rules it is applied to the entire app, not just the library's own classes. This means:
- It overrides the app developer's own
-renamesourcefileattribute setting - If multiple libraries include conflicting global options, behaviour is unpredictable
- Android's build tools explicitly flag global options in consumer rules as incorrect practice
Expected Behaviour
Library consumer rules should only contain -keep, -keepclassmembers, -dontwarn, and similar scoped rules. Global options like -renamesourcefileattribute must not be in consumer rules.
Suggested Fix
Remove -renamesourcefileattribute rollbar from proguard.txt and instead document it in the integration guide as something the app developer should add manually to their own
proguard-rules.pro if they want Rollbar's source mapping behaviour:
# Add to your app's proguard-rules.pro if using Rollbar source mapping
-renamesourcefileattribute SourceFile Environment - rollbar-android version: 2.2.0
- Android Gradle Plugin: 9.1.1
- R8 / ProGuard
