Worked on the firebase/firebase-android-sdk repository, focusing on enhancing stability and compatibility for Crashlytics in Gradle-based Android projects. Addressed a specific incompatibility between the Crashlytics Gradle plugin and Gradle’s isolated project mode, particularly improving the GenerateSymbolFileTask to function reliably in multi-module setups. The solution involved targeted Kotlin development and adjustments to Gradle build tool configurations, ensuring robust symbol generation across isolated project environments. By resolving issues #8038 and #8037, the work reduced fragile behavior in symbol handling and improved cross-project integration. The engineering approach emphasized precise bug fixing and careful tracing of changes within complex build toolchains.
