Worked on the microsoft/vscode-react-native repository to enhance Android package name resolution, focusing on aligning the process with modern Android project structures. Developed a feature that prioritizes the applicationId specified in build.gradle over the package name in AndroidManifest.xml, addressing common issues in multi-module setups. Implemented a new parser for extracting applicationId from Gradle files and updated the resolution logic to ensure reliable launching and debugging. Expanded unit testing to cover various Gradle-based configurations, improving test coverage and reliability. Documented the updated behavior for developers and maintainers. Utilized TypeScript and Android development skills with a strong emphasis on unit testing.
