Takeaways
• AndroidX is a "super user" of the Gradle build system, pushing it forward and making frequent requests and complaints.
• Configuration caching is recommended for faster build times, and most app developers will not encounter compatibility issues with major plugins.
• Local cache in Gradle allows reusing previous build results and is especially helpful when switching branches frequently or iterating on the same work.
• Remote caching in Gradle requires a server component and allows storing and retrieving build results from a remote location. Google Cloud Platform buckets can be used as a backend for remote caching in AndroidX.
• Optimization strategies for Gradle builds include continuous builds, fetching upstream dependencies from the CI cache, and handling remote dependencies.
• The speakers emphasize stability in AndroidX and Gradle, ensuring that issues are caught and fixed before impacting users.
• Collaboration with other teams is crucial for driving continuous improvement in AndroidX and Gradle, including proactive participation in testing and pushing for fixes in plugins.
• Challenges in library development include conflicts with file names, Maven Central requirements, maintaining binary compatibility, and using custom Gradle code.
• Metalava is a tool used for API review and static analysis, ensuring compatibility and preventing breakages in libraries.
• Custom lint checks and collaboration between different tools and plugins contribute to improving the user experience and overall app performance.
• The Android development ecosystem thrives on collaboration, sharing knowledge, and drawing inspiration from each other's projects and experiences.
