Improving Android Build Performance

Explore techniques for improving Android build performance in this 46-minute Devoxx conference talk. Learn to identify performance bottlenecks using build scans, fix common issues like slow configuration time and poor parallelization, and leverage incremental annotation processing. Discover how to automate measurements, optimize JVM tuning, utilize the Gradle Daemon, and analyze build lifecycles. Gain insights on addressing red flags, extracting plugins, and implementing faster compilation strategies. Understand the benefits of incremental builds, caching, and parallelism in Gradle. Acquire practical knowledge to significantly enhance build speed and efficiency in large, complex Android projects.
