This hands-on checklist provides specific, actionable techniques for Android and iOS developers to drastically reduce cold start times. We dive deep into pre-main optimization, dynamic linker constraints, lazy initialization strategies, layout inflation bottlenecks, and advanced profiling using Systrace and Instruments. Learn exactly how to restructure your Application class, defer non-critical setup, and leverage platform-specific tools like Baseline Profiles to achieve sub-500ms startup performance. No generic advice—only concrete implementation details.
