Beike Cold Start Optimization
This article details the optimization of cold startup times in Android applications using ASM and method tracing techniques to improve performance and user experience.
本文介绍了在Android应用中优化冷启动时间的方法，采用ASM插桩和方法追踪技术，旨在提升应用性能和用户体验。主要内容包括：
1. 方法调用信息收集：通过ASM框架在方法前后插入记录代码，收集方法调用顺序和耗时信息。
2. 模拟方法调用栈：根据收集的顺序反向还原调用链路，关联方法开始和结束。
3. 自定义方法统计工具：结合ASM插桩和模拟栈，实现高效准确的方法耗时统计。
4. 方法调用拦截器：支持过滤特定方法，仅收集关键路径的耗时信息。
5. 可视化展示：提供线程耗时统计、方法耗时统计和调用栈展示页面，帮助开发者快速定位性能瓶颈。
