Understanding Android ART CC Collector: GC Challenges, Implementation Principles and Performance Optimization
The article thoroughly explains Android ART’s Concurrent Copying (CC) garbage collector—its terminology, correctness and progress requirements, engineering challenges, classic and Android‑specific algorithms, region‑based design with bump‑pointer allocation, performance benefits such as 32% lower heap usage and sub‑millisecond pauses, and its trade‑offs including doubled reserved heap space and migration overhead.
