Bundle vs HashMap in Android: Memory Efficiency and Performance
In Android, Bundles backed by memory‑efficient ArrayMap use binary search and shrinkable storage, making them far smaller and faster to transmit than HashMaps, whose fixed‑size growth and lack of shrinkage consume more memory; thus Parcelable Bundles are preferred for IPC, while Serializable remains suited only for persistent storage.
