This paper discusses unpacking APKs (which are ZIP files) before applying delta encoding. It highlights that applying delta algorithms directly to compressed APKs is inefficient, whereas unpacking them first can reduce update sizes by up to 77%. Detailed on ResearchGate 4. Technical Standard (RFC) is a native C implementation of the
