Serial: Improving Data Serialization on Android
summary
Twitter for Android replaces Java Serializable with a custom framework called serial that uses explicit object serializers and static instances to write compact typed streams, adds version headers and a builder serializer to keep old rows readable, and prints structured stream dumps for clearer errors. One measured model (tweet entities) drops round‑trip from ~9ms to <3ms and stream size from ~2300 to ~500 bytes (≈3× faster, ≈5× smaller). Library is open source and used across the app.
