Modern Android Persistence Options
A practical overview of DataStore, Room, and JSON serialization for Android apps.
Modern Android Persistence Options
Android apps usually need more than one persistence tool. Use DataStore for small preference-style values, Room for structured local data, and JSON serialization when you need a portable representation.
When should you use DataStore?
DataStore is a strong default for small settings and state that previously lived in SharedPreferences.
When should you use Room?
Room fits structured local data, especially when records need queries, relationships, and migrations.
