The New Modern Data Persistence on Android - Meet Jetpack Datastore

on YouTube ↗25m

" summary

Demonstrates Jetpack DataStore with concrete code: uses Preferences DataStore for simple key-value pairs (taskTitle, taskDescription, taskPriority:int, taskCompleted:bool) with createDataStore, edit, data.map and flow.collect; shows Proto DataStore using a src/main/proto task message, generated serializer and updateData, and notes requiring protobuf Java Lite 3.18.1 and an M1 workaround. Compares performance, type safety, versioning and schema evolution versus SharedPreferences; uses Budgeting Buddy as a dogfood app and keeps Room for complex relational data.
