summary

Jetpack DataStore replaces heavy SharedPreferences use by offering Preferences DataStore for key‑value pairs and Proto DataStore for strongly typed protobuf objects, runs on Dispatchers.IO with coroutines and Flow, and ships a SharedPreferencesMigration that automatically migrates old files. Demo shows a launch counter app and a protobuf-backed filter settings store using the protobuf Gradle plugin and generated serializer; current artifact is alpha05, no built‑in encryption but serializers support custom encryption.
