New Features

Jetpack DataStore is a new and improved data storage solution aimed at replacing SharedPreferences. Built on Kotlin coroutines and Flow, DataStore provides two different implementations:

  • Proto DataStore, that lets you store typed objects (backed by protocol buffers)
  • Preferences DataStore, that stores key-value pairs

Data is stored asynchronously, consistently, and transactionally, overcoming most of the drawbacks of SharedPreferences.
