It uses key-value pairs to store simple data.With all that, you have to access Sharedpreferences to read the whole file no matter how large it is, bring the data in memory while all this is happening on the UI thread. This is because when using the app, you try to access the value of a particular key as soon as the app launches. The most common reason is the long-running tasks on the main UI-thread. If you have worked with Sharedpreferences you might have gotten an ANR (Application Not Responding) on your app. It has a few drawbacks that make it a little bit complex to work with.

How to implement datastore preferences.Key differences between datastore and SharedPreferences.Good understanding of Kotlin (as we will use it as our primary language).This way you will not have to worry about referential integrity or partial updates. If you are working with large/complex datasets, consider using Room. It works well with small simple datasets. Introductionĭatastore uses Kotlin coroutines and flow to store data asynchronously, consistently, transactionally, and to handle data corruption. We will work on how to change the UI mode of an app. In this tutorial, we will learn how Jetpack DataStore works. DataStore is an improved data storage solution by Google to replace SharedPreferences for persisting simple pieces of data such as key-value pairs or typed objects with protocol buffers.
