Save Data on Android! Persisting data has always been a fundamental part of any app. Saving data locally or remotely with modern synchronization techniques allows your app to always be up-to-date, reactively presenting fresh data. This book is for intermediate Kotlin or Android developers who want to know how to persist data using the standard Android APIs, the Jetpack DataStore mechanism, the Room Android Architecture Component or the features Google Firebase offers. Topics Covered in This Book: Persistence with Android SDK: Learn how to manage files, SharedPreferences or SQLite databases using the APIs the Android platform offers by default. Jetpack DataStore: Learn how to persist simple data by using key-value pairs. This is Google's new and improved solution for saving data.
