Storing data locally is a key part of many Android apps. SQLite is built into Android, but the low-level API that the Android SDK provides is a bit clunky to use.
Google’s solution for that is Room, an object wrapper around that API. This gives us a cleaner, type-safe, reactive API for our database operations. Room is part of the Android Jetpack, and so it is a key element of Google’s recommended “stack” of technologies for building Android apps.
This book explores Room, starting with basic stuff like:
- Adding Room to your app
- Defining your entities and data access operation (DAO) APIs
- Testing your database I/O
- Using Room with Kotlin coroutines, LiveData, and RxJava
- Migrating your database schema as your app evolves
It also gets into more elaborate scenarios, such as using SQLCipher for Android for encrypting your Room database.
