This information will guidebook you thru the process phase-by-move, covering both equally exporting and importing functionalities utilizing functional illustrations and Kotlin code snippets.

Knowing the basic principles
SQLite Database in Android
SQLite is a lightweight databases that comes bundled with Android and is also well suited for storing structured information.
