(MCA Semester 1 Android Using Kotlin :Unit 5) Layouts & Database Connectivity Using SQLite

Unit 5: Layouts & Database Connectivity Using SQLite

Welcome to Unit 5 of MCA2102 – Android Application Development using Kotlin, where we explore important concepts of Android Layouts and Local Database Connectivity using SQLite.

This unit provides students with a practical understanding of how Android application interfaces are structured using different layouts and how application data can be stored, retrieved, updated, and deleted locally using SQLite Database. The concepts are explained in a simple, structured, and beginner-friendly manner with practical examples using Kotlin.

You will begin by learning different Android Layout Managers, including Linear Layout, Frame Layout, Relative Layout, and Constraint Layout. These layouts help developers organize UI components and create responsive and user-friendly application screens.

The second part of this unit focuses on SQLite Database Connectivity, which allows Android applications to store structured data locally on the device. You will learn how to create and manage a SQLite database and perform essential CRUD operations — Insert, Update, Delete, and Select.

You will also learn the use of Cursor and ContentValues, which are important for inserting, retrieving, and processing database records. The unit further introduces the Database Helper Class, which provides a structured way to create, upgrade, and manage SQLite databases.

Finally, you will explore Android Data Storage APIs and understand how different storage mechanisms can be used according to the requirements of an Android application.
