In this video, we will be using the firebase firestore database for performing CRUD operations inside out applications. Before that let us understand what are CRUD operations? CRUD operations are used in most applications where the data collected from users is to be stored in the database. CRUD stands for Create, Read, Update, Delete. We will be building an application where we will be displaying the list of courses and we will be able to add, update and delete the course present in the course list. We will be using Android studio as an IDE. This project will surely help beginner or intermediate-level Android developers to brush up and enhance their Android development skills.
