Delete data from SQLite database

In this tutorial, we’ll explore the process of deleting data from an SQLite database, building on our previous lesson where we covered updating data in the database. Specifically, we’ll focus on enhancing our Phone Book app by adding functionality to delete contact numbers. In our prior tutorial, we implemented a popup triggered by clicking a list item, offering two choices: update and delete. In this tutorial, we’ll guide you through the steps to delete a contact when the user selects the delete option. Let’s dive into the process of efficiently managing and modifying your SQLite database. To initiate the deletion of data, our first step involves introducing a new method named deleteData() within the DatabaseHelper class. This method serves as a crucial component in our process of removing specific records from the database. Take a look at the following code snippet to integrate this functionality into your application. DatabaseHelper Class Code: Following the implementation of the deleteData() method in our DatabaseHelper class, the subsequent action involves invoking this method in our main class when the user opts for the delete option within the popup. Please check out the provided code snippet to integrate this functionality into your main class.
