If you’re using iOS, run the command below to install the necessary React Native packages: cd ios & pod install & cd. To install SQLite, run the following code in your terminal: npm install -save react-native-sqlite-storage Install React Native packages iOS To connect with SQLite, we are going to use the react-native-sqlite-storagelibrary. Let’s introduce SQLite to our application. You’ll see there are two branches in the repository, start and main. You can clone the React application and work along as you read through the article. ![]() We’ll start by creating a React Native app using TypeScript: npx react-native init MyApp -template react-native-template-typescript Note that we’ll use a set of functional components and several new hook APIs to achieve state management. Dumb component: shows a to-do list item.App component: handles user events like adding and deleting to-do list items.Two useState calls: one for keeping a to-do list and one for tracking new to-do items.We’ll create a to-do list application that includes the following: Basic understanding of React and React Native.We’ll also use TypeScript on account of its advantages like code quality and maintainability. In this article, we’ll use SQLite in a React Native application to set up a simple to-do list application that will show us how all the CRUD operations are working. SQLite is especially useful for offline applications, and many platforms include support for SQLite out of the box, making it straightforward to install. To learn more about SQLite, visit the official website.It’s very common for developers to use SQLite, a C-language library, as the datastore in mobile applications. SQLite has built-in support for transactions, views, subqueries, and triggers. It is ideal for small to medium-sized applications and provides all the essential features of a database engine without the overhead of a full-scale relational database management system (RDBMS). SQLite is an embedded database, meaning it is stored directly in the application that uses it. SQLite is a lightweight, serverless, self-contained SQL database engine that allows developers to create and manage databases without the need for a separate server or complex setup. This class also encapsulates the logic for Create, Read, Update, and Delete (CRUD) operations. It aids managing the creation and versioning of your SQLite database. DatabaseHelper ClassĪ 'DatabaseHelper' class in Android development extends the SQLiteOpenHelper class. Learn more about CRUD operations at Wikipedia. Performing CRUD operations efficiently is crucial for maintaining the performance, consistency, and integrity of your application's data. These operations are essential for any application that involves data storage and retrieval. If you need assistance with your Android app development or are looking to hire Android developers, visit Reintech for more information.ĬRUD (Create, Read, Update, and Delete) operations are the fundamental functions required for managing and manipulating data in a database. This should serve as a solid foundation for further development. We created a helper class for managing database creation, versioning, and CRUD operations, and integrated it into our main activity. ![]() In this tutorial, we have learned how to develop a database-driven Android app using SQLite. For example, insert a new record:ĭatabaseHelper dbHelper = new DatabaseHelper(this) In your main activity, create an instance of the "DatabaseHelper" class and use it to perform CRUD operations. Step 4: Integrating the Database Helper Class in the Activity Public class DatabaseHelper extends SQLiteOpenHelper ) This class will help manage the database creation, version management, and CRUD operations. ![]() Step 2: Creating the Database Helper ClassĬreate a new class called "DatabaseHelper" that extends the SQLiteOpenHelper class. Implementation 'nstraintlayout:constraintlayout:2.0.4'ĪndroidTestImplementation ':junit:1.1.2'ĪndroidTestImplementation ':espresso-core:3.3.0'Ĭlick "Sync Now" to update your project with the added dependencies. Implementation 'androidx.appcompat:appcompat:1.2.0' Once your project is set up, open the adle file (Module: app) and add the following dependencies: Give your project a name and set the package name, then click "Finish". Choose the "Empty Activity" template and click "Next". Step 1: Setting Up the Android Studio Projectįirst, create a new Android Studio project by selecting File > New > New Project. ![]() This tutorial assumes you have a basic understanding of Android app development and Java programming. SQLite is a lightweight and serverless database engine that allows you to create local databases for your Android applications. In this tutorial, we will learn how to develop a database-driven Android app using SQLite.
