👉 Overview
👀 What ?
React Native is a JavaScript framework for writing real, natively rendering mobile applications for both iOS and Android. It is based on React, Facebook’s JavaScript library for building user interfaces, but instead of targeting the browser, it targets mobile platforms.
🧐 Why ?
Android React Native Application development is important because it allows developers to write applications for Android using JavaScript, a language many web developers are already familiar with. This means that web developers can transition to mobile development more easily. Additionally, because React Native allows for code reuse across platforms, it significantly shortens development time.
⛏️ How ?
To create an Android React Native application, you first need to set up your development environment. This includes installing Node.js, the React Native command line interface, a Java Development Kit, and Android Studio. Once your environment is set up, you can create a new React Native project by running 'npx react-native init ProjectName'. After creating the project, you can run your React Native application on Android by running 'npx react-native run-android'.
⏳ When ?
React Native was first released by Facebook in 2015. Since then, it has grown in popularity and is now used by many large companies like Facebook, Instagram, Airbnb, and more.
⚙️ Technical Explanations
React Native works by using JavaScript to control native components in Android via a JS-native bridge. When a React Native app is built, the JavaScript code is bundled into a file that's executed by JavaScriptCore, a JavaScript engine. This JavaScript code controls the user interface and responds to user actions by sending messages across a bridge that links JavaScriptCore and the native side of the app. On the other side of the bridge, native code translates these messages into commands that control the user interface.
