How To Build An App With React Native

Today is the 21st century.  Our world becomes more modern and every day develops different technologies. IT is a popular theme today. We use mobile or web applications every day. There are various kinds of apps. For example, gaming apps, business and educational, lifestyle, entertainment, and travel apps. I think every person wants to create their app. In this case, you have had a question in your head: “How to create an application?”. I tell you how to create an app with React Native.  Oh! You probably don’t know what React Native is. It’s not a problem! I explain to you in a nutshell.

React Native

React Native is an open-source cross-platform application development framework. It was developed by Facebook. You can build Android and iOS apps using the framework. The React Native framework with its mobile app developers is widely used by some of the top online brands such as Skype, Walmart, Airbnb, Adidas Glitch, Tesla, Facebook, Instagram, and more.

React Native allows you to create unique, engaging user interfaces using pre-built declarative components like Picker, Button, Slider, Switch, etc. There are many iOS and Android components that make it work efficiently on Android and iOS mobile devices. React Native provides components for text, images, keyboard input, scrollable lists, progress bars, animation, clipboard, links, and more. These components greatly speed up the app development process. The function “Hot Reloading” also saves a lot of time as it allows you to reload the application without recompiling all the code.

How to build an Android app with React Native

First of all, you need to write your code in JavaScript. The ReactJS code allows excellent UI and user experience components. In the second place, you download and install React Native. The first way to install React Native is to use expo-cli. Expo is a collection of tools, libraries, and services that allow you to create your own app. Expo helps you view projects while you are still developing them. The Expo CLI generates a development URL, which you can then open in the Expo CLI to preview your application. The Expo-CLI download and install the React Native, which is integrated with the Expo API. It is one of the simplest ways to build your app, especially when you just began to work with React Native. You can run and test the app without configuration. You can just scan the QR code and your newly created app will open with the expo mobile app. The other way to install React Native is to use React Native CLI. I want to say that React Native CLI works in the same way as Expo CLI. The difference is that Expo CLI has another method and additional benefits. In case, when you install applications with React Native you can create your native modules in your app. To begin with, that when you want to create an Android app you should download and configure both Android SDK and Android Studio

Android SDK

Android SDK is a software development kit that helps developers create applications for the Android system. Android SDK supports a large number of devices. For example,  mobile phones,  tablet computers,  smart glasses ( including  Google Glass), modern cars with on-board computers on the Android OS, TVs with advanced functionality, special types of wristwatches, and many other gadgets and overall technical devices.

Android Studio 

Android Studio is an application development environment for the Android mobile platform. It is a universal development environment because it allows users to optimize the work of future applications to work not only on smartphones but also on tablets, portable PCs that run based on the operating system in question. If you have downloaded Android Studio, you need to install some APIs. You need to open Android Studio and to press on “system settings”. In the first place, I recommend you to check the platform. You can choose any of the platforms you want to support your React Native. Then you need to shift to SDK tools. The next step is to verify SDK-Build-Tools and Android SDK tools and google play service. In the Android Build-Tools selection, select all the platforms. After that, you need to create an emulator (or the simulator). What is it? The emulator is playbacking, by software or hardware or a combination of other programs or devices. You can test the application with the help of an emulator. In this case, you can use Android Studio emulators or a real device instead. There are also a lot of different emulators, for instance, XePlayer, WinDroy, Genymotion, Memu, LDPplayer, AMIDuOS. I tell you shortly about AMIDuOS.

AMIDuOS

AMIDuOS is an Android emulator with a minimal feature set. The program will allow you to run applications for the popular mobile platform on your PC, work with the Android operating system itself, and create screenshots.

How to build an IOS app with React Native

In the same way as the Android app, you can create an IOS app. React Native can run in Android and IOS. However, React Native has some exceptions when it runs on IOS. For instance, you should have a Mac OS. One of the differences and one of the advantages in contrast to Android is that you don’t need to download the SDK to run React Native on IOS. Firstly, you configure authentication for your React Native IOS application. Therefore you run your app on the IOS simulator. The most popular IOS simulators are Ripple, TestFlight, Electric Mobile Studio, iPadian. And then you adjust styling.

React Native libraries such as Redux (for handling the state of your app) and Awesome React Native (list of components and demos) will also help you finish your mobile app development faster.

Conclusion

To sum up, I want to say that building a mobile application with React Native is not as difficult as you might think. Hiring a React Native Development Company might be the best choice for you because they can easily build mobile applications that can run on IOS and Android. You can also create both native and cross-platform mobile apps.

Thank you for taking the time to read the article! I wish you to be careful and take care of your health.
