Welcome to the very start of your React Native journey! If you're looking for environment setup instructions, they've moved to their own section. Continue reading for an introduction to the documentation, Native Components, React, and more!
Many different kinds of people use React Native: from advanced iOS developers to React beginners, to people getting started programming for the first time in their career. These docs were written for all learners, no matter their experience level or background.
How to use these docs
You can start here and read through these docs linearly like a book; or you can read the specific sections you need. Already familiar with React? You can skip that section—or read it for a light refresher.
Prerequisites
To work with React Native, you will need to have an understanding of JavaScript fundamentals. If you’re new to JavaScript or need a refresher, you can dive in or brush up at Mozilla Developer Network.
While we do our best to assume no prior knowledge of React, Android, or iOS development, these are valuable topics of study for the aspiring React Native developer. Where sensible, we have linked to resources and articles that go more in depth.
Interactive examplesUse Android Apps On Mac
Jan 03, 2018 Drawables: In Android, static app images are typically added to the project’s res/drawable folder. In React Native, however, it’s recommended not to.Placing your image assets alongside your components helps to keep your components self contained, doesn’t require the app to be relaunched if you add new images. Run the command as stated below to open the boilerplate application that comes with react-native-cli. # for Mac users react-native run-ios # for Windows/Linux users react-native run-android The following screen will welcome you: A Simple WebView.

React Native enables you to build world-class native application experiences on multiple platforms using a consistent developer experience based on Javascript and React. React Native for Windows & Mac brings React Native support for the Windows 10 SDK as well as the MacOS 10.12 SDK. Jun 18, 2017 React native is now doing what is impossible few years back but now its a complete game changer technique, which would soon change the development arena and any one can developer both android and iOS apps using single language. This tutorial is for all the beginners who is thinking to learn React Native. So using this tutorial you can complete your first task to install Install React Native on MAC ( MACINTOSH ) system and create your first React Native project and run that project in real.
This introduction lets you get started immediately in your browser with interactive examples like this one:
The above is a Snack Player. It’s a handy tool created by Expo to embed and run React Native projects and share how they render in platforms like Android and iOS. The code is live and editable, so you can play directly with it in your browser. Go ahead and try changing the 'Try editing me!' text above to 'Hello, world!'
Optionally, if you want to setup a local development environment, you can follow our guide to setting up your environment on your local machine and paste the code examples into your
App.js file there. (If you are a web developer, you may already have a local environment set up for mobile browser testing!)
Function Components and Class Components
With React, you can make components using either classes or functions. Originally, class components were the only components that could have state. But since the introduction of React's Hooks API, you can add state and more to function components.
Hooks were introduced in React Native 0.58., and because Hooks are the future-facing way to write your React components, we wrote this introduction using function component examples. Where useful, we also cover class components under a toggle like so:
You can find more examples of class components in previous versions of this documentation.
![]() Developer Notes
People from many different development backgrounds are learning React Native. You may have experience with a range of technologies, from web to Android to iOS and more. We try to write for developers from all backgrounds. Sometimes we provide explanations specific to one platform or another like so:
Developer Notes
Web developers may be familiar with this concept.
Android developers may be familiar with this concept.
iOS developers may be familiar with this concept.
Formatting
Menu paths are written in bold and use carets to navigate submenus. Example: Android Studio > Preferences
Now that you know how this guide works, it's time to get to know the foundation of React Native: Native Components.

![]() Debug App in Real Android Device using USB Connection
After developing the React Native App it is always a good idea to test it on the real device because many times an app behaves differently in the emulator then the real device. This post will cover How to Run React Native App On Real Device in Windows/Linux/Mac.
Enable Debugging Over USB option
First of all, to run a debug app in your Android device you need to Enable Debugging over USB. To do this we have to do the following steps:
Go to Settings>About Phone Mac os x reinstall preview app.
Find for the Build number or MIUI version and click it multiple time, until it shows you are a developer now
You will find a Developer Option direct in settings or in Additional Settings
After that Enable Developer Option and USB debugging
Attach your Real DeviceReact Native Android App On Mac Iphone
After doing this you have to attach your Real Device with the computer using a USB cable and run the following command on terminal.
Run the AppReact Native Android Tutorial
Now run your app using App para hacer diagramas de flujo mac.
Known Issue
If you get a “bridge configuration isn’t available” error. Then use below command to solve
Here you have to replace
<device name> with your device name. You got the name using adb devices .
Now re-run the app using
Screenshot of the app running in the real deviceDeveloper Menu
If you are doing some changes and want to see in your device you have to enable the Hot/Live Reloading which can be done form the
Developer Menu . To open the Developer Menu in Real Device you just need to shack the device and it will open the Developer Menu popup for you.
This is how you can run the React Native App on Real Device. In some cases, it becomes too hectic to manage cable all the time so there is another solution to Connect Your device with the development server using Wi-Fi.
This is how you can run React Native App on Real Device. If you have anything to share please comment below or contact us here.
