Then run the following commands to create a new React Native project called "AwesomeProject":. Install the Expo client app on your iOS or Android phone and connect to the same wireless network as your computer. On Android, use the Expo app to scan the QR code from your terminal to open your project. On iOS, follow on-screen instructions to get a link. Now that you have successfully run the app, let's modify it. Open App. The application should reload automatically once you save your changes.
Expo also has docs you can reference if you have questions specific to the tool. You can also ask for help at Expo forums. These tools help you get started quickly, but before committing to building your app with Expo CLI, read about the limitations. If you have a problem with Expo, before creating a new issue, please see if there's an existing issue about it:.
If you're curious to learn more about React Native, continue on to the Tutorial. Expo CLI makes it really easy to run your React Native app on a physical device without setting up a development environment. If you want to run your app on the iOS Simulator or an Android Virtual Device, please refer to the instructions for building projects with native code to learn how to install Xcode or set up your Android development environment. Once you've set these up, you can launch your app on an Android Virtual Device by running npm run android , or on the iOS Simulator by running npm run ios macOS only.
Because you don't build any native code when using Expo to create a project, it's not possible to include custom native modules beyond the React Native APIs and components that are available in the Expo client app. If you know that you'll eventually need to include your own native code, Expo is still a good way to get started.
In that case you'll just need to " eject " eventually to create your own native builds. If you do eject, the "Building Projects with Native Code" instructions will be required to continue working on your project. Expo CLI configures your project to use the most recent React Native version that is supported by the Expo client app. The Expo client app usually gains support for a given React Native version about a week after the React Native version is released as stable.
You can check this document to find out what versions are supported. If you're integrating React Native into an existing project, you'll want to skip Expo CLI and go directly to setting up the native build environment. Select "Building Projects with Native Code" above for instructions on configuring a native build environment for React Native. Follow these instructions if you need to build native code in your project. For example, if you are integrating React Native into an existing application, or if you "ejected" from Expo or Create React Native App, you'll need this section.

While you can use any editor of your choice to develop your app, you will need to install Android Studio in order to set up the necessary tooling to build your React Native app for Android.
