You've successfully run and modified your first React Native app. The application should reload automatically once you save your changes. Open App.js in your text editor of choice and edit some lines. Modifying your appNow that you have successfully run the app, let's modify it. On iOS, use the built-in QR code scanner of the Camera app. On Android, use the Expo app to scan the QR code from your terminal to open your project.Running your app on a simulator or virtual deviceExpo CLI allows you to run your React Native app on a physical device without setting up a development environment. in the Expo issues (for issues about the Expo client or SDK).If you're curious to learn more about React Native, check out the Introduction to React Native. in the Expo CLI issues (for issues related to Expo CLI), or 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:
Select "React Native CLI Quickstart" above for instructions on configuring a native build environment for React Native.Brew install -cask adoptopenjdk/openjdk/adoptopenjdk8 CopyIf you have already installed JDK on your system, make sure it is JDK 8 or newer. 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. 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. If you do eject, the "React Native CLI Quickstart" 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. In that case you'll need to " eject" eventually to create your own native builds. CaveatsBecause 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. Install Android StudioDownload and install Android Studio. In either case, please make sure to carefully follow the next few steps. If you're already familiar with Android development, there are a few things you may need to configure.

Building a React Native app with native code, however, requires the Android 10 (Q) SDK in particular. Install the Android SDKAndroid Studio installs the latest Android SDK by default. Intel X86 Emulator Accelerator In Download And InstallReact Native Command Line InterfaceReact Native has a built-in command line interface. You can find the actual location of the SDK in the Android Studio "Preferences" dialog, under Appearance & Behavior → System Settings → Android SDK. Verify that ANDROID_HOME has been set by running echo $ANDROID_HOME and the appropriate directories have been added to your path by running echo $PATH.Please make sure you use the correct Android SDK path. If you're using another shell, you will need to edit the appropriate shell-specific config file.Type source $HOME/.bash_profile for bash or source $HOME/.zprofile to load the config into your current shell. Look for and expand the "Android SDK Build-Tools" entry, then make sure that 29.0.2 is selected and check the "Android SDK Command-line Tools (latest)".Finally, click "Apply" to download and install the Android SDK and related build tools.You can also run the following command after setting ANDROID_HOME.Export ANDROID_HOME = $HOME /Library/Android/sdk export PATH = $PATH : $ANDROID_HOME /emulator export PATH = $PATH : $ANDROID_HOME /tools export PATH = $PATH : $ANDROID_HOME /tools/bin export PATH = $PATH : $ANDROID_HOME /platform-tools Copy.bash_profile is specific to bash. This can be either a physical Android device, or more commonly, you can use an Android Virtual Device which allows you to emulate an Android device on your computer.Either way, you will need to prepare the device to run Android apps for development. Let's create a new React Native project called "AwesomeProject":Npx react-native init AwesomeTSProject -template react-native-template-typescript Copy Preparing the Android deviceYou will need an Android device to run your React Native Android app. You can access it without installing anything globally using npx, which ships with Node.js. Creating a new applicationIf you previously installed a global react-native-cli package, please remove it as it may cause unexpected issues.React Native has a built-in command line interface, which you can use to generate a new project. With npx react-native , the current stable version of the CLI will be downloaded and executed at the time the command is run. At this point you should be able to click on the green triangle button next to your AVD to launch it, then proceed to the next step. Select "Create Virtual Device.", then pick any Phone from the list and click "Next", then select the Q API Level 29 image.Click "Next" then "Finish" to create your AVD. Look for an icon that looks like this:If you have recently installed Android Studio, you will likely need to create a new AVD. /AwesomeProject/android, you can see the list of available Android Virtual Devices (AVDs) by opening the "AVD Manager" from within Android Studio. Using a virtual deviceIf you use Android Studio to open. Open Xcode, then choose "Preferences." from the Xcode menu. Command Line Tools #You will also need to install the Xcode Command Line Tools.
