This is a new React Native project, bootstrapped using @react-native-community/cli.

Getting Started

Note

: Make sure you have completed the Set Up Your Environment guide before proceeding.

Step 1: Install Dependencies

First, install the required dependencies:

# Using npm
npm install

# OR using Yarn
yarn install

Step 2: Start Metro

You will need to run Metro, the JavaScript build tool for React Native.

To start the Metro dev server, run the following command from the root of your React Native project:

# Using npm
npm start

# OR using Yarn
yarn start

Step 3: Build and run your app

With Metro running, open a new terminal window/pane from the root of your React Native project, and use the following command to build and run your Android app:

Android

# Using npm
npm run android

# OR using Yarn
yarn android

Note

: This project is configured for Android development only.

If everything is set up correctly, you should see your new app running in the Android Emulator or your connected Android device.

You can also build it directly from Android Studio.

Step 4: Modify your app

Now that you have successfully run the app, let's make changes!

Open App.tsx in your text editor of choice and make some changes. When you save, your app will automatically update and reflect these changes — this is powered by Fast Refresh.

When you want to forcefully reload, for example to reset the state of your app, you can perform a full reload:

• Android: Press the R key twice or select "Reload" from the Dev Menu, accessed via Ctrl + M (Windows/Linux) or Cmd ⌘ + M (macOS).

Congratulations! 🎉

You've successfully run and modified your React Native App. 🥳
