Known Issues

Android builds from the metro bundler terminal

Because of a mess with our multiple build flavors, under RN 0.73 the default way of running android for development is broken so you cannot just press a from the metro bundler terminal to run the app on android.

Instead, run the metro bundler (npm start) on one terminal, and run npm run android on another to build the app.

Afterwards, just press r on the metro bundler terminal to reload the app.

Troubleshooting

Clean Build

# For all platforms
rm -rf node_modules
npm install

# For android
rm -rf android/app/.cxx
(cd android && ./gradlew clean)

# For iOS
rm -rf ~/Library/Caches/CocoaPods
rm -rf ios/Pods
rm -rf ios/Podfile.lock
rm -rf ios/build
(cd ios && RCT_NEW_ARCH_ENABLED=1 pod install)

# For all platforms
watchman watch-del .
watchman watch-project .
npm start -- --reset-cache

"Unable to boot simulator" error for iOS Simulator

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

Getting Started

Note: Make sure you have completed the React Native - Environment Setup instructions till "Creating a new application" step, before proceeding.

Step 1: Start the Metro Server

First, you will need to start Metro, the JavaScript bundler that ships with React Native.

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

# using npm
npm start

# OR using Yarn
yarn start

Step 2: Start your Application

Let Metro Bundler run in its own terminal. Open a new terminal from the root of your React Native project. Run the following command to start your Android or iOS app:

For Android

# using npm
npm run android

# OR using Yarn
yarn android

For iOS

# using npm
npm run ios

# OR using Yarn
yarn ios

If everything is set up correctly, you should see your new app running in your Android Emulator or iOS Simulator shortly provided you have set up your emulator/simulator correctly.

This is one way to run your app — you can also run it directly from within Android Studio and Xcode respectively.
