Make sure you’re either running Metro (run ‘npx react-native start’) or that your bundle ‘index.android.bundle’ is packaged correctly for release.

generate index.android.bundle

To generate the index.android.bundle file for your React Native app in Android Studio, follow these steps:

  1. Open a Terminal or Command Prompt:
  • Navigate to your project’s root directory using the terminal or command prompt.
  1. Run the Following Command:
  • Execute the following command to generate the index.android.bundle file:
    react-native bundle --platform android --dev false --entry-file index.js --bundle-output android/app/src/main/assets/index.android.bundle --assets-dest android/app/src/main/res/
  • This command will create the bundle file and place it in the specified location.
  1. Build Your App:
    • After generating the bundle, you can proceed with building your app using Android Studio or by running the following command:
      cd android && ./gradlew assembleRelease
    • This will create the APK file for your React Native app.
