Encountering the error message “Could not get BatchedBridge, make sure your bundle is packaged properly” while starting a React Native app can be a frustrating experience. This issue often arises when developing on Android devices, particularly those running older versions such as Android 4.4.2. This guide will walk you through effective solutions to resolve this error and get your app running smoothly.
Understanding the Issue
The error typically indicates a problem with how the JavaScript bundle is packaged and served to the app. When the app cannot access the bundled JavaScript, it fails to initiate, leading to the BatchedBridge error.
Step-by-Step Solutions
Solution 1: Bundle the Application
A common solution involves manually bundling your application. Follow these steps:
- Navigate to your project directory:
$ cd myproject - Start the React Native bundler in the background:
$ react-native start > /dev/null 2>&1 & - Generate the bundle file:
$ curl "http://localhost:8081/index.android.bundle?platform=android" -o "android/app/src/main/assets/index.android.bundle" - If the
assetsdirectory does not exist, create it. - Build the app:
$ (cd android/ && ./gradlew assembleDebug) - Install the APK on your device from
android/app/build/outputs/apk/app-debug.apk
Automate this process by adding a script to your package.json:
"scripts": {
"build": "(cd android/ && ./gradlew assembleDebug)",
"start": "node node_modules/react-native/local-cli/cli.js start",
"bundle-android": "react-native bundle --platform android --dev false --entry-file index.android.js --bundle-output android/app/src/main/assets/index.android.bundle --sourcemap-output android/app/src/main/assets/index.android.map --assets-dest android/app/src/main/res/"
},
Solution 2: Resetting the Packager
If the issue persists, try resetting the packager:
- Force kill the app on your device.
- Run
react-native startin your terminal. - Reopen the app from your device.
If using a USB connection, execute adb reverse tcp:8081 tcp:8081 to ensure proper communication between your device and the development server.
Solution 3: Configuring Developer Settings
On physical devices, it may be necessary to configure the developer settings:
- Shake your device to open the Developer menu.
- Select Dev Settings and configure the Debug server host & port for device with your computer’s IP address and port 8081.
