When developing a React Native application, you may find yourself needing to change the package name of your Android project. This could be for reasons such as rebranding or aligning with company naming conventions. However, changing the package name requires careful attention to ensure all references are updated to avoid build errors. Here’s a comprehensive guide to help you through the process.
Step-by-Step Guide
Manual Method
If you prefer a hands-on approach, you can manually change the package name by following these steps:
- Navigate to the directory:
android/app/src/main/java/MY/APP/OLD_ID/and rename it toandroid/app/src/main/java/MY/APP/NEW_ID/. - Open
MainActivity.javaandMainApplication.javafiles located inandroid/app/src/main/java/MY/APP/NEW_ID/and update the package declaration topackage MY.APP.NEW_ID;. - Edit the
AndroidManifest.xmlfile inandroid/app/src/main/and update the package attribute:package="MY.APP.NEW_ID". - In the
build.gradlefile located atandroid/app/, update theapplicationId:applicationId "MY.APP.NEW_ID". - If your project uses
BUCK, update the package inandroid/app/BUCK: - Finally, clean the Gradle build by running
./gradlew cleanin the/androiddirectory.
android_build_config(
package="MY.APP.NEW_ID"
)
android_resource(
package="MY.APP.NEW_ID"
)Using the React Native Rename Tool
For a more streamlined approach, you can use the react-native-rename npm package:
- Install the tool globally using
npm install react-native-rename -g. - From the root of your React Native project, execute:
react-native-rename "MyApp" -b com.mycompany.myapp. - Note that this tool might remove
MainActivity.javaandMainApplication.java. Ensure you back up these files before running the command and restore them afterward.
Additional Considerations
After changing the package name, make sure to update any other files that might reference the old package name, such as google-services.json if you are using Firebase. Also, ensure that all paths and imports within your Java files are correctly updated to reflect the new package structure.
