I've created an app in react-native. I need the package name to be: com.org.appname
React-native does not allow you to specify this as the package name in the init, or to change it after init.
react-native init --package="com.org.appname" does not work
Changing the package name as described in Change package name for Android in React Native also doesn't work and results in the following error on react-native run-android
Failed to finalize session : INSTALL_FAILED_VERSION_DOWNGRADE
in iOS project you just need to change BundleID with Xcode.
In Android project you need to change package name in 4 files:
android/app/src/main/java/com/reactNativeSampleApp/MainActivity.java android/app/src/main/java/com/reactNativeSampleApp/MainApplication.java android/app/src/main/AndroidManifest.xml android/app/build.gradle good practice is also to modify BUCK file in Android project, in two places, and correspondingly adjust hierarchy in android project, although it is not necessary:
BUCK file:
android_build_config( name = "build_config", package = "app.new.name", ) android_resource( name = "res", package = "app.new.name", res = "src/main/res", ) run command ./gradlew clean
According to this https://saumya.github.io/ray/articles/72/, you can run this command from the start
react-native init MyAwesomeProject -package "com.example.app" But if you already generated your app via
react-native init MyAwesomeProject You can modify app name in file
android/app/src/main/res/values/strings.xml Then you can modify package name in files
android/app/src/main/java/com/reactNativeSampleApp/MainActivity.java android/app/src/main/java/com/reactNativeSampleApp/MainApplication.java android/app/src/main/AndroidManifest.xml ( optional as per my experience ) android/app/build.gradle Lastly, run the following commands (from inside the app's android/ directory)
./gradlew clean ./gradlew assembleRelease To change iOS version package name, use Xcode
-package option is not supported, does not work and the article in the link is incorrect in other ways, suggest removing it.I use the react-native-rename npm package.
Install using
npm install react-native-rename -g Then from the root of your React Native project execute the following
react-native-rename "MyApp" -b com.mycompany.myapp If your text editor able to replace a string in all of your project files it is very easy to change package id.
I am using PhpStorm and I just replaced my old.package.id with new.package.id in all of my project files. It worked for me
simply just change your package name in these 4 files
android => app => src => main => java => com => reactNativeSampleApp => MainActivity.java & MainApplication.java android => app => src => main => AndroidManifest.xml android => app => build.gradle
