Change package name for Android in React Native

Question

I used react-native init MyApp to initialise a new React Native app. This created among others an Android project with the package com.myapp.

What's the best way to change this package name, for example to: com.mycompany.myapp?

I tried changing it in AndroidManifest.xml but it created other errors, so I'm assuming it's not the way.

Any idea?

Left click on package name and go for Refactor--> Rename option to rename package name. — kunal, Commented May 23, 2016 at 11:41
The pragmatic approach: 1- npx react-native init MycompanyMyapp, 2- Change only the applicationId "com.mycompany.myapp" in android/app/build.gradle. "However, the application ID and package name are independent of each other" – developer.android.com/studio/build/application-id — eightyfive, Commented Mar 29, 2020 at 18:14

I've renamed the project' subfolder from: "android/app/src/main/java/MY/APP/OLD_ID/" to: "android/app/src/main/java/MY/APP/NEW_ID/"

Then manually switched the old and new package ids:

In: android/app/src/main/java/MY/APP/NEW_ID/MainActivity.java:

package MY.APP.NEW_ID;

In android/app/src/main/java/MY/APP/NEW_ID/MainApplication.java:

package MY.APP.NEW_ID;

In android/app/src/main/AndroidManifest.xml:

package="MY.APP.NEW_ID"

And in android/app/build.gradle:

applicationId "MY.APP.NEW_ID"

In android/app/BUCK:

android_build_config(
  package="MY.APP.NEW_ID"
)
android_resource(
  package="MY.APP.NEW_ID"
)

Gradle' cleaning in the end (in /android folder):

./gradlew clean

I had error "Failed to finalize session : INSTALL_FAILED_UPDATE_INCOMPATIBLE" until I manually forced cleaning of the android device simulator: adb uninstall my.package.name ... So directions are fine, but android simulator can "hold on" to old info in a bad way that makes it look like directions don't work. (And simply uninstalling the app did NOT fix this!)

To change the package name from com.myapp to: com.mycompany.myapp (for example),

For iOS app of the react app, use xcode - under general.
For the android app, open the build.gradle at module level. The one in the android/app folder. You will find

// ...
defaultConfig {
     applicationId com.myapp
     // ...
}
// ...

Change the com.myapp to whatever you need.

Hope this helps.

you can simply use 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

react-native-rename on npm

but notice that, this lib remove your MainActivity.java and MainApplication.java. before changing your package name, give a backup from this two file and, after changing package name just put it back to their place. this solution work for me

Goto Android studio

Right click your package (most probably com)-> Refractor -> Rename -> Enter new package name in the dialog -> Do Refractor

It will rename your package name everywhere.

In VS Code, press Ctrl + Shift + F and enter your old package name in 'Find' and enter your new package in 'Replace'. Then press 'Replace all occurrences'.

Definitely not the pragmatic way. But, it's done the trick for me.

This isn't enough (well, maybe it is, if you're using Expo). You also have to rename the folders under android/app/src/main/java and android/app/src/debug/java. The folder structure is e.g. com/acme/awesomeapp, and reflects the package name structure.

@ChristianDavén +1 I'd just like to add that I had an unpublished app with the package name, say, com.myApp & then I replaced all instances of it with com.myNewApp and nothing broke. It would be prudent to rename the folders as you suggest, but that's not a hard requirement. Should you rename? Yes. Do you have to? No.

If you are using Android Studio-

changing com.myapp to com.mycompany.myapp

create a new package hierarchy com.mycompany.myapp under android/app/src/main/java
Copy all classes from com.myapp to com.mycompany.myapp using Android studio GUI
Android studio will take care of putting suitable package name for all copied classes. This is useful if you have some custom modules and don't want to manually replace in all the .java files.
Update android/app/src/main/AndroidManifest.xml and android/app/build.gradle (replace com.myapp to com.mycompany.myapp
Sync the project (gradle build)

atulmy · Accepted Answer · 2018-08-18 17:18:42Z

The init script generates a unique identifier for Android based on the name you gave it (e.g. com.acmeapp for AcmeApp).

You can see what name was generated by looking for the applicationId key in android/app/build.gradle.

If you need to change that unique identifier, do it now as described below:

In the /android folder, replace all occurrences of com.acmeapp by com.acme.app

Then change the directory structure with the following commands:

mkdir android/app/src/main/java/com/acme

mv android/app/src/main/java/com/acmeapp android/app/src/main/java/com/acme/app

You need a folder level for each dot in the app identifier.

I have a solution based on @Cherniv's answer (works on macOS for me). Two differences: I have a Main2Activity.java in the java folder that I do the same thing to, and I don't bother calling ./gradlew clean since it seems like the react-native packager does that automatically anyways.

Anyways, my solution does what Cherniv's does, except I made a bash shell script for it since I'm building multiple apps using one set of code and want to be able to easily change the package name whenever I run my npm scripts.

Here is the bash script I used. You'll need to modify the packageName you want to use, and add anything else you want to it... but here are the basics. You can create a .sh file, give permission, and then run it from the same folder you run react-native from:

rm -rf ./android/app/src/main/java


mkdir -p ./android/app/src/main/java/com/MyWebsite/MyAppName
    packageName="com.MyWebsite.MyAppName"
    sed -i '' -e "s/.*package.*/package "$packageName";/" ./android/app/src/main/javaFiles/Main2Activity.java
    sed -i '' -e "s/.*package.*/package "$packageName";/" ./android/app/src/main/javaFiles/MainActivity.java
    sed -i '' -e "s/.*package.*/package "$packageName";/" ./android/app/src/main/javaFiles/MainApplication.java
    sed -i '' -e "s/.*package=\".*/    package=\""$packageName"\"/" ./android/app/src/main/AndroidManifest.xml
    sed -i '' -e "s/.*package = '.*/  package = '"$packageName"',/" ./android/app/BUCK
    sed -i '' -e "s/.*applicationId.*/    applicationId \""$packageName"\"/" ./android/app/build.gradle

    cp -R ./android/app/src/main/javaFiles/ ./android/app/src/main/java/com/MyWebsite/MyAppName

DISCLAIMER: You'll need to edit MainApplication.java's comment near the bottom of the java file first. It has the word 'package' in the comment. Because of how the script works, it takes any line with the word 'package' in it and replaces it. Because of this, this script may not be future proofed as there might be that same word used somewhere else.

Second Disclaimer: the first 3 sed commands edit the java files from a directory called javaFiles. I created this directory myself since I want to have one set of java files that are copied from there (as I might add new packages to it in the future). You will probably want to do the same thing. So copy all the files from the java folder (go through its subfolders to find the actual java files) and put them in a new folder called javaFiles.

Third Disclaimer: You'll need to edit the packageName variable to be in line with the paths at the top of the script and bottom (com.MyWebsite.MyAppName to com/MyWebsite/MyAppName)

Muhammad Haidar · Accepted Answer · 2021-07-02 12:51:14Z

To change the Package name you have to edit four files in your project :

 1. android/app/src/main/java/com/reactNativeSampleApp/MainActivity.java
 2. android/app/src/main/java/com/reactNativeSampleApp/MainApplication.java
 3. android/app/src/main/AndroidManifest.xml
 4. android/app/build.gradle

The first 2 files have the package name as something like below.

 package com.WHATEVER_YOUR_PACKAGE_NAME_IS;

Change it to your desired package name.

 package com.YOUR_DESIRED_PACKAGE_NAME;

You have to also edit the package name in 2 other files.

  android/app/build.gradle

  android/app/src/main/AndroidManifest.xml

Note if you have a google-services.json file in your project then you have to also change your package name in that file.

After this, you have to ./gradlew clean your project.

There are a lot of bad answers here

if you want to change the package name, go to your build.gradle in app

 defaultConfig {
        applicationId "your.new.package.name" //change this line

then when running the app from the command line, pass in the new package name as an arg

react-native run-android --appId your.new.package.name

There's no need to rename your whole project

In case, you are fine with creating new react-native project, and migrate your code there, you can simply do it using:

npx react-native init --package-name com.yourcompany.yourapp yourappname

, which will also setup the required and respective nested folder structure based on your custom package name. Then you can proceed with migrating your code there. It has worked in my case.

Go to Android Studio, open app, right click on java and choose New and then Package.

Give the name you want (e.g. com.something).

Move the files from the other package (you want to rename) to the new Package. Delete the old package.

Go to your project in your editor and use the shortcut for searching in all the files (on mac is shift cmd F). Type in the name of your old package. Change all the references to the new package name.

Go to Android Studio, Build, Clean Project, Rebuild Project.

Done!

Happy coding :)

Vaibhav Mojidra · Accepted Answer · 2021-12-10 19:40:52Z

I will provide you step by step procedure.

First of all, we need to understand why we need to rename a package? Mostly for uniquely identifying App right? So React Native is a cross-platform to develop an app that runs on both iOS and Android. So What I recommended is to need the same identifier in both the platforms. In case Android Package Name is a unique identifier of your App and for iOS its bundle ID.

Steps:

Firstly close all editors/studio eg: xcode android studio vscode and then Install package "react-native-rename" in the terminal by running the command (Keep your project folder copy in another folder for backup if you don't feel this safe):

npm install react-native-rename -g

After sucessfully installing package open your project folder in the terminal and hit the below command where "Your app name Within double quotes" is app name and <Your Package Name without double/single quotes> is replaced with package/bundle name/id:

react-native-rename "< Your app name Within double quotes >" -b <Your Package Name without double/single quotes>

Example: react-native-rename "Aptitude Test App" -b com.vaibhavmojidra.aptitudetestapp

Note Make sure the package/bundle name/id is all in small case

This is not yet done yet now every file will change where the it had bundle/package names except one in ios project which we manually need to do for that open the xcode>open a project or file> choose file from projectfolder/ios/projectname.xcodeproj and click open
Click on your projectname.xcodeproj that is first file in the project navigator then in field of Bundle identifier enter the package name/Bundle ID as below:

After that run in the terminal

cd ios

Then run

pod install

Then run

cd ..

Now you are done for all the changes for ios just last step is to open Android Studio>Open an Existing Project> select projectfolder/android folder > Click on open
Let it load and complete all the process and then in the Build Menu click "Clean Project" and the in File Menu > Close Project
Close All editors and Now You can try the commands to run project on ios and android it will run with renamed packaged just while start server add extra flag --reset-cache:

npm start --reset-cache

Enjoy it will work now

this is just the best answer for this issue.

Please double check this android/app/build.gradle

For android you have to go to app => src => main => jni folder

In MainApplicationTurboModuleManagerDelegate.h

change below line

static constexpr auto kJavaDescriptor =

Works, But it requires addition steps.. You also needs to change the "com.app" in each file inside "newarchitecture" folder

I just learned this today but adding this answer to help others. You just need to add a namespace to the app/build.gradle that references the old name, like this:

defaultConfig {
  applicationId "com.mycompany.myapp"
  namespace "com.myapp"
}

Then you can have a bash script that changes the applicationId with something like this:

function sedi {
  if [ "$(uname)" == "Linux" ]; then
    \sed -i "$@"
  else
    \sed -i "" "$@"
  fi
}

bundle_name=com.mycompany.myapp

sedi -E "s/applicationId \"[-0-9a-zA-Z._]*\"/applicationId \"${bundle_name}\"/" android/app/build.gradle

React [email protected] Tried to rename package name from com.x to com.y.z

I got through this painful process by doing these:

Change displayName in app.json to z.

{
  "name": "<THIS_SHOULD_STAY_SAME>",
  "displayName": "<Z>"
}

Change the content of the string app_name in strings.xml

<resources>
  ...
  <string name="app_name"><Z></string>
  ...
</resources>

Search through your react-native project for com.x and replace all com.x with com.y.z

!important: In case you're using external services, and in case if you're generated a file and put it under /android you may want to make sure the services that you're using will still work. I recommend you to generate a new config file(s) using your new package name com.y.z and put it after the finishing the steps described below.

Update the folder structure to this:

old: .../android/app/src/main/java/com/x
new: .../android/app/src/main/java/com/y/z

Move all the files under .../android/app/src/main/java/com/x to .../android/app/src/main/java/com/y/z.
Clean up.

  $ ./gradlew clean

Build.

  $ react-native run-android

In my case,

I need to change the package com.yourProjectName to boonagency.connachttribune

So then I just do that:-

yourApp/android/app/build.gradle

  defaultConfig {
  applicationId "com.connachtapp"
  minSdkVersion rootProject.ext.minSdkVersion
  targetSdkVersion rootProject.ext.targetSdkVersion
  versionCode 1
  versionName "1.0"

to

    defaultConfig {
    applicationId "boonagency.connachttribune"
    minSdkVersion rootProject.ext.minSdkVersion
    targetSdkVersion rootProject.ext.targetSdkVersion
    versionCode 1
    versionName "1.0"

yourProjectName/android/app/src/main/AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.connachtapp">

to

  <manifest xmlns:android="http://schemas.android.com/apk/res/android"
   package="boonagency.connachttribune">

change folder name

yourProjectName/android/app/src/main/java/com/connachtapp

to

 yourProjectName/android/app/src/main/java/boonagency/connachtapp

yourProjectName/android/app/src/main/java/boonagency/connachtapp/MainApplication.java

package boonagency.connachttribune; // change here
...
import boonagency.connachttribune.newarchitecture.MainApplicationReactNativeHost; // change here
...
 Class<?> aClass = Class.forName("boonagency.connachttribune.ReactNativeFlipper"); // change here

yourProjectName/android/app/src/main/java/boonagency/connachtapp/MainActivity.java
```
package boonagency.connachttribune; // change here
```
yourProjectName/android/app/src/main/java/boonagency/connachtapp/newarchitecture/MainApplicationReactNativeHost.java

yourProjectName/android/app/src/main/java/boonagency/connachtapp/newarchitecture/modules/MainApplicationTurboModuleManagerDelegate.java
```
package boonagency.connachttribune.newarchitecture.modules; // change here
```
yourProjectName/android/app/src/main/java/boonagency/connachtapp/newarchitecture/components/MainComponentsRegistry.java
```
package boonagency.connachttribune.newarchitecture.components; // change here
```

last just run

cd android && ./gradlew clean && cd .. && npm run android

To change the Package name in a react-native android project, you must do the following exactly

android/app/src/main/java/com/reactNativeSampleApp/MainActivity.java, search old package name, replace with new
android/app/src/main/java/com/reactNativeSampleApp/MainApplication.java, search old package name, replace with new
android/app/build.gradle, search old package name, replace with new
Under app>src>main>java, create a folder that matches the new package name and copy the old files into the last folder
Under app>src>release>java, create a folder that matches the new package name and copy the old files into the last folder
In the last step, change the old package name of the 'ReactNativeFlipper.java' which is the last file in the new folder to the new package name

For ios project, you can achieve that with a click on xcode.
