Change package name for Android in React Native

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?

Solution

  • 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
