Change App Package Name

To change the app package name in your Android project, follow these steps:

1. Locate the Existing Package Name

First, you need to find the existing package name of your app:

• Open your project in Android Studio.

• Navigate to the file android/app/src/main/AndroidManifest.xml.

• At the top of the file, you will see the current package name. It will look something like this:

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

  In this case, the current package name is com.example.myapp.

2. Replace the Package Name in Android Studio

To change the package name:

• Right-click on the project folder in Android Studio (this is the root folder of your project).
• Click on Replace in Path.
• A pop-up window will appear with two input boxes:
  • In the "Find" field, enter the existing package name (e.g., com.example.myapp).
  • In the "Replace with" field, enter your new preferred package name (e.g., com.newpackage.myapp).
• Click the Replace All button.

3. Modify the Package in Project Files

• After you’ve replaced the package name, manually check and modify the following files:

• Make sure the <manifest> tag in android/app/src/main/AndroidManifest.xml reflects the new package name:

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