Rename package in Android Studio

How do you rename packages in the new IDE Android Studio, based on IntelliJ IDEA?

Is there an automatic refactoring included?

I want to make bulk refactoring, but I don't know how. I worked two years with Eclipse and in Eclipse it's a one-click operation.

Android Studio 2024

Step by Step Implementation

Step 1: To rename package name in Android studio open your project in Android mode first as shown in the below image.

Step 2: Now click on the setting gear icon and deselect Compact Middle Packages.

Step 3: Now the packages folder is broken into parts as shown in the below image.

Step 4: Now right-click on the first package name (com) and Refactor > Rename. A warning message will be displayed but go ahead and click on the Rename current button.

Step 5: Rename the directory name as your requirement and click on the Refactor button.

Note: Go to Build > Rebuild Project to display the updated name.

Now you can see your directory name changes from com -> gfg as shown in the below image.

Step 6: Do the same for the domain extension and App folder name according to your requirement.

Now you can see the package name has been changed from com.example.pulltorefreshwithlistview to gfg.geeksforgeeks.listview as shown in the below image.

Step 7: Now go to the build.gradle (Module: app) in Gradle Scripts. Here change the applicationId and click on Sync Now. And you are successfully renamed your package name.

Android Studio 2024(Koala) - (Rename package from A.B.Name to A.B.C.Name)

Things changed slightly between versions - so this will probably only be relevant for Android Studio - Koala

Make a complete backup of your project as it is (I tried multiple times before finding a working solution)
Create a new package in the main folder with the name you would like to use: (Convention is to use your website address in reverse)
Select the main directory for your new package:

Type your new package name and press enter.

Select the contents of your existing package and drag it to the new one:

Confirm the move:

If you have multiple folders, after the move it might come up with the same move window again and selecting ok might show an error. Just close this window.

Next delete the old package (the old package should be empty by now)

Next select the top folder of the project

Click on Edit->Find->Replace in Files

Type your old package name at the top (you might need to use escape characters), your new package name and then select replace all

Clean your build next

Invalidate the cache and restart

Finally if you are using a development device, delete the previous installation from the old device before running debug again.

This is a python script to replace string. I used this to replace package name. of a lib worth 2500+ files. after that I only had to fix R. from android studio

python scrypt.py "C:\Users\yourpath" "stringToreplace" "withString"

import os
import sys

def replace_string_in_file(file_path, search_string, replace_string):
    try:
        with open(file_path, 'r', encoding='utf-8') as file:
            lines = file.readlines()

        updated_lines = [line.replace(search_string, replace_string) for line in lines]

        with open(file_path, 'w', encoding='utf-8') as file:
            file.writelines(updated_lines)
    except UnicodeDecodeError:
        print(f"Could not read file {file_path} due to encoding issues.")

def process_directory(directory, search_string, replace_string):
    for root, dirs, files in os.walk(directory):
        for file in files:
            file_path = os.path.join(root, file)
            replace_string_in_file(file_path, search_string, replace_string)

if __name__ == "__main__":
    if len(sys.argv) != 4:
        print("Usage: python replace_string.py <directory> <search_string> <replace_string>")
        sys.exit(1)

    directory = sys.argv[1]
    search_string = sys.argv[2]
    replace_string = sys.argv[3]

    process_directory(directory, search_string, replace_string)

    print("Replacement complete!")

Another good method is: First create a new package with the desired name by right clicking on the Java folder → *New* → *Package*.

Then, select and drag all your classes to the new package. Android Studio will refactor the package name everywhere.

Finally, delete the old package.

Done.

Very important:

You have to manually change AndroidManifest.xml and build.gradle file to the new package if you use this method.

According to the latest Menu

Compact Middle packages is under Tree Appearance

rest of the steps follow Sheharyar's Answer. (It took some time to find this menu. so adding here to save time)

After making all the changes, rename any file providers that use the package name to avoid conflicts.

If your use case fits the description of a 'variant' or a 'mod' of the original app then you can avoid the hassle of renaming your packages, and can leave alone the namespace and the applicationId, and instead define the applicationIdSuffix in your build.gradle, e.g.:

defaultConfig {
    namespace "com.original.app"
    applicationId "com.original.app"
    versionCode 42
    versionName "0.42"
    applicationIdSuffix '.insidersBuild'
    ################### ^^^^^^^^^^^^^^^^
}

Keep in mind: If you don’t explicitly define the applicationId in your build.gradle's defaultConfig, then the value is inferred from the package attribute in your AndroidManifest.xml.

Changing the application ID (which is now independent of the package name) can be done very easily in one step. You don't have to touch AndroidManifest. Instead do the following:

right click on the root folder of your project.
Click "Open Module Setting".
Go to the Flavours tab (It might also be called Default Config in the newer versions).
Change the applicationID to whatever package name you want. Press OK.

Note this will not change the package name. The decoupling of Package Name and Application ID is explained here: http://tools.android.com/tech-docs/new-build-system/applicationid-vs-packagename

I also had a hard time changing the package name of a project. Especially big projects. It has so much to do, but those jobs are really boring. I've been developing a plugin on IntelliJ IDEA and Android Studio. It will help you to automatically change the package name automatically. It's called Android Package Renamer

Installation

Using IDE built-in plugin system:

Settings/Preferences > Plugins > Marketplace > Search for "Android Package Renamer" > Install Plugin
Manually:

Download the latest release and install it manually using Settings/Preferences > Plugins > ⚙️ > Install plugin from disk...

Usage

Open Your Project.
Click -> File -> Rename Package
Input the Package you want to change.
Click Ok.
Sync Project with Gradle Files or Invalidate Caches

This plugin can rename packages (it can do more):

com.android.example -> org.nickseven.product
com.android.example -> org.nickseven
com.android.example -> org.nickseven.product.native
com.android.etc.nick.d -> org.android.otd.nick.d

If this plugin helps you or there is an error, contact me through the following GitHub

I didn't see anyone point this out, that is why I am writing this answer. I would have added this answer as a comment because it really doesn't deserve to be an answer but I don't have enough reputation points on Stackoverflow to leave a comment.

I was looking to change my package name from com.param.myapp to com.pvs.myapp. I followed every solution on the internet but forgot to change the namespace 'com.param.myapp' to the namespace 'com.pvs.myapp' in build.gradle(:app) in android block. I am not sure if namespace line needed to exist but it was giving me errors. Android Studio was generating classes under the old package name.

Just remember to check it!

In Android Studio, you can do this:

For example, if you want to change com.example.app to my.awesome.game, then:

In your Project panel, click on the little gear icon ( )
Uncheck the Compact Empty Middle Packages option
Your package directory will now be broken down into individual directories
Individually select each directory you want to rename, and:

Right-click on it
Select Refactor
Click on Rename
In the pop-up dialog, click on Rename Package instead of Rename Directory
Enter the new name and hit Refactor
Click Do Refactor in the bottom
Allow a minute to let Android Studio update all changes
Note: When renaming com in Android Studio, it might give a warning. In such case, select Rename All

Now open your Gradle Build File (build.gradle - Usually app or mobile). Update the applicationId in the defaultConfig to your new Package Name and Sync Gradle, if it hasn't already been updated automatically:
You may need to change the package= attribute in your manifest.
Clean and Rebuild.
Done! Anyway, Android Studio needs to make this process a little simpler.

Quick and easy way in 3 steps:

1- open MainActivity or any other java or Kotlin file.

At the top there is the package declaration such as:

package com.example.myapp;

select the package portion that you want to change and press Shift+F6. I personally want to change the example.

In the warning dialog, select Rename package and then insert the desired package name.

2- Open AndroidManifest.xml and inside <manifest> tag change the package to the desired package name.

3- open build.gradle(Module: app) and change the applicationId to the desired package name.

Change the Package Name

To rename your package name, all you have to do is go to your AndroidManifest.xml file and put your mouse cursor in front of the part of the package name you want to change.

Right-Click > Refactor > Rename

In the new window press Rename package

Change name and press Refactor

…and press Do Refactor at the bottom.

Your package name usually is in format com.domain.appname; in this example we changed the appname part, but you can do the same steps for the domain too.

Done! You have changed your package name!

First, you need to go to the settings icon which is Appear in left. Click on that dropdown and uncheck Compact Empty Middle Packages

Go to Your AndroidManifest.xml

Select All of your Package and then Right click there
Refactor and then rename that how you want.
and then go to your build.gradle and then change Applicationid with packagename that what you have in Android Manifest.

It is worked For Me

To rename the package name in Android studio, Click on the setting icon in the project section and untick the Compact empty Middle Packages, after that the package will split into multiple folder names, then right-click on the folder you need to change the name, click on refactor-> Rename-> Type the name you want to change in -> Refactor -> Refactor Directory, then import R.java file in the whole project. Working for me.

THERE ARE TWO THINGS - PACKAGE NAME and APPLICATION ID.

The easiest and most satisfying way for me is this,

Can you see the highlighting line "vijayjangid", it was "example" before. All I did was renamed example using refractor and the android studio did all the work.

FIRST PART DONE.

Now rename the application id in defaultConfig brackets to the same as the name you renamed the example folder. Make sure you rename the package name and id in cloud services like firebase, Aws, realm, etc.

That's it you are done, the most upvoted answer is old, we need to update the answers.

3 Methods to change package name in Android Studio

I think this is a new one. I tried it and it's working. If the above doesn't work for you. Try this. On the site I mentioned above, there are 2 other methods too with image tutorials. I also checked.

First I am going to talk about changing the Package name. In this example, We will change the package name “com.androidride.myapplication” to “info.xyz.yourapplication”.

Right click on the package name you want to change and select Refactor - > Move.
A new dialog appears, Choose Move package “com.androidride.myapplication” to another package and click on Ok.
A warning dialog appears, click on yes.
Enter new package name in the new dialog. But only “info.xyz” leave yourapplication.
Now you will see a warning dialog says Package info.xyz does not exist. Do you want to create it? click on yes.
Click on “Do Refactor”. Now your package name changed to info.xyz.myapplication.
Right click on info.xyz.myapplication and Refactor -> Rename.
Click on Rename package.
Rename dialog: change myapplication to yourapplication.
Click on Do refactor.
Delete old package name directories and change application id in build.gradle, change it into info.xyz.yourapplication.
That's all.

Go to AndroidManifest.xml There you will find the package as the attribute of the manifest tag. Just select the part you want to change, right-click-> refactor -> rename

Maybe earlier it was hard, but as of today, it is not anymore.

You might also want to change the app id in

defaultConfig {
    applicationId 
}

I recommend to use Sublime Text (or Notepad++). Replace com.one.lastname -> com.two.newname and com/one/lastname -> com/two/newname in ...\Projects[MyProject]. And don't forget to rename ...\Projects\MyProject\app\src\main\java\com\one\lastname, ...\Projects\MyProject\app\src\test\java\com\one\lastname and ...\Projects\MyProject\app\src\androidTest\java\com\one\lastname!

That's all:)

The first part consists of creating a new package under the java folder and selecting then dragging all your source files from the old package to this new package. After that, you need to rename the package name in android manifest` to the name of the new package.
In step 2, here is what you need to do. You need to change the old package name in applicationId under the module build.gradle in your android studio in addition to changing the package name in the manifest. So in summary, click on build.gradle which is below the "AndroidManifest.xml" and modify the value of applicationId to your new package name.
Then, at the very top, under build. clean your project, then rebuild. It should be fine from here.

I tried the two top-voted solutions but found some issues even though both work to some extent.

List item: The new package-drag-drop method leaves some unchanged and creates some undesired effects
List item: The rename package only changes the last part of the package name

After some experiments, I found the following method works well for me.

If you just need to change the last part of the package name, use the method outlined by GreyBeardedGeek, namely

Right-click on the package in the Project pane. Choose Refactor -> Rename from the context menu

If you need to change the whole package name, do the following.

Right-click on the package in the Project pane. Choose Refactor -> Move from the context menu

This will create a new package folder (when necessary) but will keep the last part of your package name as before. If you need to change the last part, do the rename accordingly.

Note also that you may need to modify package names in e.g. build.gradle, manifest, and/or any xml resource files, or even in your code if hardcoded. After all that, do Sync/Clean/Rebuild project as necessary.

Open the file:

app → manifests → AndroidManifest.xml

Highlight each part in the package name that you want to modify (don't highlight the entire package name) then:
- Mouse right-click → Refactor → Rename → Rename package
- type the new name and press (Refactor)
Do these steps in each part of the package name.
Open (Gradle Script) >> (build.gradle(Modul:app))

and update the applicationId to your package name
Open the menu (build) and choose (Rebuild Project).

Go to your AndroidManifest.xml file.
Place your cursor in the package name as shown below. Don't select it, just place it.
Then press Shift + F6 and you will get a popup window as shown below. Select Rename package.
Enter your new name and select Refactor. (Note: since my cursor is on "something", only something is renamed.)

That's it done.

The approach used by me for renaming the package name is as follows:-

Step 1 : Select the Project option from the left menu of Android Studio

Step 2 : Right-click on java and add a new package and set the desired package name

Step 3 : Enter your new package name

Step 4 :Copy all the files from your old package and paste into the new package

Step 5 :Rename the package name in the manifest file

Step 6 :Rename the package name in build.gradle file

Step 7 :Then right-click the old package and delete it with all its data, and delete that directory as well

Step 8 :Then Rebuild your project

Step 9 :Then you will find some errors of old import packagename in your project Select the old package name in any file and press CTRL + Shift + R , and enter your new package name in replace box, then press find

Step 10 :Then a popup appears like below and select the All files option from it

Step 11 :Rebuild your project again, bingo your project packagename has been changed :)

The question asked:

Is there an automatic refactoring included?

I want to make bulk refactoring, but I don't know how. I worked two years with Eclipse and in Eclipse it's a one-click operation.

Well, almost one-click with automatic refactoring, but just one small step first, i.e., just the small step to create the new package. Here is the full solution below.

You can rename a package by creating a new package (including the required folder path) and then drag-and-drop over from the old package (and let Android Studio take care of the refactoring of the various references from the old package to the new), as follows:

Right click on java under app.
Select New and Package
Select the location for the new package as ../app/src/main/java
Enter the full name of the new package
The new package will be created. Now, drag-and-drop over from the old package to the new. Preview the refactoring if you'd like to check that Android Studio is doing it properly. If it all looks good, proceed with the refactoring.

NB: since application ID and package name are decoupled these days, note that the above is only for renaming the package name. For changing the application ID, you can do that in your build.gradle.

If your only reason for renaming is to avoid collision with another build (or a system app) with the same package name, then you can instead rename ONLY the applicationId in your app's build.gradle file.

Example: Given that you already have an app installed with the id com.android.phone (which you want to keep) change your app/build.gradle to:

android {
    defaultConfig {
        applicationId "com.android.phone.mymod"

}

I.e. if you already have an app with the package name com.android.phone and don't want/cannot uninstall it (for example because it's a system app and the device is not rooted) then the change above is all that is needed in order to have your app installed side-by-side with the original app. On the device the applicationId is what will be used and not the actual package name. Also your app data will be stored under /data/data/com.android.phone.mymod rather than /data/data/com.android.phone.

^{NB. In certain cases you might also need to rename the names of providers and authorities in your AndroidManifest.xml file.}

Reference:

https://developer.android.com/studio/build/application-id

When you create a new project in Android Studio, the applicationId exactly matches the Java-style package name you chose during setup. However, the application ID and package name are independent of each other beyond this point. You can change your code's package name (your code namespace) and it will not affect the application ID, and vice versa (though, again, you should not change your application ID once you publish your app). However, changing the package name has other consequences you should be aware of, so see the section about how to change the package name.

it will work fine for me

Change Following.

Step 1: Make sure ApplicationId And PackageName will Same. example :

  android {
  defaultConfig {
                     applicationId "com.example.myapplication"
                 }
       }
 and package name the same. package="com.example.myapplication"

Step 2 delete iml file in my case :

  Go To Project> >C:\Users\ashif\Documents\MyApplication  .iml file // delete 
if you forget Project Path Then Go To android Studio Right Click on app and go to  Show in Explorer you get your Project and remove .iml file

Step 3 Close Project

Step 4 Now Copy Your old Project and Paste Any other Root or copy Project Folder and paste Any other Dir.

 Example C:\Users\ashif\Documents/MyApplication

Step 5

Now open Android Studio and open Existing Project 
C:\Users\ashif\Documents/MyApplication

Try it will work

Create a new package in the java directory and move your project into that package. Like your current project id is com.testapp.user and you want to change it xyz.testapp.user. Then create a package in src/java directory named xyz and move your child package testapp.user into xyz. It works for me. Finally, update build.gradle and manifest project id.
