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.
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 ( 
), or on later versions of Android Studio, the three vertical dots, then the Appearance sub-menu.
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.
com.example.test to com.example
com.example.test to com.example and then delete com.example.test.
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.
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:
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
com.example.sample to com.example using other answers
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 :)
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.
Right-click on the package at the Project Panel.
Choose Refactor -> Rename from the context menu.
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.
Source:
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!
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:
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).
I have seen the top voted answers but i found is a little bit different to do this, i try to do the most complete tutorial.
From the Android Studio click over the gear icon ( ) and then select the option: "Compact Empty Middle Packages", to see the folders separated in a tree view.
Now select the folder, click right button to open the contextual menu, select Refactor and then Rename
You will be advised to refactor the package:
Then a window will show the coincidences inside the proyect, select "Do Refactor":
We don´t have to change manually the AndroidManifest.xml or build.gradle files, Refactoring the package will do the job!.
Select the package that will be refactored. Refactor → Move → "Move xxx to new package".
IntelliJ IDEA has an option called "Compact Empty Middle Packages". Select the option icon of the Project tab and de/activate this.
See: How can I change top level package name in IntelliJ IDEA?
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
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...
If this plugin helps you or there is an error, contact me through the following GitHub
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.
If your package name is more than two dot separated, say com.hello.world and moreover, you did not put anything in com/ and com/hello/. All of your classes are putting into com/hello/world/, you might DO the following steps to refactoring your package name(s) in Android Studio or IntelliJ:
com/, com/hello/). You can achieve this by first add two files to package com.hello.world, saycom.hello.world.PackageInfo1.java com.hello.world.PackageInfo2.java
then refactor them by moving them to com and com.hello respectively. You will see com and com.hello sitting there at the Project(Alt+1 or Command+1 for shortcut) and rename directories refactoring is waiting there as you expected.
Refactor to rename one or more of these directories to reach your aim. The only thing you should notice here is you must choose the directories rather than Packages when a dialog ask you.
If you've got lots of classes in your project, it will take you a while to wait for its auto-scan-and-rename.
Besides, you need to rename the package name inside the AndroidManifest.xml manually, I guess, such that other names in this file can benefit the prefix.
[ALSO], it might need you to replace all com.hello.world.R to the new XXX.XXX.XXX.R(Command+Shift+R for short)
Rebuild and run your project to see whether it work. And use "Find in Path" to find other non-touch names you'd like to rename.
Be sure to go to Sheharyar's great Answer. There are so many answers and comments that follow it that it would be easy to get confused and give up, but don't. That answer works.
In short, you do three things:
(1) Deselect Compact Empty Middle Packages.
(2) Refactor then Rename each old directory node by choosing Change Package (not Change Directory) to match the new package name. (Be sure to do a preview of changes.)
(3) Edit the build.gradle file and make APPLICATION_ID match the new package name.
I've found a way easier solution to this problem which also changed the generated imports like com.test.testpackagechange.R and only takes about a minute.
Your first step is to open Android Studio and open the replace all window (Mac: cmd + shift + R, Windows I assume: ctrl + shift + R). Type in your old package name and in the one below your new package name. Click Find. This may take a while because it is also looking through the generated items. If it has over 1000 hits, just click continue.
After you've done that push Replace All to replace your old package name with your new one.
Now close Android Studio and go to Finder on Mac or Windows Explorer on Windows. Change the name of the folders to your new package name, like this:
Now open Android Studio again. Gradle will sync and your package name should be changed to the new one.
I've found this to be the easiest one and the one that covers all areas like generated files.
The common mistake that one can make is one cannot rename the package structure i.e. it is not possible to change com.name.android to com.Renamed.android when one tries to modify at the com.name.android level.
In order to have the same desired change go one level up i.e com.name and here when you refactor change it to Renamed. This will work always.
Your package name will be changed from all the Java files and the manifest file. You have to manually change the package name from build.gradle.
Packages serve two purposes. One is to uniquely identify your app in the Google Play Store. The other is to name the package for the R.java class which is generated when you build your project. You can think of the first purpose as the external package and the second as the internal package. Assuming you want to change the external package so you can identify in the Play store, there's a convenient way to do this.
In Android Studio,
choose File -> Project Structure -> Choose your app's module -> Click on the Flavors tab -> change the Application id. Now, when you build your project, your APK and manifest will use this new package name.
I found another way that works or an extra step to some of the answers here especially if you want to change the domain as well. It works in Android Studio 1.4. This is what I did:
build.gradle file and change the Application Id in defaultConfig to the same name as in manifest and rebuild the project.So for example if you want to rename "com.example.app" to "com.YourDomain.app", open a file under the package to be renamed, in the package breadcrumbs, set your cursor to "example" part of the domain and hit Shift + F6 and rename package to "YourDomain".
I tried the two top-voted solutions but found some issues even though both work to some extent.
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.

OK I have been struggling with cloning & renaming projects in Android Studio, but finally I achieved it. Here are the steps to follow:
That's it...
How to rename com.example.app to com.android.app:
in package com.example.app select example
Shift + F6
choose rename package
rename example to android
confirm do refactor
The best way is to write the new package name and drag from the older package name.
The second way, if you click Refactor then move option then rename the package name, it will rename the package name and then rebuild.
In Build.gradle you have to do manually, if you Refactor then it will not rename in Build.gradle.
Right click on package -> refactor and change the name.
You can also change it in the manifest. Sometimes if you change the package name, but after creating the .apk file it shows a different package name. At that time check "applicationId" in the build.gradle file.
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 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:)
There are many answers given, but still, I am giving my attempt.
Step 1 : As Show in the fig above select the Setting Option... 
Step 2: Select Compact Middle Packages option... 
Step 3: Now Expand the package as shown 
Step 4: After expanding it will look something like 
Step 5: Select any on the subpackage (in or example or googledevsmsverify) and click Shift+f6 button... 
I selected middle package example so it will display as above fig simple rename the package and click on the refactor button
Step 6: you will see the following screen after clicking Refactor button, click on the DO Refactor, and wait until build the gradle... 
Step 7: Goto build.gradle(Mobile:app) and change the package name of applicationID as shown 
Step 8: Just check the package in the manifest.xml file...
All Done the package is change...@Ambilpura
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.
