Last updated on: March 24, 2021

Today, I’m going to show you how to change your project name and package name in your project very easily!

Let’s dive right into it!

Change the Project Name

Change the name of your project by closing the Android Studio, go to your project folder, rename it…

Open the settings.gradle file with a text editor, like VSCode, and change the rootProject.name to your new project name.

Done! Project name has been changed! Just open your project with the Android Studio and Gradle will sync again.

Change the App Name

Usually, when you change the project name, you wanna change the name of your app too.

Go to the res folder > values > strings.xml and change the app_name to your new name.

Change the Package Name

To rename your package name, all you have to do is go to your AndroidManifest.xml file, 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 is usually in format com.domain.appname, in this example, we changed the appname part, but you can do the same steps for the domain.

Last, go to your module-level build.gradle file and change the package name in applicationId

Done! Package name has changed!

How to change app name in Android Studio

I’m trying to learn how to build a simple app in Android just to satisfy my curiosity. This will also be a very handy skill because I use Android phones often, and there are times that the apps I download from Google Play Store lack features that I need.

This will be a very simple guide on how to change app name in Android Studio, something that most beginners in Android development probably want to know.

It is assumed in this guide that you have prior knowledge in coding.

The app name that I’m referring to is the one that says “My Application”, as marked on the image below:

How to Rename Package Name in Android Studio?

A package is a namespace that combines a set of relevant classes and interfaces. Conceptually one can consider packages as being similar to various folders on your computer. One might have HTML pages in one folder, images in another, and scripts or applications in yet another. Because in android, software written in the Java/Kotlin programming language can be made of hundreds or thousands of different classes, it makes sense to keep things organized by placing related classes and interfaces into packages.

A package is basically the directory (folder) in which source code resides. Normally, this is a directory structure that uniquely distinguishes the android application; such as com.example.app. Then the developer can build packages within the application package that divides the code; such as com.example.app.ui or com.example.app.data. The package for each android application resides within the src/main/java directory of the application module. The developer could put a different package within the application package to separate each “layer” of the application architecture.

There might be many situations when the developer wants to change the package name of the App in Android Studio. The developer might have download source code from the internet and requires to rename the package name according to his/her Application details. Here in this article, we are going to discuss step by step how to rename/change package name in Android Studio:

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.

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

How to change project name on Android Studio 3+

How can I change the project name of an Android project after it has been created while not breaking anything

1 Answer 1

Most answers addressing this question are somehow outdated and does not work with the Android Studio 3+ version. This is what works for me and should work if you wish to change the project name (name of the project root folder, usually located at the directory C:/. /AndroidStudioProjects on your computer), application ID (the name used to identify your app on Play Store).

Note that you cannot change an app’s application ID after it has been published to Play Store, except if you want to create another application using the same code (i.e., changing the ID after Play Store publication would cause Play Store to assume the app is a different one than the one bearing the previous application ID even if they offer the same functionality)

To change application ID is easier, just change the attribute of : 1. applicationId in build.grade(Module) to the new application ID you want 2. app_name in strings.xml to the new application ID you want 3. Ensure the value of android:label in AndroidManifest.xml is set to «@string/app_name»

To rename any other file in your project on Android Studio, simply right click on the file on the project directory (usually the pane on the top left of Android Studio), select refactor>>rename file. Ensure you keep these boxes checked search for references and search in comments and strings

Trending sort is based off of the default sorting method — by highest score — but it boosts votes that have happened recently, helping to surface more up-to-date answers.

It falls back to sorting by highest score if no posts are trending.

First click once on your package and then click setting icon on Android Studio.

Close/Unselect Compact Empty Middle Packages

Then, right click your package and rename it.

In projects that use the Gradle build system, what you want to change is the applicationId in the build.gradle file. The build system uses this value to override anything specified by hand in the manifest file when it does the manifest merge and build.

For example, your module’s build.gradle file looks something like this:

applicationId is the name the build system uses for the property that eventually gets written to the package attribute of the manifest tag in the manifest file. It was renamed to prevent confusion with the Java package name (which you have also tried to modify), which has nothing to do with it.
