Android Change Package Name Published App

To change the package name of a published app on the Google Play Store, you will need to create a new listing for the app under the new package name. This means that you will have to upload a new APK file with the updated package name, and users who have previously installed the app will need to download the update. It’s also important to note that changing the package name will result in a new app listing, which means that users will not be able to transfer their previous ratings or reviews to the new listing. Additionally, you will lose any downloads, reviews and ratings from your previous listing.

Change Package Name Android Apk

To change the package name of an Android APK, you will need to follow these steps:

1. Open the Android project in Android Studio.
2. In the Project pane, right-click on the package name and select Refactor > Rename.
3. In the pop-up dialog, enter the new package name and click Refactor.
4. Android Studio will automatically update all references to the old package name with the new one.
5. Finally, you will need to rebuild the APK and sign it with a new keystore before publishing it to the app store.

Note: Changing the package name will also change the application ID, which is used by the Android operating system to identify your app. This means that the new package name will have to be unique and cannot be the same as any existing app in the Google Play store.

Android Change Package Name Dynamically

It is not possible to change the package name of an Android app dynamically at runtime. The package name is hard-coded into the app’s APK file and is used by the Android operating system to identify the app. Changing the package name would require modifying the APK file and re-signing it with a new keystore, which is not possible while the app is running.

However, you can use different build variants and flavors in android studio to have multiple package names for different builds.

You can also use a different package name for different versions of your app by using the applicationIdSuffix in your build.gradle file. This will append a string to the end of the package name, allowing you to have multiple versions of your app with different package names on the same device.

Additionally, you can use the android:sharedUserId attribute in your app’s AndroidManifest.xml file to share a single user ID and data directory among multiple apps. This allows multiple apps to share the same package name and data storage, but still be treated as separate apps by the Android operating system.

How to change the name of apk file in Android Studio?

In Android Studio, you can change the name of an APK file by editing the applicationId attribute in the build.gradle file for your app module.

1. Open the build.gradle file for your app module.
2. Find the defaultConfig block and within that, the applicationId attribute.
3. Change the value of applicationId to the desired package name.

Be aware that changing the package name can cause issues if you have already published the app to the Play Store or if you have hard-coded the package name in your code. You may need to update your code or the Play Store listing to reflect the new package name.

What is package name in Android Studio?

In Android Studio, a package name is a unique identifier for an Android app. It is typically in the format of “com.example.appname”, where “com” is the top-level domain, “example” is the domain of the organization or developer, and “appname” is the name of the app.

The package name is used to uniquely identify an app on the device, in the Google Play Store, and in various other places where apps are distributed or referenced. It is also used as the base for the default Java package for the app’s source code.

When you create a new project in Android Studio, it will automatically generate a package name for you based on the name of the project. You can edit the package name in the build.gradle file by editing the applicationId attribute under defaultConfig.

It’s important to note that once you have published an app with a certain package name to the Play Store, you should not change the package name, as it will be treated as a new app and will not receive updates from the previous version.

FAQs – How to Change Package Name & App Name of Android Application in Android Studio

Q1. How do I edit a package?

To edit a package, you will need to access the source code of the package and make the necessary changes. You can do this by downloading the package’s source code from a version control system such as GitHub, or by using a package manager like pip to install the package in editable mode. Once you have the source code, you can use a text editor or integrated development environment (IDE) to make your changes. After making the changes, you will need to rebuild and re-install the package for the changes to take effect. Depending on the package and your system, you may also need to use specific commands or tools to rebuild and re-install the package.

Q2. How to find package name in Android Studio?

In Android Studio, you can find the package name of your project by looking at the package declaration in the file AndroidManifest.xml. The package name is specified in the package attribute of the manifest element. This file is usually located in the app/src/main directory of your project.

You can also locate the package name by going to the Project pane on the left side of the screen, expanding the app folder, and then expanding the java folder. The package name is the name of the folder that contains your MainActivity.java file.

Another way to find package name is by right-clicking on the project in the project window and selecting Open Module Settings and then check the package name on the right side of the window under Flavor tab.

You should keep in mind that the package name should be unique across all apps on the Play Store and should follow Java’s package naming conventions.
