Change Application Package Name Through Android Studio

I am aware that this question is asked several times in SO. I have checked below answers posted but doesn't work for me :( Solution 1 Solution 2 Currently, my application's packa

Solution 1:

The packageName attribute is deprecated as of Android Studio V0.0.6 onward. To change the package name of the application, use applicationId instead. Check the release notes here.

Change the applicationId and sync gradle.

Solution 2:

If your aim is to have the same application at two instance in the device, it is so easy to do using gradle. You don't need to change package name in the Manifest file, gradle will handle that during the build process for you and do all package renaming under the hood wherever required.

In order to achieve that you need to write a new product flavor for your app inside the main app module's build.gradle file with a different application id(package name). Eg. if com.example.test is your default package name of the app. You can have a different flavor of the same app with a different package name or knows as application id. produltFlavours can be defined inside android tag of your main module's build.gradle file like as shows below.

productFlavors {
    app1 {
        applicationId "com.example.test.test1"
    }
}

Sync your project after making the changes. Now select the build variant from Build Variant tab in left hand panel and hit run. Gradle script will handle all package renaming for you.
