        You can do it with a buildType. Something like:
buildTypes {
        debug {
            applicationIdSuffix ".debug"
        }
}
Or you can do it with a flavor
 productFlavors {
        f1 {
            applicationId = "com.example.my.pkg.f1"
        }
        f2 {
            applicationId = "com.example.my.pkg.f2"
        }
}

according to this link
- copy your project to another directory and rename folder
 - open it in android studio
 - right click on package name and refactor -> rename
 - (optional) change app name in res-> values and in build.gradle -> defaultConfig -> applicationId
