Android Studio: Rename Package (Application Id)

Usually, you just need rename Application Id in module:app build.gradle file.

• By default, the applicationId exactly matches the Java-style package name
• The applicationId and package name are independent of each other (both does not need to be the same)
• applicationId is used to identify your app in play store (e.g. https://play.google.com/store/apps/details?id=com.luasoftware.luapass)
• applicationId is used to identify your app in Android OS. You can rename the applicationId and compile another APK for installation, and Android OS shall treat it as a different application.
• Java-style package name only matter to you as a developer.

android {
    defaultConfig {
        applicationId "com.luasoftware.luapass"
        minSdkVersion 16
        targetSdkVersion 28
        multiDexEnabled true
        versionCode 2
        versionName "1.0.1"
    }
}
