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:
