In android studio, in design section, Layouts and Containers are categorized separately.
What is the fundamental difference between them?
Layouts are general-purpose ViewGroups dealing directly with graphical views. They have no requirements on what kind of children they can manage. Containers fulfill more specific tasks, that's why they have additional requirements on how many and which kind of children they can accept.
A layout defines the structure for a user interface in your app, such as in an activity. All elements in the layout are built using a hierarchy of View and ViewGroup objects. A View usually draws something the user can see and interact with.
Android Layout is used to define the user interface that holds the UI controls or widgets that will appear on the screen of an android application or activity screen. Generally, every application is a combination of View and ViewGroup.
To make an APK file, a program for Android is first compiled using a tool such as Android Studio or Visual Studio and then all of its parts are packaged into one container file. An APK file contains all of a program's code (such as .dex files), resources, assets, certificates, and manifest file.
I would define the differences as follows:
