Frames are the basic building blocks of Android apps. They provide a structure for your app’s UI and are also responsible for how your app behaves. There are different types of frames available that you can use to build your app.
Linear: This is the most common type of frame and is used in almost every single Android app. It provides an easy way to navigate through an app with a linear flow that starts at one point and ends at another point.
Relative: This type of frame is used when you have a complex layout where the location of each element changes depending on where it is placed in relation to other elements in the layout.
