Sparta Coding Club), Automatic handling of fragment transactions. You should see something like this: In this application, unlike the one we created with the Basic Activity template, there is no button to click to navigate to to the next destination.

These are the actions, which define the navigations that are possible in this graph. In this tutorial, we'll learn how to move fragments in Navigation Component. Since I am more interested in design through xml coding I will explain through codes. In addition, your app can run on the various versions because android Jetpack components run independently and providing backward compatibility. Based on the app requirements, we might use fragments in our app or we might not use and cover the most of the screens using Activity classes.
