Hello every one.
Welcome back.
So far during this section, you learnt about some basics of Android Navigation Component Framework.
You learnt about navigation graph, navigation host fragment, destinations, actions and arguments. I have a small exercise for you. I want you to add another fragment as a navigation destination.
On the second fragment, you should add a button and write codes to open the third fragment using an action. Then on the third fragment, I want you to add another button and write codes to navigate back to the Main Fragment.
