Hello every one.
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.
