Compose Navigation Quiz

Welcome to the quiz on Navigation in Compose! This quiz will test your understanding of key concepts such as navigation controllers, navigation graphs, routes, passing arguments, and managing the navigation back stack in Android apps using Jetpack Compose. Each question will challenge your knowledge of implementing smooth and efficient navigation flows.

How can you pass arguments between destinations in Compose navigation?

To refresh the entire navigation stack.

To animate bottom bar transitions.

To fetch data from a remote server.

To determine the currently selected navigation item.

None

What is the purpose of using routes in a navigation graph?

To style the UI components of the app.

To define the data schema of a database.

None

How is a navigation graph defined in Compose?

By using the NavHost and specifying destinations within it.

None

10.

Which method is used to get the current back stack entry in Compose?

currentBackStack()

currentBackStackEntryAsState()

navController.getCurrentEntry()

None

11.

What is the primary role of the NavHostController?

To store user data securely.

To manage navigation actions and the back stack.

To render the UI components of the app.

To perform background data synchronization.

None

12.

What is the purpose of saveState and restoreState options in navigation?

None

14.

What is the main benefit of using the launchSingleTop parameter in navigation?

It launches multiple instances of the destination at the top.

It ensures only a single instance of a destination is created at the top of the stack.

It triggers animations between transitions.

It resets the entire back stack before navigating.

None

15.

What is a destination in the context of Compose navigation?

A service that runs in the background of an Android app.

A UI component that manages user input.

A screen or composable that a user navigates to within the app.

A function that initializes the navigation controller.

None

16.

How can you avoid pushing multiple instances of the same destination onto the back stack?

Create a new instance of NavHostController each time.

Disable recomposition in the destination composable.

Set launchSingleTop to true in the navigate() method.

Use the replaceTop() method of the navigation controller.

None

None

20.

The type of arguments passed between destinations.

The theme to be applied to the NavHost.

The size of the navigation back stack.

None
