How can a system of navigation between different sections or pages of the application be organized?

In Android, to organize navigation between different sections or pages of an app, Intent and Activity are commonly used. The main method is to start a new Activity via Intent:

val intent = Intent(this, TargetActivity::class.java)
startActivity(intent)

You can also use Fragments for navigation within a single Activity, switching different fragments in a container. To simplify navigation, the Navigation Component library is often used, which allows describing navigation as a graph and managing transitions centrally.

Thus, the main methods are:

• Launching new Activities via Intent
• Using fragments and FragmentManager
• Navigation Component for declarative navigation management

The choice depends on the app's architecture and navigation requirements.
