Do you apply the approach with a single activity in your project?

The Single Activity approach in Android assumes that the entire application consists of one Activity, and navigation and display of different screens are implemented through fragments.

Advantages:

• Centralized navigation management.
• Fewer issues with data transfer between screens.
• Simplified application state management.

However, this approach is not always suitable, especially for very simple applications or when screen isolation is required.

In my projects, I apply this approach when flexible navigation and scalability are needed, using the Navigation Component and ViewModel for state management.
