What advantages and disadvantages arise when using a large number of Activities in an application?

Using a large number of Activities in an Android application has its pros and cons.

Advantages:

• Clear separation of logic and UI between screens.
• Simplified navigation, as each Activity is responsible for a separate screen.

Disadvantages:

• Increased memory consumption, as each Activity consumes resources.
• Complication of managing the lifecycle and navigation between many Activities.
• Possible performance issues when frequently creating and destroying Activities.

Modern applications often use a single Activity with multiple Fragments to optimize resources and enable more flexible navigation.
