Sure! In Android development, the main differences between Activities and Fragments lie in their lifecycle management and reusability.

Activities:
- The focus keyword here is "Activities."
- Activities represent single, focused tasks that users can interact with.
- Each screen in an Android app is typically represented by an Activity.
- Activities have their own lifecycle methods such as onCreate, onStart, onResume, onPause, onStop, and onDestroy.
- Activities are heavier than Fragments in terms of memory consumption.

Fragments:
- The focus keyword here is "Fragments."
- Fragments are modular components that represent a portion of the user interface.
- Fragments can be used within Activities to build a multi-pane user interface or to facilitate reusability across different screens.
- Fragments have their own lifecycle methods, similar to Activities, but they are more flexible in terms of lifecycle management.
- Fragments are lighter than Activities and can be easily added or removed from an Activity dynamically.

In summary, Activities represent entire screens in an Android app and have their own lifecycle, while Fragments are modular components that can be used within Activities to create a more dynamic and flexible user interface. It's important to choose between Activities and Fragments based on the specific needs of your app to optimize performance and user experience.
