• Android applications are made up of different components that work together to create a complete user interface.
• Two of the most important components in Android development are activities and fragments.
• An activity represents a single screen in an application. It can be considered as a window where the user interacts with the application.
• Activities are responsible for managing the lifecycle of the application and for handling user input events. An application can have multiple activities that can interact with each other.
• On the other hand, a fragment is a modular section of an activity. It is a reusable piece of user interface that can be added or removed from an activity.
• A fragment can be considered as a sub-activity that can be used to build a multi-pane user interface. Fragments have their own lifecycle and can be added or removed from an activity while the activity is running.
• The main difference between activities and fragments is that an activity is a complete, self-contained screen while a fragment is a modular unit that can be combined with other fragments to create a complete screen.
• Activities are used to manage the overall navigation of an application, while fragments are used to create more complex user interfaces.
• In summary, activities and fragments are both important components in Android development.
• Activities represent complete screens in an application, while fragments are modular units that can be combined to create more complex user interfaces.
• Understanding the differences between these two components is crucial for developing robust Android applications.
