Key Points
- Android activities represent a single screen with a user interface (UI) of an application.
- Activities can start other activities to perform different actions based on requirements.
- Android activity lifecycle consists of various stages such as onCreate(), onStart(), onResume(), onPause(), onStop(), onRestart(), and onDestroy().
- Fragments in Android are modular sections of activity design used to represent the behavior of the UI.
- Fragments can be added or removed in an activity while it is running.
- Intents in Android are messaging objects used to request an action from other app components.
- Implicit intents do not specify the name of the component to be invoked and allow other apps to handle them.
- Explicit intents explicitly specify the name of the component to be invoked within the same app.

In Android, fragments can be inserted into an activity layout to modify the appearance of an app design at runtime. Fragments can be implemented without a user interface, improving the flexibility of the app UI and making it easier to adjust the design based on device
The excerpt discusses Android activities, fragments, and intents. It includes code snippets for a DetailsFragment class and a ListMenuFragment class. The DetailsFragment class is responsible for displaying the name and location of a user, while the ListMenuFragment class displays
When creating an intent in Android, it is important to specify both the URI and the MIME type of the data. This helps the Android system determine which component should receive the intent. The category of an intent is optional and provides additional information about the type
The text excerpt provides code snippets and explanations for implementing explicit intents in an Android application. It discusses the use of explicit intents to start a component within the app and send/share data between activities. The example includes two activities and two XML files.
