  1. What is LiveData in Android Jetpack?

    Answer: An observable data holder that respects the lifecycle of app components

    LiveData is a lifecycle-aware observable data holder that automatically updates UI observers only when they are in an active lifecycle state.

  2. What is the primary purpose of the Application class in Android?

    Answer: To maintain global application state for the app's lifetime

    The Application class is instantiated before any Activity and is used to maintain global application state and initialize app-wide singletons.

  3. What distinguishes a bound Service from a started Service in Android?

    Answer: A bound Service allows components to bind to it and interact via a client-server interface

    A bound Service offers a client-server interface that allows components to bind, send requests, and receive results, and it runs only as long as a component is bound to it.

  4. What is the Jetpack Navigation Component primarily used for?

    Answer: Handling in-app navigation between destinations

    The Jetpack Navigation Component simplifies implementing navigation between fragments and activities using a visual navigation graph.

  5. In the Activity lifecycle, what state is the Activity in immediately after onResume() is called?

    Answer: Running/Resumed

    After onResume() is called, the Activity is in the Running (Resumed) state — it is in the foreground, visible, and actively interacting with the user.

  6. What is the role of a ContentProvider's URI in Android?

    Answer: It uniquely identifies a dataset exposed by the ContentProvider for access

    A ContentProvider URI uniquely identifies the provider and the specific data table or record to access, following the format content://authority/path/id.
