ey Responsibilities:

1. Data Retrieval:
   • Fetches user profile details from the backend API using network requests.
   • Handles potential errors such as network timeouts or invalid responses.
2. Data Caching:
   • Stores retrieved user data locally using shared preferences or a database (e.g., Room).
   • Provides offline access to cached user profiles when network connectivity is unavailable.
3. Data Synchronization:
   • Synchronizes local user data with the remote server to ensure consistency.
   • Updates the backend with any changes made to the user profile within the app.
4. Access Control:
   • Provides methods to securely access user data, ensuring that sensitive information is protected.

Example Methods:

1. fetchUserProfile(userId: String): LiveData<User>
   Retrieves the user profile from the server and updates the local cache.
2. getCachedUserProfile(): User?
   Returns the locally cached user profile or null if no data is available.
3. updateUserProfile(updatedProfile: User): Boolean
   Sends updated profile details to the server and refreshes the local cache upon success.
4. clearCachedProfile()
   Deletes the cached user profile data, typically used during logout operations.

Usage Example:

Design Considerations:

• Implements Singleton Pattern to ensure only one instance of the class is used throughout the application.
• Integrates with dependency injection frameworks (e.g., Hilt or Dagger) for seamless lifecycle management.
