Write a class description

Price range: €16.23 through €21.21

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:

kotlin
val userProfileManager = UserProfileManager(context)
userProfileManager.fetchUserProfile("12345").observe(this, { profile ->
// Update UI with the fetched user profile
textViewName.text = profile.name
})

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.

Write a function description

Price range: €18.21 through €24.24

Description:
The fetchUserData() function is designed to asynchronously retrieve user-specific information from a designated remote server endpoint. It uses an HTTP GET request to access the resource and processes the response into a usable data structure, such as a JSON object. This function is typically utilized in applications requiring dynamic data loading for user profiles or account management.

Key Features:

  1. Asynchronous Operation: Implements suspend (Kotlin Coroutines) or async/await (JavaScript-style) to perform the request without blocking the main thread.
  2. Error Handling: Includes exception handling to manage network errors, timeouts, or invalid responses.
  3. Data Parsing: Converts the raw HTTP response into a structured format (e.g., a User model object) for seamless integration within the application.

Example Usage in Kotlin:

kotlin
suspend fun fetchUserData(userId: String): User {
val url = "https://api.example.com/user/$userId"
return withContext(Dispatchers.IO) {
try {
val response = HttpClient.get(url)
if (response.isSuccessful) {
return@withContext response.body<User>()
} else {
throw Exception("Error fetching user data: ${response.status}")
}
} catch (e: Exception) {
throw Exception("Network request failed: ${e.message}")
}
}
}
