Part1 Android fundamental questions like

1. What are the key differences between Service and IntentService in Android? In which scenarios would you use each one?

2. If a previously recommended background processing component is no longer supported, what is the current best practice for handling long-running tasks in the background?

3. Which UI component is typically used for efficiently displaying large collections of items in a scrollable list?

4. How does the pattern for efficiently managing and binding views in a list component work? How would you adapt this pattern to display items horizontally or in a grid layout?

5. What is the concept of deep linking, and how does it enable opening specific screens in an app from a URL?

6. When using code shrinking or obfuscation tools, why might you encounter runtime errors related to missing classes, especially when using reflection, and how can these issues be addressed?

Part2 Debugging/ fix

Code was related to using a BroadcastReceiver to listen for airplane mode changes.

Part 3 Improve performance

Code was related to

"How would you design and implement a background task in Android using WorkManager to save a Student object (with ID and name) to SharedPreferences, synchronize it with a remote source, and also persist it using a DAO (database)? Please demonstrate how you would structure your Worker class, use a singleton for the database, and leverage coroutines (including suspend functions and coroutine scope) to handle asynchronous operations. Show how you would report success or failure from the Worker.

Part 4 Code

You are given a list of strings, each representing an item that has been selected or used. Write a function that determines which item appears most frequently in the list, along with the total number of times it appears. If there is a tie, return the item that occurs first in the list. The comparison should be case-insensitive, but the output should preserve the original casing of the earliest occurrence.

From memomry. Hope it helps.
