What's the best way to handle network requests in a background thread on Android?
Asked on Feb 10, 2026
Answer
Handling network requests in a background thread on Android is crucial for maintaining a responsive UI. The recommended approach is to use Kotlin Coroutines or Java's ExecutorService to perform network operations off the main thread, ensuring smooth user interactions.
Example Concept: Use Kotlin Coroutines with Retrofit for efficient network requests on Android. By launching a coroutine in a background dispatcher (e.g., Dispatchers.IO), you can perform network operations asynchronously. Retrofit's suspend functions integrate seamlessly with coroutines, allowing you to handle responses and errors in a structured way, while keeping the UI thread free for rendering and user input.
Additional Comment:
- Use Retrofit with a Coroutine Call Adapter for seamless coroutine integration.
- Ensure proper error handling using try-catch blocks or Kotlin's Result class.
- Consider using LiveData or StateFlow to observe network results in the UI layer.
- Always test network operations under various conditions (e.g., slow network, no connection).
- Profile network requests to optimize performance and reduce latency.
