How do you implement asynchronous operation handling in your projects?

There are several approaches commonly used for handling asynchronous operations in Android projects:

1. Kotlin Coroutines — a modern and convenient way that allows writing asynchronous code in a sequential style. suspend functions and various dispatchers are used to manage threads.

import kotlinx.coroutines.*

fun fetchData() {
    GlobalScope.launch(Dispatchers.IO) {
        val data = fetchFromNetwork() // suspend function
        withContext(Dispatchers.Main) {
            updateUI(data)
        }
    }
}

2. Callbacks — a traditional method where the result of an asynchronous operation is passed through a callback interface.

3. RxJava — a library for reactive programming that makes it easy to work with data streams and asynchronous operations.

In modern projects, preference is given to coroutines due to their simplicity and integration with Kotlin.
