What libraries or tools for thread management do you know and have used in your projects?

In Android, the following tools are often used for managing threads and asynchronous tasks:

• Thread — a basic class for creating and managing threads.
• Handler and Looper — for message processing and executing code on the main (UI) thread.
• AsyncTask (deprecated, but still encountered) — simplified background task execution with UI updates.
• Executor and ThreadPoolExecutor — for managing thread pools and executing tasks.
• RxJava — a library for reactive programming, simplifies working with asynchronous data streams.
• Kotlin Coroutines — a modern and convenient way to write asynchronous code, integrates with Android.

For example, with Kotlin Coroutines, you can easily perform network requests in a background thread and update the UI after completion:

GlobalScope.launch(Dispatchers.Main) {
    val data = withContext(Dispatchers.IO) { fetchData() }
    updateUI(data)
}
