What methods are used to perform background task execution in Android applications?

In Android, there are several approaches to perform background tasks, depending on the requirements of the task and the OS version:

1. AsyncTask (deprecated, not recommended for new projects) — a simple way to perform a task in the background with UI updates.

2. HandlerThread and Handler — for creating a background thread with a message queue.

3. ExecutorService — a standard Java thread pool for managing tasks.

4. WorkManager — the recommended way for deferred and guaranteed tasks, especially if you need to consider constraints (e.g., battery charge, network). Works on all Android versions.

5. JobScheduler — for scheduling tasks starting from Android 5.0 (API 21), allowing tasks to be executed considering conditions (charge, network).

6. Foreground Service — for long-running tasks that should continue even when the app is minimized, with a notification in the status bar.

Example of using WorkManager:

val workRequest = OneTimeWorkRequestBuilder<MyWorker>().build()
WorkManager.getInstance(context).enqueue(workRequest)

Where MyWorker is a class inheriting from Worker, implementing the background task logic.
