What approaches exist for implementing background task execution in Android applications?

In Android, various approaches are used to perform background tasks depending on the timing requirements and conditions:

• AsyncTask (deprecated) — for simple short tasks executed in a background thread with UI updates.
• HandlerThread and Handlers — for managing a queue of tasks in a separate thread.
• Services — for long-running background operations that can work independently of the UI.
• IntentService (deprecated) — a service for sequential execution of tasks in the background.
• WorkManager — a modern API for deferred and guaranteed background tasks, considering battery limitations and device state.
• Thread and ExecutorService — for manual thread management.

Example of using WorkManager for a background task:

WorkRequest uploadWorkRequest = new OneTimeWorkRequest.Builder(UploadWorker.class)
    .build();
WorkManager.getInstance(context).enqueue(uploadWorkRequest);

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