What approach would you recommend for performing tasks asynchronously in the background?

To perform tasks asynchronously in the background on Android, the following approaches are often used:

• WorkManager — the recommended method for deferred and guaranteed tasks that should execute even if the app is closed or the device is restarted.
• Coroutines (Kotlin) — a convenient way to write asynchronous code, especially for short background operations.
• HandlerThread and ThreadPoolExecutor — for managing threads manually if lower-level customization is needed.

Example of using WorkManager:

class MyWorker(context: Context, params: WorkerParameters) : Worker(context, params) {
    override fun doWork(): Result {
        // Execute background task
        return Result.success()
    }
}

// Starting the task
val workRequest = OneTimeWorkRequestBuilder<MyWorker>().build()
WorkManager.getInstance(context).enqueue(workRequest)

WorkManager ensures reliable execution of tasks considering constraints (e.g., battery charge, network).
