How can a task be launched in a service so that it does not occupy the main execution thread?

In Android, to prevent a task from blocking the main (UI) thread, it needs to be run in a background thread. You can use:

• AsyncTask classes (deprecated but still used)
• Thread or Runnable
• HandlerThread
• ExecutorService
• Modern approach — use Kotlin Coroutines or WorkManager for background tasks

Example with Kotlin Coroutines:

GlobalScope.launch(Dispatchers.IO) {
    // Long operation, e.g., loading data
    val data = loadData()
    withContext(Dispatchers.Main) {
        // Update UI after completion
        updateUI(data)
    }
}

Thus, the main idea is to perform heavy operations outside the main thread so that the interface remains responsive.
