What can I use instead of IntentService?

This class was deprecated in API level 30. IntentService is subject to all the background execution limits imposed with Android 8.0 (API level 26). Consider using WorkManager or JobIntentService , which uses jobs instead of services when running on Android 8.0 or higher.

Intent Services are also designed specifically to handle background (usually long-running) tasks and the onHandleIntent method is already invoked on a background thread for you. An AsyncTask is a class that, as its name implies, executes a task asynchronously.

How does asynctask work on a worker thread?

AsyncTask allows you to perform asynchronous work on your user interface. It performs the blocking operations in a worker thread and then publishes the results on the UI thread, without requiring you to handle threads and/or handlers yourself.

What’s the difference between a service and an intentservice?

IntentService is a base class for Services that handle asynchronous requests (expressed as Intents) on demand. Clients send requests through startService (Intent) calls; the service is started as needed, handles each Intent in turn using a worker thread, and stops itself when it runs out of work.
