What class does Android use to simplify background thread creation and UI thread synchronization?

Using BroadcastReceiver So you can use it to update the UI on the main thread. For example. Send data from a background thread. This method is usually used to communicate between Android apps or Android apps with the system.
Purpose of the Handler class. A Handler object registers itself with the thread in which it is created. It provides a channel to send data to this thread, for example the main thread. The data which can be posted via the Handler class can be an instance of the Message or the Runnable class.
To specify the thread on which to run the action, construct the Handler using a Looper for the thread. A Looper is an object that runs the message loop for an associated thread. Once you've created a Handler , you can then use the post(Runnable) method to run a block of code in the corresponding thread.
So in your Kotlin programs, performing heavy operations like network calls, interacting with Database/Device file system, etc, etc. You need to execute those tasks in the background thread. That's means you should consider using the Asynchronous approach.
AsyncTask is the class you are looking for.
You can find more information about it within the official Android Documentations.

AsyncTask
AsyncTask enables proper and easy use of the UI thread. This class allows to perform background operations and publish results on the UI thread without having to manipulate threads and/or handlers.
AsyncTask is designed to be a helper class around Thread and Handler and does not constitute a generic threading framework. AsyncTasks should ideally be used for short operations (a few seconds at the most.)
