How to run task using Thread in Background

I wanted to do some task in the background like in android we can use AsyncTask to do some work using UI thread, in Harmony we have EventHandler which allows us to send and process InnerEvent and Runnable objects on asynchronous threads.

I just want a simple example on how to use it.

please check the sample -

 public class EventHandlerImplementation extends EventHandler {
        private EventHandlerImplementation(EventRunner runner) {
            super(runner);
        }

        @Override
        public void processEvent(InnerEvent event) {
            getUITaskDispatcher().asyncDispatch(() -> {
                 // do your stuff here
            });
        }
    }
