Accessing UI thread handler from a service

Question

I am trying some thing new on Android for which I need to access the handler of the UI thread.

I know the following:

1. The UI thread has its own handler

Answer 1

At the moment I prefer using event bus library such as Otto for this kind of problem. Just subscribe the desired components (activity):

protected void onResume() {
    super.onResume();
    bus.register(this);
}

Then provide a callback method:

public void onTimeLeftEvent(TimeLeftEvent ev) {
    // process event..
}

and then when your service execute a statement like this:

bus.post(new TimeLeftEvent(340));

That POJO will be passed to your above activity and all other subscribing components. Simple and elegant.
