android publish/subscribe pattern
<p>Is there a publish/subscribe pattern in android? </p>

<p>What I want to achieve is I have this class that can notify interested party of an event. Then the interested party can do whatever it needs. </p>

<p>Coming from a .net microsoft world, this sort of thing are build in. </p>

<p>Do android have something similar, or I have to write some thing like an observer pattern?</p>
