how to avoide duplication of threads?
<p>I am newly joined android family.</p>

<p>I am implementing one thing related to handlers and threads.</p>

<p>When i am running my application one handler is created and run.</p>

<p>it is fine,but i am run my application another time,again
one more handler is created and run.</p>

<p>It increases duplication of handlers - how can I avoid this?</p>
