title: Android: Listener to record sound if any sound occurs
body: <p>In my application I want to implement methods which record the sound if any sound occurs.</p>
  
  <p>Something similar like this app: <a href="https://market.android.com/details?id=com.outfit7.talkingtom&amp;feature=search_result" rel="noreferrer">Talking Tom Cat</a></p>
  
  <p>So what should I have to do?
  Is there any demo that listens for sound and records it if any sound occurs?</p>
