title: Long click confirmation (vibration)
body: <p>In my app, some views react to <code>onLongClick</code>.  In others, I want to achieve the same functionality, but I want to know which part of the view was long-clicked -- so I'm simulating it with <code>onTouchEvent</code>.  The default device behavior on the long click is vibration.  I would like to do the same on a <i>simulated</i> long click.</p>
  
  <p>I know how to get permission for the vibrator and do whatever I want with it.  Is that the only way?  I'm looking for a function that does a "default" vibrate, like <code>playSoundEffect</code> plays a handful of default system sounds.  Basically, all I want to do is perform a default system reaction to a long click.  It may not even be vibration on some devices...</p>
