title: Can the Android handset LED be manipulated without using a Notification object?
body: <p>I want to control the LED on an Android device with more control than is offered by the Notification class.  Notifications allow you to change the rate of flashing; e.g. 300 milliseconds on, 1000 milliseconds off, but that's it.</p>
  
  <p>Essentially, I would like to turn the LED on and off at will at arbitrary times. Does anyone know if this is possible? The API does not seem to say so. Does it depend on the specific hardware?  </p>
