getSize always return zero
<p>I am trying to capture the area of the finger touching the screen and also the amount of pressure over the screen. I have tried <code>Motionevent.getsize()</code> and I always get a value of 0. Also, <code>Motionevent.getpressure()</code> always gives me a value of 1.</p>

<p>Other functions like getX(), getY(), and getEventTime() seem to work fine.  Is there another way to get the size and pressure of the touch event?</p>
