Get pixel value from an Android display?
<p>I'm not even concerned with the camera per se.  I want at the closest thing to the display screen.  Meaning:  it could even be the desktop the user is looking at, completw w/ the background and the icons she moves back and forth.  </p>

<p>Let's say, at time t=1 sec, the app goes to pixel (78, 300) on that display and obtains its value.  What may be at (78, 300) could be a portion of the icon or some speck of tree leaf on the photo being used as desktop background.</p>

<p>I'm familiar with BitmapFactory.decodeFile() for getting at the pixel contents of a file.  But what about the display?</p>

<p>Thank you for any assistance.</p>
