I am confused on how to implement image processing algorithm on JPEG
data.I have set P.setpicturesize (640,480) so the  camera.takepicture
(null,null,Imagecapture callbck) returns the image data.

Void onPictureTaken(byte[] data, Camera Camera) returns JPEG data,
but     ------->(x = data.length) , the value of x is less than
640*480 bytes.Please kindly let me know how can I start editing pixel
information of the image and image comparison algorithms.

thank you,

2. Fill-remainder layout?

I'm used to Java Swing layout managers (especially GridBagLayout), and I
haven't been able to figure out to do something relatively simple with the
Android layouts.

I want to have a bar of controls at the top, and another bar of controls at
the bottom.
Then I want to have an area in the middle that uses whatever space is left
over.  (mainly for graphics drawing)
I'm currently using a RelativeLayout with 2 Linear layouts for the top and
I just haven't been able to find a combination of layouts that lets me have
a view just fill the middle remainder area.
I'm trying to start with a simple background color on a view in this area.
if I use "wrap_content" it's way too small.
If I use "fill_parent" it fills the ENTIRE parent, including the areas used
by the 2 bars of controls.

How do I define something to just fill the remaining space in the middle?
