Getting a non-stretched Camera Preview Screen

 Hi all,

I am trying to make an activity that (among other things) shows a
camera preview screen.  I have a translucent ImageView on top of the
camera preview, which is unstrechted.  The height is 295, so the width
should be ~400 pixels.  Unfortunately, no matter what I seem to do, I
cannot get the Preview I have (which is almost identical to the
apidemo camera preview View) to maintain a 4:3 view.  Instead, it is a
480x295 view, which produces undesirable horizontal stretches in the
preview.  None of my specifications of fixed sizes in the
SufraceHolder or the setPreviewSize() of the camera object make any
difference whatsoever.  I just want the camera preview to be 400x295,
with 40px margins on the left and the right of the screen so that it
is centered in teh same place as the image view.

Right now, I am stretching out the ImageView to the full screen so
they at least match, but ideally I would like to have vertical black
bars on the left and right edges of the screen to get more accurate
images.

1. CALL Activity to show application screen on call end

We are using CALL intent to place a call. However on call end, the
view is returning to Call Log Tab. Is there a way to tell the CALL
intent to finish the on call end.
