Hi All,
I have a requirement to Capture the image without showing the Preview.. And i want to do it in the Background as a Service.
Is it possible to do that??
Thanks for the information.. May i know the reason why is it not possible?? Actually the camera preview and capture are independent tasks right???

@uday: "May i know the reason why is it not possible?" -- because Google said so. "Actually the camera preview and capture are independent tasks right?" -- no, they are not. You must show the preview in order to perform an image capture, which means these tasks are not independent.

I think the problem is while doing setParamaerts() method..
