android - Camera.setPreviewCallback( PreviewCallback ) not working -

i'm trying photographic camera preview data, don't want show preview. unfortunatelly

setpreviewcallback( previewcallback )

doesn't work unless call

setpreviewdisplay(surfaceholder)

is possible pass in way - start callbacks without setting preview display, or way of hiding display?

well, it's not ideal solution, can seek hiding view in. made have width , height of 1, barely visible, still valid surfaceholder phone call need make.
