Resolution for Preview and Capture with Android

as My Test, CameraBridgeViewBase supports up to 1920x1080 for preview.
but I want to do Image Processing with 4k(3840x2160) images.

Is it possible to set the Resolution of Preview to (3840x2160)?

Is it possible to get an image that has a higher resolution than the preview?
(preview is 1920x1080, get an Image that has 3840x2160 when I click a Button.)
