android show rectangle on camera

Hi I want to show a rectangle in camera so that when the user takes snap only the region inside the rectangle can be processed. Any idea how can I do it? And the rectangle size can be resized by dragging along the corners.

I am not calling the camera application. I am using the camera API.

I think you need to draw a rectangle that has size as you desire. Then you just need to set that size for preview frame, and when you get the result return from onPreviewFrame , you will process on that data. You can refer the ViewfinderView class of Xzing source here to learn how to draw a rectangle in camera preview. and refer CameraConfigurationManager,PreviewCallback,CameraManager also in xzing source to learn how to set preview size and process result data return from camera driver. Hope this help you.
