     * with the {@link #createPreviewAllocation createPreviewAllocation }

     * set by {@link #setPreviewCallback setPreviewCallback} or
     * {@link #setPreviewCallbackWithBuffer setPreviewCallbackWithBuffer}, and
     * vice versa. Using a preview allocation still requires an active standard
     * preview target to be set, either with
     * {@link #setPreviewTexture setPreviewTexture} or
     * {@link #setPreviewDisplay setPreviewDisplay}.</p>
     *
     * <p>To be notified when new frames are available to the Allocation, use
     * {@link android.renderscript.Allocation#setIoInputNotificationHandler Allocation.setIoInputNotificationHandler}. To
     * update the frame currently accessible from the Allocation to the latest
     * preview frame, call
     * {@link android.renderscript.Allocation#ioReceive Allocation.ioReceive}.</p>
     *
     * <p>To disable preview into the Allocation, call this method with a
     * {@code null} parameter.</p>
     *
     * <p>Once a preview allocation is set, the preview size set by
     * {@link Parameters#setPreviewSize setPreviewSize} cannot be changed. If
     * you wish to change the preview size, first remove the preview allocation
     * by calling {@code setPreviewCallbackAllocation(null)}, then change the
     * preview size, create a new preview Allocation with
     * {@link #createPreviewAllocation createPreviewAllocation}, and set it as
     * the new preview callback allocation target.</p>
     *
     * <p>If you are using the preview data to create video or still images,
     * strongly consider using {@link android.media.MediaActionSound} to
     * properly indicate image capture or recording start/stop to the user.</p>

     * @throws IOException if configuring the camera to use the Allocation for
