+ * handling/processing of the received frame data is always faster than
+ * the preview frame rate so that data corruption won't occur.

+ * 2. 0x01 enables a callback without copying out the received frames. A

+ * CameraHardwareInterface.h defines the interface to the
+ * camera hardware abstraction layer, used for setting and getting
+ * parameters, live previewing, and taking pictures.
+ *
+ * It is a referenced counted interface with RefBase as its base class.
+ * CameraService calls openCameraHardware() to retrieve a strong pointer to the
+ * instance of this interface and may be called multiple times. The
+ * following steps describe a typical sequence:
+ *
+ * -# After CameraService calls openCameraHardware(), getParameters() and
+ * setParameters() are used to initialize the camera instance.
+ * CameraService calls getPreviewHeap() to establish access to the
+ * preview heap so it can be registered with SurfaceFlinger for
+ * efficient display updating while in preview mode.
+ * -# startPreview() is called. The camera instance then periodically
+ * sends the message CAMERA_MSG_PREVIEW_FRAME (if enabled) each time
+ * a new preview frame is available. If data callback code needs to use
+ * this memory after returning, it must copy the data.
+ *
+ * Prior to taking a picture, CameraService calls autofocus(). When auto
+ * focusing has completed, the camera instance sends a CAMERA_MSG_FOCUS notification,
+ * which informs the application whether focusing was successful. The camera instance
+ * only sends this message once and it is up to the application to call autoFocus()
+ * again if refocusing is desired.
+ *
+ * CameraService calls takePicture() to request the camera instance take a
+ * picture. At this point, if a shutter, postview, raw, and/or compressed callback
+ * is desired, the corresponding message must be enabled. As with CAMERA_MSG_PREVIEW_FRAME,
+ * any memory provided in a data callback must be copied if it's needed after returning.
