/**
* Flash will be fired automatically when required. The flash may be fired
* during preview, auto-focus, or snapshot depending on the driver.
*/
public static final String FLASH_MODE_AUTO = "auto";
/**
* Flash will always be fired during snapshot. The flash may also be
* fired during preview or auto-focus depending on the driver.
*/

/**

*/
public static final String FLASH_MODE_RED_EYE = "red-eye";
/**
* Constant emission of light during preview, auto-focus and snapshot.
* This can also be used for video recording.
*/
public static final String FLASH_MODE_TORCH = "torch";點亮閃光燈:FLASH_MODE_TORCH
關閉閃光燈:FLASH_MODE_OFF
這個兩個參數，足夠實現手電筒的功能。
FLASH_MODE_ON 只有在 takePicture(ShutterCallback shutter, PictureCallback raw, PictureCallback jpeg) 時，纔會點亮閃光燈。
