/**
Open Declaration String android.provider.MediaStore.ACTION_IMAGE_CAPTURE = "android.media.action.IMAGE_CAPTURE"
Standard Intent action that can be sent to have the camera application capture an image and return it.
The caller may pass an extra EXTRA_OUTPUT to control where this image will be written. If the EXTRA_OUTPUT is not present, then a small sized image is returned as a Bitmap object in the extra field. This is useful for applications that only need a small image. If the EXTRA_OUTPUT is present, then the full-sized image will be written to the Uri value of EXTRA_OUTPUT. As of android.os.Build.VERSION_CODES.LOLLIPOP, this uri can also be supplied through android.content.Intent.setClipData(ClipData). If using this approach, you still must supply the uri through the EXTRA_OUTPUT field for compatibility with old applications. If you don't set a ClipData, it will be copied there for you when calling Context.startActivity(Intent).
See Also:EXTRA_OUTPUT
标准意图，被发送到相机应用程序捕获一个图像，并返回它。通过一个额外的extra_output控制这个图像将被写入。如果extra_output是不存在的，
那么一个小尺寸的图像作为位图对象返回。如果extra_output是存在的，那么全尺寸的图像将被写入extra_output URI值。
