Camera Not saving the captured image

问题

I Use Qt 5.12.5 and I have qt quick controls 2 project that I run it on my Android Device.

Now I have a problem,the signal imageSaved of Camera Not trigger?

In below when I click button Camera should capture

Button{
    onClicked: {
        camera.imageCapture.capture();
    }
}

After Clicking the Button imageCaptured signal runs, the photoPrevew shows the captured image ,But onImageSaved Not running and I don't see any captured image in my Gallery!

Camera {
    id: camera
    position: Camera.BackFace
    imageProcessing.whiteBalanceMode: CameraImageProcessing.WhiteBalanceFlash

    flash.mode: Camera.FlashRedEyeReduction
    imageCapture {
        onImageCaptured: {                  ///this runs after capturing
            camera.stop();
            console.log("preview="+preview); ///  preview=image://camera/preview_1
            photoPreview.source = preview    ///photoPreview shows the capthed Image
            var imgPath = camera.imageCapture.capturedImagePath
            console.log("image Path=>"+imgPath); /// path is null
        }
        onCaptureFailed: {
            console.log("onCaptureFailed");
            console.log(message);
        }
        onImageSaved: {                             ///This not running
            console.log("*** onImageSaved ***");
            console.log("path=> "+path);
            up.loadImageFromFile("file://"+ path,imageOrientation);//this class upload Image to server
        }
    }
    focus {
        focusMode: Camera.FocusContinuous
        focusPointMode: Camera.FocusPointCenter
    }
}
