如何使用Invoke传递接口回调参数

想要使用Nativey调用原生拍照对像内的拍照。原生代码片段如下：

    camera.takePicture(null, null, picture);

对于picture，定义如下：

private Camera.PictureCallback picture = new Camera.PictureCallback() {  

        @Override  
        public void onPictureTaken(byte[] data, Camera camera) {  
            ByteArrayInputStream bais = new ByteArrayInputStream(data);  
            Drawable d = BitmapDrawable.createFromStream(bais, Environment  
                    .getExternalStorageDirectory().getAbsolutePath()  
                    + "/img.jpeg");  

            try {  
                File dir = new File(Environment.getExternalStorageDirectory()  
                        .toString() + "/Villean/");  
                if (!dir.exists()) {  
                    dir.mkdirs();  
                }  
                String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmms",  
                        Locale.CHINA).format(new Date());  
                File file = new File(dir.getPath() + "/" + timeStamp  
                        + "TouPai.jpg");  
                FileOutputStream outStream = new FileOutputStream(file);  
                outStream.write(data);  
                outStream.close();  
                control = true;  
                camera.startPreview();  
            } catch (FileNotFoundException e) {  
                // TODO Auto-generated catch block  
                e.printStackTrace();  
            } catch (IOException e) {  
                // TODO Auto-generated catch block  
                e.printStackTrace();  
            }  
            l.setBackgroundDrawable(d);  
        }  
    };

以上为android原生代码。

现在想要使用Navite实现，代码如下：

function androidAutoCamera() {  

    // Android平台导入Camera类  
    var Camera = plus.android.importClass("android.hardware.Camera");  
    // 创建Camera的实例对象  
    var camera = Camera.open(0);  
    //camera.setDisplayOrientation(90);  

    var pickCallBack = plus.android.implements("android.hardware.Camera.PictureCallback", {  
        "onPictureTaken": function(data,tcamera) {  
            alert('1');  
        }  
    });  
    alert('piccallback:'+pickCallBack);  

    plus.android.invoke(camera, "takePicture",null, null,pickCallBack);  

    alert(camera);  
}  

但是alert('1')的代码并未能触发，还请帮忙看看这样的方式调用回调是不是不正确的。在示例代码中并未查到这种复杂调用的参数的示例 。
