代码：

        mCameraHelper = new CameraHelper();
        mCameraHelper.setStateCallback(new ICameraHelper.StateCallback() {
            @Override
            public void onAttach(UsbDevice device) {
                if(isSupportedDevice(device)) {
                    mCameraHelper.selectDevice(device);
                }
            }

            @Override
            public void onDeviceOpen(UsbDevice device, boolean isFirstOpen) {
                if(isSupportedDevice(device)) {
                    mCameraHelper.openCamera(new Size(DEFAULT_PREVIEW_FRAME_FORMAT, 2448,3264, DEFAULT_PREVIEW_FPS, new ArrayList<>(DEFAULT_PREVIEW_FPS))); // this occur error
                }
            }

           ...
        });
