已经购买，怎么使用扫描识别，老是报app identifier unmatch

        const BaiduOCRAndroidPlugin = uni.requireNativePlugin('lerchlee-baiduocrandroidplugin');  
        BaiduOCRAndroidPlugin.startRecognize("IDCardFront", res => {  
            uni.showModal({  
                title: '提示',  
                content: JSON.stringify(res),  
                success: function (res) {  
                    if (res.confirm) {  
                        console.log('用户点击确定');  
                    } else if (res.cancel) {  
                        console.log('用户点击取消');  
                    }  
                }  
            });  
        })
