3.问题描述：
升级到Beta5版本，身份证拍摄页面，调用卡证识别控件，身份证正面拍摄可以获取到照片，国徽面获取不到照片，Beta2版本正常，报13900002 No such file or directory 错误
解决方案：
在IDE右下角的Device File Browser进入手机目录结构，看一下图片是否存在。
或者在工程中用 fs.access 判断一下文件是否存在b65K9s2c8@1M7s2y4Q4x3@1q4Q4x3V1k6Q4x3V1k6V1k6i4k6W2L8r3!0H3k6i4u0Q4x3X3g2Z5N6h3q4%4k6h3W2Q4x3X3g2U0L8$3#2Q4x3V1k6U0L8$3&6K6N6h3#2W2M7W2)9J5c8X3y4F1i4K6u0r3k6r3!0U0i4K6u0r3K9r3q4J5L8h3!0F1P5h3!0K6i4K6u0V1M7X3g2X3k6i4u0W2L8X3y4W2M7#2)9J5k6q4j5#2i4K6u0r3K9Y4y4Q4x3X3c8S2M7r3W2K6i4K6u0V1k6X3W2D9k6g2)9J5k6r3k6K6i4K6u0V1g2U0g2Q4x3U0y4X3M7$3q4U0j5$3g2K6M7H3`.`.
CardSide说明：
FRONT 0 身份证人像面或其他卡证正面。
BACK 1 身份证国徽面或其他卡证反面。
DEFAULT 2 卡证默认面。如身份证为人像面和国徽面，护照为单面。

活体检测有没有安全性报告？用到交易开户场景是否涉及合规问题？
解决方案：
1-2周内会有CFCA认证报告，合规和安全问题需要伙伴结合自己的使用场景综合评估
