+## 4. 编译Android工程生成apk即可
+如果对assets中的内容做改动，需要先卸载已经安装的vnn的apk, 再重新安装(因为demo未对assets内容二进制校验，只校验了文件夹, 新添加的文件夹会自动拷贝到手机上)  
+## 5. 其它
+### (1) 横竖屏问题：Demo目前只支持竖屏显示效果，横屏未对结果做相应的渲染适配。
+### (2) 涉及到多个人脸的，与分割有关的，如头部分割，3d game风格等，会产生多个mask。 demo只是简单的将所有的mask画到同一张图上，再做后续处理，因为mask的重叠问题，可能会引起效果上的显示问题，实际使用时应该每个mask都单独做后续处理。
