小编Vic*_*tor的帖子

我已经创建了一个react-native项目,我想做一些图像处理.我对OpenCV非常熟悉,所以我想在我的项目中使用OpenCV库.

我搜索了节点模块,但我找不到它.

所以,我尝试用这种方法实现库likn Android Studio.

1.我有项目的这种结构: 项目结构

2.我从react-native教程创建Native模块

本机模块项目结构

3.当我运行:react-native run-android我得到这些错误:

:app:compileDebugJavaWithJavac - is not incremental (e.g. outputs have changed, no previous execution, etc.).
