Question

我创建了一个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，我尝试使用this method likn Android Studio实现库。

1。我有这个项目结构： Project Structure

2. 我从react-native教程

创建Native模块

3。当我跑步时： react-native run-android 我收到这些错误：

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

所以我的问题是：我是否遗漏了将OpenCV库包含在我的React-Native项目中的内容？

如何将OpenCV库添加到我的react-native项目中？
