如何在React Native CameraRoll Android版本上获得绝对图像路径？

Question

我知道当前版本不支持'绝对路径'，它只有'内容uri'，文件系统无法访问它。

我试图根据官方文档的源代码构建'React Native'。它仍然失败了。

1）第一个错误：

:ReactAndroid:buildReactNdkLib

2）我通过创建符号链接

来修复上述错误

arm-linux-androideabi-4.9 - ＆gt;臂-Linux的androideabi-4.8

3）下一个错误：

使用RN文档中提供的NDK v11，而不是Google页面上提供的v12。
