在 android studio 上使用 Oboe 时出现未知警告选项“-Wshadow-field”错误

Question

我使用 android studio 创建了一个 ndk 项目，一切顺利，我可以毫无问题地在模拟器上启动我的应用程序。但是当我将 Oboe 库添加到我的项目时，当我尝试启动或构建我的应用程序时会出现此错误。我正在为这个应用程序使用 c++14。我认为 clang 有一些问题，但我不知道如何解决它。

这是错误日志、Cmake 文件和 build.gradle 文件：

    }

谢谢@Michael。问题来自 NDK 版本。但如果有人遇到此问题，请确保拥有最新的 andriod studio 版本和最新的 gradle 版本。因为它需要。
