Android Studio 无法找到 Oculus SDK。

Question

我刚刚在我的项目中添加了一个库——Gear VRF，但是该库的build.gradle文件无法找到Oculus sdk。我得到了错误信息“未复制Oculus文件：未找到OVR_MOBILE_SDK”，以及“依赖硬编码路径和环境变量；未找到OVR_MOBILE_SDK”。在Gradle日志底部还有“framework:buildNative任务执行失败，User/../../Android/sdk/ndk-bundle/ndk-build以非零退出值2结束”的信息。

对于这个问题的任何帮助都将不胜感激，下面是该库的build.gradle代码，请查看一下，谢谢。

找到gradle.properties文件并添加以下内容：

# Un-comment and add the path to ovr directory
OVR_MOBILE_SDK=\.\.\/GearVRf\/ovr_mobile_sdk
