gradle build在Android Studio中的c库上失败

Question

首先让我说我是Gradle，Android Studio和Git的新手。我们刚刚从Eclipse和SVN迁移到这些技术，并且在运行我们的Android项目时遇到了一些麻烦。我们正在开发Mac。我从另一个团队继承了这个项目，并且不确定他们为什么选择做某些事情。 [不幸的是，我必须在整个屏幕截图中审查项目名称和用户。]

我们正在使用c ogg库在我们的Android应用程序中录制音频文件。

我们收到的错误是：

我们发现this blog post和this stackoverflow question链接到this other SO question，但我们无法让其中任何一个工作。

我们不确定该项目是否设置正确，因为似乎有很多Android.mk文件浮出水面。

从上面的问题链接看来，似乎我们需要强制Gradle不要用它自己覆盖我们的Android.mk文件，但这些建议似乎只能让我们进一步深入兔子洞。

有人会指出我们正确的方向吗？
