Android Studio中c库的gradle构建失败

首先，我要说我对Gradle、Android Studio和Git都是新手。我们刚刚从Eclipse和SVN迁移到这些技术，在运行Android项目时遇到了一些问题。我们正在Mac上开发。我从另一个团队继承了这个项目，不确定他们为什么选择做某些事情。 [不幸的是，我不得不在整个截图中审查项目名称和用户。]

我们正在使用c ogg库在Android应用程序中录制音频文件

我们收到的错误是：

我们已经找到了和的链接，但我们无法让它们中的任何一个正常工作

我们不确定该项目是否设置正确，因为似乎有很多Android.mk文件漂浮在周围

从上面的问题链接来看，我们似乎需要强迫Gradle不要用自己的Android.mk文件覆盖我们的Android.mk文件，但这些建议似乎只会让我们进一步陷入困境

有人能给我们指出正确的方向吗

我真诚地希望你能暂时解决这个问题ago@AlexCohn，我们从来没有。相反，我重写了代码，使其不需要c library.auch。但我同意，如果可以从开发堆中删除一项附加技术，整个应用程序就会变得更健康。无论如何，如果你好奇的话，新的Android Studio（2.2+）完全支持NDK构建。
