AndroidStudio NDK使用传统make文件进行调试

根据链接见子标题“usingandroid.mk/Application.mk”，文章声称可以使用androidstudio进行编辑和调试。我已经按照那篇文章中的所有说明进行了操作，但是调试器似乎从未达到断点。这对谁有用吗

更多信息

我的设置

Android Studio 1.4

梯度2.6

Android Gradle插件0.3.0-alpha5

我的身材，格雷德尔看起来像这样

应用插件：“com.android.model.application”

模型{ 安卓{ compileSdkVersion=21 buildToolsVersion=“23.0.0 rc2”

}

我的本机源在app/src/jni中的源之间分割，并且位于FS的不同位置（因为有些源是第三方的）

代码完成工作良好（我能够在第三方源代码中包含并使用源代码）

我在外部使用Android.mk和Application.mk以及ndk构建所有本机源代码。SO文件在jniLibs下生成，应用程序运行良好

当我在本机源中的app/src/jni或第三方源位置下设置断点时，调试器不会命中它们。

使用传统makefile编译时，会生成如下结构：

-obj 
  -local
    -armeabi-v7a
        -obj-debub
         xxx.o
         xxx.d
         zzz.o
         zzz.d 
      hello-jni.so 

使用Android Studio调试的诀窍是jniLibs块的配置。必须如下所示：

main.jniLibs {
            source {
//                srcDirs = ['src/main/libs']
                srcDirs = ['src/main/obj/local']
            }
        }

为了不存疑，我的渐变看起来像这样。
