Hello, I’m a absolute beginner in Android Studio.  
I’m need to do a external C++ library in Android Studio with just the function exchange(string FileIn, string FileOut).

I use the sample project in the SDK. I have created a module with a simple function. All is OK with my unity project. But now I want include the SDK in this module but AndroidStudio say he doesn’t found it .  
What must I do to include the SDK in my module ?

#include \<jni.h\>  
#include   
#include \<A3DSDKIncludes.h\>

extern “C”{  
int getSomeNumber()  
{  
return 134;  
}

```
int Add (int i, int j)
{
    return i+j;
}

```

};
