Passing arrays back to c# from JAVA using AndroidJavaProxy

Unity Engine

It seems like the default behavior of the function AndroidJavaProxy.Invoke() does not support arrays (at least of primitive JAVA variable types. (I am using 2017.1) I can retrieve the array (e.g., int[ ]) from within the Invoke() by using:

override public AndroidJavaObject Invoke(string methodName, AndroidJavaObject [ ] javaArgs){
AndroidJavaObject arg1 = javaArgs [0];
int [ ] arrcopy = arg1.Call<int[ ]> (“clone”, new object[0]);
}

However, this seems to require calling the clone() function, which copies the JAVA array. Is there a way to avoid this excessive copy? One way I could think of is to use a dummy class as the argument that holds the array in a member variable, then the Invoke() would call the get function that simply returns the array. Is there an easier way of converting the AndroidJavaObject directly to a c# array?

Thanks in advance,

Does anyone at Unity know anything about this? I know there is a workaround, but it would be good if you could point me to some documentation that shows how to do this. Thanks, Blaine
