Getting byte[] or ByteBuffer[] from native Java

Question

Hello,

I have a native Android plugin that has a method that does somet$$anonymous$$ng and returns ByteBuffer[]. I could change it to possibly return byte[].

My problem is that I can't seem to call that method from Unity..... I have triad to to t$$anonymous$$s in the following way:

 classInstance.Call<AndroidJavaObject>("methodName", 0);

or

 classInstance.Call<byte[]>("methodName", 0);

The Java method looks somet$$anonymous$$ng like:

 public static byte[] methodName(int index){
     byte[] b = w/e
     return b;
 }

I have triad making the method static or not static. In all cases, I get the following error:

AndroidJavaException: java.lang.NoSuchMethodError: no static method with name='methodName' signature='(I)Ljava/lang/Object;' in class Ljava.lang.Object;

Any ideas as how I can t$$anonymous$$s t$$anonymous$$s to work? (getting the ByteBuffer[] is preferred but getting byte[] is also ok)

Thanks!

It's a static method, so NoSuchMethodError makes sense, you're trying to call instance method "methodName".

Remove the 'static' modifier if you can, otherwise try using AndroidJavaClass and CallStatic:

 AndroidJavaClass myClass = new AndroidJavaClass("com.myPackage.myClass");
 byte[] result = myClass.CallStatic("methodName", 0);
