I'm currently stuck trying to convert a Java.Nio.ByteBuffer to an array or a string in a Xamarin Android App.

byte[] outputBytes = new byte[16];
Java.Nio.Buffer outputBuffer = ByteBuffer.Wrap(outputBytes);
//... filling buffer (using tflite model)
byte[] bufferBytes = ???

How can I get the content of the buffer?

Apparently there is a function like buffer.array(), but it doesn't work here.

So if anyone has an idea how i can make this work or any other way, help would be really appreciated.

  • Not a duplicate. Suggestions in first link don't work due to working in another environment (I guess), which is exactly the problem here. Commented Jan 27, 2020 at 16:25
  • Second one too, I'm not writing plain java code, I can't access the methods mentioned. Commented Jan 27, 2020 at 16:27

  • The first one actually looks like it might help, but I'm getting this with every method I tried: Error CS1061 "Buffer" does not contain a definition for "GetFloat", and no accessible GetFloat extension method that accepts a first argument of type "Buffer" could be found (a using directive or assembly reference may be missing).
