I'm trying to get the F0 of a wave to be displayed on the screen of an Android app, so I'm using:
receiver.receiveFloat("sent", f0);
textView.setText(String.valueOf(f0));
And although if I add a receiver within the patch the numbers are indeed received, Android is not really displaying anything.

Now I've tried writing the numbers in an array and still, although it works within the patch and although I'm using a readArray function which is almost identical to the one I'm using to read the other array, I'm getting nothing.

I eventually found out what the problem was; neither {sigmund~} nor any other pitch-tracking object are really vanilla objects. I still haven't found a solution though, so any help will be appreciated.
