UDP library (hypermedia.net.*;) not working in android mode?

It looks like I can’t receive UDP on in android mode.
I have set all sketch permissions “on”
If I use the artnet library in android mode then I receive UDP, but need other ports and data now…
What am I doing wrong???
Simple sketch below, just to see if I receive anything at all?

<

import android.os.Bundle;
import android.view.WindowManager;

void onCreate(Bundle bundle) {
  super.onCreate(bundle);
  getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
}

import hypermedia.net.*;
UDP udp;  // define the UDP object

int dataint3=5;

PFont f;

void setup() {
  fullScreen(P2D);
  orientation(LANDSCAPE);
  udp = new UDP( this, 6454 );
  udp.listen( true );
  background(102);
  printArray(PFont.list());
  f = createFont("SpaceMono-Regular.ttf", 102);
  textFont(f);
}

void draw() {
  background(102);
  text(dataint3, 600, 600);
}

void receive( byte[] data ) { 			// <-- default handler
dataint3=22;
}

Sorry, does work after reset Phone…
