LIBGDX wont print out the resolution of my phone. -SIMPLE

if i run desktop launcher it will, but not when i run it on my phone. I dont understand. should i be putting something in the android launcher? Like it doesnt system.out anything =/

public void create {
SCREEN_WIDTH = Gdx.graphics.getWidth();
SCREEN_HEIGHT = Gdx.graphics.getHeight();
System.out.println("w “+SCREEN_WIDTH+” x h "+SCREEN_HEIGHT);
setScreen(new game());

}
