Libgdx + Box2d = ~8 fps on android?

Heyho folks ^^

I was wondering about my performance on an android.
Just to test i made a very simple “Game” where i just make a world (box2d) + renderer and cam.
I have added 1 Body with this code:


BodyDef circleDef = new BodyDef();
		circleDef.type = BodyType.DynamicBody;
		circleDef.position.set(80, 120);
		
		Body circleBody = world.createBody(circleDef);
		
		CircleShape cs = new CircleShape();
		cs.setRadius(1);
		
		FixtureDef fd = new FixtureDef();
		fd.shape = cs;
		fd.density = 1;
		fd.friction = 0.2f;
		fd.restitution = 0.8f;
		
		circleBody.createFixture(fd);
		return circleBody;

here is my rendering method :


public void update(float delta)
	{
		renderer.render(world, cam.combined);
		world.step(1/60f, 6, 2);
	}

now on my comp i have got like 60 fps thats okay but after launching on android it drops to ~8 fps o.O and this is not suitable for me =(

its the first time im working with android and my second time working with libgdx.

My question is:
can i somehow get this running on android or should i just forget it? (btw. i cant connect a real android atm so i use the AVD for Nexus One made out of the given Device Definitions)
