Assets/scripts/fbLogin.cs(60,52): error CS1501: No overload for method `API' takes `3' arguments

i am trying to show facebook profile picture and username to the logged in user in my android game but i am facing this error:
Assets/scripts/fbLogin.cs(60,52): error CS1501: No overload for method API' takes 3’ arguments

                    void DealFBMenue ( bool isLoggedIn){
			if (isLoggedIn) {
					UIFBIsLoggedIn.SetActive (true);
					UIFBIsNotLoggedIn.SetActive (false);

					//get profile pic code
					FB.API ("me/picture?type=med", HttpMethod.GET, DealWithProfileImg);
			} else {
					UIFBIsLoggedIn.SetActive (false);
					UIFBIsNotLoggedIn.SetActive (true);
			}
	}
	private void DealWithProfileImg(GraphResult result){
			if(result.Error == null){
				Image img = UIFBPPic.GetComponent<Image>();
					img.sprite = Sprite.Create(result.Texture, new Rect (0, 0, 128, 128), new Vector2());
				}
			}

I think it takes 4 parameters.
-query
-method
-callback
-formData

You are only providing query,method and formData. You are missing a callback.
