popupMessage.showAsDropDown() generating null pointer exception

I am receiving a null pointer exception that I would like some assistance in understanding why. I am creating a custom pull-down drawer. I have a view, that appears over my Activity on button press (for now, until I implement the fling). This is how I am setting up my PopupWindow

popupMessage = new PopupWindow(view, LayoutParams.MATCH_PARENT,
                LayoutParams.WRAP_CONTENT, true);
        popupMessage.setContentView(view);
        // Clear the default translucent background
        popupMessage.setBackgroundDrawable(null);
        if(userType != null){
            if (userType.contentEquals("kid")) {
                popupMessage.setFocusable(false);
            } else {
                popupMessage.setFocusable(true);
            }
        }
        popupMessage.setOutsideTouchable(true);
        popupMessage.setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
        popupMessage.setAnimationStyle(R.style.PopupAnimation);
        popupMessage.update();

        // Icon is an imageVIew ** This is where the null pointer occurs **
        popupMessage.showAsDropDown(icon, 0, -(35+8));

Why would this cause a null pointer exception? I have also tried

popupMessage.showAtLocation(icon, Gravity.TOP|Gravity.LEFT, 0, 0);

Here are my logs

popupMessage is obviously not null since you are able to do methods on the instance before the null pointer. Thus my guess is that icon is null, please confirm if this is the case.

popupMessage.setOutsideTouchable(true);
popupMessage.setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
popupMessage.setAnimationStyle(R.style.PopupAnimation);
popupMessage.update();

// Icon is an imageVIew ** This is where the null pointer occurs **
popupMessage.showAsDropDown(icon, 0, -(35+8));
