I've been wanting to add an image to my notification dropdown by editing files in SystemUI.apk, but after decompiling it, it turns out I have no idea which files need to be edited!

I'm at something of a loss. Anyone know what files/lines need to be edited? There are so many different status_bar files....



For what it's worth, I'm on Verizon, but I doubt the necessary files/lines change much between carriers.
