With respect, that does not answer the question. It is like saying that if you want to remove a stain on your wall, you have to knock the wall down.
I too would like to remove the android logo or hide it - but I do not want to remove the title bar, which contains the system icon for accessing the "help" menu I have just spent hours setting up.
Many apps have a custom logo and other action icons in the title bar area. Do they do this by hiding the original bar and placing a panel where it was ?
