Just a simple question about your first example. I have changed the manfest as suggested and I have action bar, status bar and navigation bar colors changed.
Really wonderfull. But now I have a little problem, I have used the addmenuitem to add menu items in the bar...but the textcolor of the menu is white and the backgrund of the menu is white too, so i can't really see nothing..
I have seen the option in the manifest that set the primary color to white....
<color name="textColorPrimary">#ffffffff</color>
.. so acting on this value I can switch to color ff000000 (black) for example, and it to solve my menu problem, but on the other side, the text on the bar becomes black too, so probably I need to act on another parameter that I can't actually find.
